STILLEN Dealer Profile: Infiniti of Melbourne x STILLEN Q60 Red Sport

20170715_145747

The twin-turbocharged Infiniti Q60 Red Sport has been gaining traction with the aftermarket as development progresses on this exciting new luxury coupe. This is evident to us here at STILLEN, as we get feedback from our vast network of partner dealerships. One such dealership, Infiniti of Melbourne in Melbourne, Florida, has seen an increase in the sales of the Q60.

20170715_145744

Body Styling and Lowering are on the Rise

In conjunction with this rise in sales is a corresponding increase in aftermarket upgrades purchased. We spoke to Infiniti of Melbourne’s Parts Department manager, Luke Degraff, who shared some of his observations. “The increased sales of the Q60 coupe, along with its sedan sibling, the Q50, have led to an increase in aftermarket parts sales, especially the STILLEN Unpainted Front Bumper Splitter for 2017 Infiniti Q60 and the STILLEN Rear Valance Diffuser for 2014-2017 Infiniti Q50. A good number of customers have also chosen to lower their new Q50 or Q60 with a set of RS-R Lowering Springs for 2009+ Infiniti Q60 RWD (N120D). We chose Vossen Wheels to complete the showroom model. The presentation has been very well received!”

The STILLEN equipped Q60 was a hit at Infiniti of Melbourne’s Cars and Coffee event this past Saturday, July 22.

Infiniti of Melbourne also hosts a Cars and Coffee event at the dealership. During the recent event held last Saturday, July 22, 2017, the STILLEN/RS-R/Vossen equipped Q60 drew plenty of attention from visitors checking out the vehicles on display.

STILLEN News: STILLEN Cold Air Intakes Receive A.R.B. Exemption

May 26, 2017

Street-legal status equates to being able to smog and register your car with ease while avoiding fix-it tickets and visits to the courts and/or the state referee. This becomes particularly important if you live in California or any of the 49 other States of America that subscribe to California’s style of stringent emissions requirements.

IMG_6976

Developing performance products that achieve street-legal status involve a significant investment of research, development, time and money. To this end, STILLEN prides itself on the engineering time invested to garner measurable performance while maintaining compliance with the standards set forth by the Air Resources Board (A.R.B.). STILLEN employs a Nissan “CONSULT III” diagnostics computer to monitor and log vital data channels to ensure reliable and consistent performance. This means that STILLEN Intake Systems do not require ECU calibration and are a truly “Plug and Play” performance upgrade. No “check engine” lights and no idling issues.

402962

Obtaining an Executive Order from the A.R.B. involves prototyping and testing to prove that our STILLEN Intake Systems do not affect the vehicle emissions control devices. Periodically, we resubmit and update our product listings with new products as well as updates to existing part numbers and additional qualifying vehicle applications. STILLEN’s most recent release included the highly anticipated VR30DDTT Intake System for twin turbocharged 2016+ Infiniti vehicles (p/n 402856, 402856DF).

STILLEN Short Ram Intake for the Turbocharged Infiniti Q50 Sport and Red Sport 3.0T

402856_IMG_01_2016_UP_Infiniti_Q50_Q60_intake_Overall

(p/n 402856, 402856DF)

402856_IMG_06_2016_UP_Infiniti_Q50_Q60_intake

Infiniti breathed some forced induction life into the Q50 Sport and Red Sport models with the inclusion of its all new, twin turbocharged VR30DDTT V6 engine. Conservatively rated from the factory with 300 horsepower (in the Sport) and 400 horsepower (in the Red Sport), these new “Q’s” make decent power off the showroom floor. However, like any turbocharged engine, reducing air flow restrictions allow a turbocharger to spool up more quickly while efficiently generating boost pressure. This translates into improved response, greater incremental gains and oftentimes, more peak power.

402856_IMG_02_2016_UP_Infiniti_Q50_Q60_intake_Cover_off

As a longtime specialist in the world of Nissan and Infiniti, STILLEN takes great pride in the engineering of its products. Having seen the performance potential in the new 3.0-liter twin-turbocharged V6, our engineers set out to develop an intake system that produced the greatest performance gains without triggering the dreaded “Check Engine Light” error or requiring a custom tune.

402856_IMG_04_2016_UP_Infiniti_Q50_Q60_intake_filter

 

Unlike any other intake manufacturer, STILLEN’s longstanding relationship with Nissan helped to facilitate a genuine Nissan factory CONSULT diagnostics computer. Monitoring data channels that most in the aftermarket cannot, STILLEN engineers tested more than 20 different intake designs, evaluating numerous variables and noting the effects on specifics such as fuel trim, velocity and temperature, to name just a few. While the sheer number of prototypes might seem like overkill, the data collected enabled STILLEN to optimize the intake design for output and presentation.

Automotive customization is really starting to hit the mainstream more often these days. You used to walk into a dealership, pick your color and a few options and that was the extent of the customization available at the dealer. However, things are changing, and for the better. More manufacturers and dealerships understand that consumers want their vehicle to be unique and reflect their personality. Automakers now offer more trim packages, color combos and more elaborate accessories than ever before. While this has satisfied a number of buyers, some dealerships realize that their customers wanted more.

Funding to modify a brand new vehicle often poses a hardship, as consumers generally spend a good amount on the down payment in order to make the monthly payments more palatable. Often times, this doesn’t leave a lot of cash for customization. Bennett Infiniti of Wilkes-Barre, PA understood the dilemma and decided to offer its customers the opportunity to drive off the lot with a customized ride. When this dealership modifies the car for you at the time of purchase with parts sourced directly from STILLEN, the cost can be rolled into your financing. This means you can add some nice modifications for approximately $40-$120/month (amount varies depending on cost of parts and labor).

Here is a great example of a modified Q50 Red Sport AWD that Bennett Infiniti put together. They installed the STILLEN Front Splitter, Side Splitters, Rear Diffuser and Wing to really give the Red Sport a more appropriate and aggressive appearance.

2017 Q50 Red Sport AWD STILLEN

The dealership informed us that the modified cars on the showroom floor always garner the most attention and it’s easy to see why. So next time you are in the market for a new car and want it modified, you know where to look!

The VR30DDTT is an impressive motor. It is underrated from the factory as we have seen with dyno testing. The Hi-Output version is rated at 400 hp and 350 ft-lbs at the crank and the Low-Output version is rated at 300 hp and 300 ft-lbs at the crank. We have consistently seen ~375 whp and ~350 wtq from the Red Sport Q50’s and Q60’s and ~300 whp and ~290 wtq from the “300 hp” versions.

That being said, everyone is still excited to see what these motors can do. With factory forced induction there is often a ton of room for gains when you simply tune the car and crank the boost up. Now there is a lot to consider before assuming power gains by simply increasing boost and tuning. So strap on your thinking caps and prepare for the math!

The factory turbos on the VR30 are produced by Honeywell-Garrett. The model of the turbo is MGT14446LKSZ. We could talk technical specifications*, but in the end let us just say the turbos are small. What is more important is we have the turbo map for the MGT1446 turbo. This has allowed us to see what efficiency range the turbos are operating under stock boost, as well as the limits of the turbos when it comes to boost levels and power gains.

compressor-map-garrett

We can see the VR30 Red Sport (400) boost curve looks something like this. With this knowledge, we can run a series of calculations to see the efficiency of the turbos throughout the RPM range.

q50_ficbe_ldp_vs_stock_large

For everyone who would like to do the math themselves the basic formulas are as follows.
Cubic Feet/Min:

cfm-formula
Corrected Air Flow (CAF) lbs/min:

caf-formula
Pressure Ratio (PR):

p-formula

So for stock boost our table will look like this:
*we use 1.5 liters as displacement as only half the motor feeds each turbo.

Q50 Red Sport – Stock (14.5 PSI)
400-hp-stock-turbo-table

Utilizing the same formula and increasing boost, we made a graph then overlaid onto the Turbo Map. We included the Low-Output graph for reference as well.

q50-turbo-map-hi-and-low-output1

You can see that even at stock boost (for the Red Sport) the turbos are off the efficiency island (below 60%) post 5750 RPM. So what happens as you move off the island? As turbo efficiency goes down you begin to generate more and more heat for the given boost pressure.

If you look at the stock dyno sheet, you can see where the horsepower curve begins to flatten out at around 5000 RPM. We have also seen with an aftermarket exhaust and secondary cat deletes the gains past the 5000 RPM area are far less significant. This can pretty much all be attributed to the turbos.

2017 Q50 Red Sport Dyno

2017 Q50 Red Sport 3.0tt Stock Dyno Sheet

We went ahead and also did graphs of increased boost pressure following the factory curve up to max pressure. We assume the lower boost pressure below 4000 RPM is to keep the torque under control for driveability’s sake.

turbo-mapping-vr30ddtt-with-notes

Looking at the chart, one can see that as you increase the maximum boost levels you move out of the efficiency island very quickly. At 17 PSI you move below 60% efficiency at 5500 RPM which is not much worse than stock. However, once we get into the 19 PSI Range you can see us leave efficiency by 5250 RPM. On top of that we are moving over 23.6 lbs/min (or 342 CFM) at 6250 RPM very far outside of the efficiency island. This puts a lot of stress on both the engine and turbos.

So aside from changing the turbos (which there are no upgrades available at this time), what can we do to safely increase power? We believe it is unwise to spin these turbos much past 17 psi in search of a lot more power (at least above 5000 RPM). So with a moderate increase in boost pressure, the name of the power game will be EFFICIENCY (yes I’m sure you’re tired of reading that word).

Restrictions:

With any factory setup, there are going to be restrictions. Some are cost related, some are emissions related, and some are Noise/Vibration/Harshness (NVH) related.

We already know the first restriction point lies in the intakes. Factory intake systems are the first point of emissions and sound control on a car. The STILLEN intakes have already shown impressive gains in the mid-range powerband. This makes sense as the highest efficiency range of the turbo at factory boost levels (and even elevated boost levels) will be in the 3250-5000 RPM range.

The factory exhaust system on the VR30 powered cars is definitely a bottleneck as well. We know the secondary catalytic converters narrow down to 1.5 inches (diameter) just before the cat-back. On top of that the factory cat-back exhaust is a mere 1.75 inches (diameter). Now removing the factory catalytic converters is frowned upon by the EPA, so we can’t recommend changing those out. However, a cat-back exhaust is perfectly legal and voids no warranties (which we are sure most of you know). On top of giving the Q50 & Q60 the exhaust note it deserves, the cat-back greatly increases the efficiency of the turbos by reducing back pressure. This reduction in back pressure reduces the resistance on the turbines and in turn allows them to spool faster and easier. This means for the same given turbine speed, you are able to create more boost (or the same boost) with less heat.

Cooling:

While heat is necessary for an engine to run properly, too much is definitely a bad thing. While on a naturally aspirated motor, a cooler intake charge can greatly improve performance. Forced induction doesn’t yeild as impressive of results. Why is this? The air pulled through the intakes enters the turbo which compresses the air. The compression of air causes an increase in air temperature (see Boyle’s Law and Charles’ Law) which is problematic for internal combustion engines. With most forced induction setups there is an intercooler (or aftercooler) which is located between the turbo and the lower intake manifold. Said intercooler can be either an Air-to-Air or Air-to-Water system. The VR30 uses a pair of Air-to-Water intercoolers. The heat exchanger for the intercoolers (how the heat is removed from the system) is located in front of the radiator behind the grille.

The Red Sport version of the Q50 and Q60 both come with two waterpumps (push-pull) to increase cooling for the intercoolers. This makes sense as the Red Sport boost levels create a lot more heat at higher RPM than the 300 hp version. Knowing that many people will be increasing the boost of both models, everyone could definitely benefit from more cooling. While the intercooler units themselves would be difficult to upgrade since space in the engine bay is quite limited, the heat exchanger up front has some room to grow. Increasing the size of the heat exchanger does two things: allows for more heat to be extracted from the hot fluid, and increases the volume of fluid which increases the overall thermal capacity of the system. While this isn’t the ultimate solution, it would make running higher boost levels (17-18 psi) safer as well as reducing potential heat soak after prolonged aggressive driving.

Tuning:

While there is still a lot of exploring to do when it comes to tuning, there are several things we can see just by looking at the turbo map and dyno sheets. Your biggest gains will all be in the mid-range (2500-5000 RPM) with the stock turbos.

Based on the turbo map, tuning to 18 PSI from 4000-5000 RPM puts you in a very ideal efficiency range for the turbos. Now dropping the boost after 5000 RPM is important as holding too much boost is not ideal for the motor or turbos, but also won’t gain much additional power. This fine tuning of boost pressure adjustment is made easier by the factory electronically controlled wastegate actuators.

400-hp-optimal-turbo-table

q50-stock-boost-vs-optimal-boost1

While we are still waiting on the tuning companies we work with to release official software, we are confident it won’t be much longer. You can bet we are just as anxious to start tuning these cars as you are, but with any new platform the best products take a little time to develop.

infiniti_VR_engine_03

Although we probably won’t be seeing any 600 whp Q50’s or Q60’s without bigger turbos, there is still a lot of potential even on the factory units. Needless to say, we are all working on more ways to make power with this platform. STILLEN is about to release our new intake system for the 3.0t Q50 & Q60 along with our Cat-Back Exhaust for the 3.0t Q50!  Our engineering department has done a lot of work on these products and designed them with the factory setup in mind as well as future upgrades. Stay tuned (pun intended)!

2016 Infiniti Q50 3.0t Red Sport

The End of an Era Begins

With the introduction of the Q50 Twin Turbo and 2.0 turbo, 2016 marks the beginning of the end for the now famous Nissan VQ family of engines.

For nearly two decades, the Nissan V6 engines have been based on the VQ platform. These engines have been widely revered as powerful, fun, and innovative V6 mills with a distinctive sound – some would argue the “best” sound on the market.

STILLEN has always been fond of the VQ and its many variants; VQ35, VQ35DE, VQ35 rev-up, VQ35HR, VQ40 (found on the mini-truck and compact SUV line), and of course, the swan song VQ37 featuring Nissan’s progressive VVEL technology.

Nissan Returns to Its Roots

With deep respect and fond appreciation we say good-bye to the VQ. Now, we’re ushering in a new era by going back in history about 25 years.

Sound weird?

To our eyes anyway, Nissan appears to be returning to its performance roots. Long time Nissan fans know that the epitome of a performance Nissan engine is the VG30 3.0 liter V6 engine found in the Z32 chassis Nissan 300ZX. These cars were feared and respected in their time and are now considered timeless classics.

The latest excitement surrounding NISSAN power plants is the new VR30 3.0 liter V6.

See the resemblance?

The VR30 comes in two flavors, 300HP and 400HP. Needless to say, here at STILLEN we can’t wait to work on these engines.

However, it isn’t the only interesting new turbo engine available from Nissan/Infiniti.

The new Q50 is already available with a 4 cylinder turbo engine sourced from Mercedes.

Which leads us to the question…

One Turbo or Two?

Contrary to all the talk about the Infiniti Q50 and the all-new VR30 Twin Turbo, there’s been nothing but crickets about the Q50 2.0 Turbo that recently hit Infiniti showrooms.

Makes us wonder: is two the minimum number of turbos required to generate online chatter these days? Or is it more about engine displacement? Both?

Regardless, as usual the car with the smaller engine gets ignored. Here at STILLEN, we love underdogs because they usually embody the kind of performance challenge we love to take on.

And we know there’ll be plenty of enthusiasts who will pick up a Q50 4-banger and promptly begin to modify it.

So color us inspired!

Your 15 Seconds of Fame

Everyone dreams of owning that 500+ horsepower monster…the one that gets you daydreaming. You know the scenario: that magical day you line up on a Ferrari and live out everyone’s Fast and Furious fantasy.

The one where you:

  1. Win the race
  2. Shame the dude
  3. Get the girl

Ahhh yes…

Now that you’ve taken a second to imagine that scene from the movie, let’s return to reality. Because of real life concerns like budgets, insurance, significant others and gas mileage, lots of people will be purchasing the 2.0 Turbo version.

You know..the model that only has one turbo.

“One turbo? Old school, Bruh”.

Nah…the truth is, turbos in any quantity are back to stay and will likely usher in a golden era of automotive performance that we last enjoyed in the turbocharged 90’s.

No Replacement for Displacement?

Sure, bigger displacement motors will always be the dominant power plants in regards to hop up potential. There truly is no replacement for displacement after all.

And there seems to be a particular stigma in the Luxury Sport Sedan/Coupe scene about small displacement motors. While many owners now equate larger displacement 6 cylinder engines with luxury, let’s not forget that these 4 cylinder turbo motors aren’t that different that those found in other sporty cars.

A Weighty Decision

The weight differential between “pure” sports cars and “luxury” sport cars is less than you might think. For example: Subaru WRX – 3400 lbs, Audi S3 – 3400 lbs, Mitsubishi Evo – 3500 lbs. Granted, the Q50 2.0t weighs in around 3700 lbs. And yes, those other cars come from the factory with a lot more power.

However, there are plenty of indications that this engine is very capable of respectable output. We already know some versions of this motor (sourced from Mercedes) make 241 hp from the factory. The 208 hp version has been tuned to around 260 hp (and 302 lb-ft torque) with the stock turbo.

Needless to say, it appears there’s room for growth. If it’s possible to get the 2.0t into the 300 crank horsepower range, it will definitely be a blast to drive. It’d pretty much erase the 200 pound penalty and deliver all the real world benefits of a smaller displacement engine (insurance, gas mileage, happy girlfriend, boyfriend, spouse, etc).

Go Fast Bits – Developing Q50 Turbo Aftermarket Parts

STILLEN has already confirmed fitment of our body styling polyurethane parts (Splitter, Diffuser, Side Splitters, Roof Wing, and Deck Wing), Axle-Back Exhaust, and Rear Sway Bar. We have a cat-back exhaust in development and more goodies on the testing bench.

Handling wise, our friends at RS-R already have lowering springs and coilovers done.

So the power, performance and style parts for the 2.0t Q50 are already on tap and ready to quench your thirst.

Driving Impression: Torque to the Rescue

When Infiniti released the Q50 back in 2013 (as a 2014 model), the enthusiast community was impressed by its styling, comfort, and performance. The tried and true VQ37 provided ample power for a bit of fun and that refined feeling. It was only a matter of time before Infiniti followed the market trend and began spec’ing a small displacement turbo engine for the base model. Like most people, we thought this was a bit of a travesty (we’d grown rather fond of the raspy V6).

Now that we finally got a chance to drive the 2016 version of the small displacement Q50…it’s..not so bad.

At the bottom end, horsepower feels a bit anemic, but a dose of torque on the low end of the curve helps move things off the line.

At the other end of the spectrum, the car definitely lacks the top end power we were accustomed to with the previous engine. Once you pass about 5K rpm it feels like the motor is being reined in. The power stops building and the acceleration falls off a bit.

It isn’t terrible, but it’s a little disappointing to say the least.

Good News Travel Fast

The good new is, our initial testing with exhaust parts has definitely yielded improved feel in top end power. This hints that the car will be very responsive to mods. Who knows…maybe a STILLEN modified 2.0t will end up being faster than the VQ37 equipped Q50’s. Time will tell.

The Infiniti VR30 twin turbo might be one of the most hotly debated and anticipated engine design in years.  All the comments flying around the forums and blogs about a “cheap 600+ whp car” might make you wonder: is it wishful thinking, or an attainable goal?

For starters, the VR30 is not the same animal as the VG30 or a similar bulletproof iron block monsters of the 90’s. It’s also not a hand-built GTR motor already making 500+ hp.  Still, it’s all conjecture, and up until now Infiniti hasn’t released enough information to help separate fact from fantasy.

You may recall a few months ago we looked at the new VR30 Twin Turbo motor from an aftermarket perspective based on the information given at the time (An Aftermarket perspective on the new Nissan/Infiniti VR 3.0 Twin Turbo V6). Recently Infiniti released some “Technical Cinemagraphs” offering a closer look at this new engine. These Cinemagraphs give us a lot more information about the motor design and what we might be able to improve upon.

Twin Turbos and Two Outputs

As we already know, the VR30 will be a 3.0-liter V6 Twin-Turbo Engine with two output variations: one producing 300hp and the other a whopping 400hp. We covered the differences in the last blog post, so armed with fresh information we can look at areas we feel might yield results.

Intake Manifold and Intercoolers

Starting at the top with the most obvious (however not the cheapest) potential upgrade: the intake manifold. As you can see, the design of the intake manifold looks ideal for “packaging”. Looking at the diagram below you can see some of the restriction points as well as areas that are susceptible to turbulence. While this will work fine and is great for a the stock setup, it leaves room for potential improvement.

 

Take a look at the Nissan GTR Intake Manifold Design below. A larger plenum (which the OEM design doesn’t really have) helps take care of air starvation issue before the boost fully kicks in. The shape of the plenum creates less turbulence and feeds more directly into the runners. With this type of manifold, the runner lengths could also be optimized for performance. Coupled with the possibility of switching from an Air to Water to an Air to Air Intercooler setup (which would free up the space on top of the motor), a GTR-esque Intake Manifold would potentially yield serious gains.

Intercooler Conundrum

We discussed an Air to Air Intercooler setup in the last article.  There are potentially limitations to the factory intercoolers as they were designed for a specific amount of power and boost. Also, with an increase in boost the almost 90° turn the air has to make could create another restriction point. If we can fit a front mount Air to Air Intercooler it could allow for a safer increase in boost and squeeze a lot more juice out of this new 3 liter.

You might say: “But STILLEN, what about the turbo lag from the increased distance between the turbo and throttle body?” While greater distance between the turbo and throttle bodies can increase the time it takes for the pressure to build, the effect is so negligible it’s not worth worrying about. The real difficulty lies with fitting all the plumbing in. We know what the Q50 engine bay looks like and an Air to Air Intercooler setup will prove very challenging. We hope that the Q60 gives us a little more space to work with. If not it should still be possible to upgrade the pump and heat exchanger for the Air to Water Setup, and/or upgrade the intercoolers themselves. However, because of the space restrictions, upgrading the actual intercoolers may be difficult.

High Flow Intakes

The next power grab opportunity is the intakes (everything pre-turbo). A visual analysis of the OEM design reveals an air flow path that can definitely be smoothed out. Understanding that Nissan/Infiniti had the parameters of the EPA to follow and NVH (Noise, Vibration, and Harshness) standards to meet, we know why they went with this design. Fortunately for us this leaves some room for improvement.

 

The air coming through the air boxes is forced through the restrictive panel filter, then takes a hard 90° turn over the Mass Air Flow Sensor (MAF) which is not ideal because of turbulence created by this design. It then executes yet another 90° turn before reaching the turbos. Simply reducing the number of turns in the system and creating a smoother path for the air as it passes over the MAF will allow for more accurate readings (helpful in tuning) as well as less restriction. The restriction can also contribute to a significant power loss. On other modern turbo powerplants, we have observed notable power gains by simply adding a high flow intake which can increase the boost (boost can be limited by restrictions on the intake side of both Turbo’s and Superchargers).

Exhaust & Turbos

Exhaust system modifications on turbo cars always generate power gains. Down pipes and cat-backs are already a given for the VR30 and will be available from STILLEN. Now we finally got a look at the cylinder head to turbo interface so we can see what might be done about turbo upgrades.

 

Looking at the design of the turbo flange, it appears that fabricating an adapter for aftermarket turbos should be pretty simple. Though we don’t know specs on the turbos yet, it won’t be difficult to sort out good upgrade options for those looking to make a lot more power. The only limiting factor might be space, but most upgrades shouldn’t pose an issue.

 

We still need more information about the engine internals before we can be more specific about turbo upgrades and increased boost. However, most Nissan/Infiniti Motors tend to be pretty hearty. The old VG30’s were capable of 550-600 whp with a healthy block and the VQ37’s held up to about 500 whp on stock internals (with Turbo Kits). It seems fairly safe to assume we be able to get this motor close to the 500 whp mark without reliability issues. The 600 whp mark that everyone is hoping for might be a possibility, but it will depend on the strength of the internals.

 

We will be getting a few VR30 equipped test vehicles delivered to STILLEN in the next few months. We can’t wait to get our hands on them and start doing some real world testing. Stay tuned for more articles and info on the VR30 as we continue to learn more about this motor!

With so much hype around the Infiniti Q50 and the new Twin Turbo V6 it will be receiving we think some people forgot that the new Q60 was being released soon. Well, today all of you two door lovers out there got a big treat.

 

Infiniti released the 2017 Q60 today at the Detroit Auto Show and it is beautiful. The new Q60 will come with the same engine options as the 2017 Q50. A 400 HP (350 lb-ft) Twin Turbo V6 at the top of the line up, a 300 HP (295 lb-ft) Twin Turbo V6 will be the middle option, and the entry motor will be a 208 HP (258 lb-ft) 2.0 Turbo Inline 4 (for more analysis on the Twin Turbo V6 motor please see our blog article “An Aftermarket perspective on the new Nissan/Infiniti VR 3.0 Twin Turbo V6“).

It is not clear yet, but it seems all versions will be available with AWD. Twin Turbo V6 variants will come with the 2nd generation of the Direct Adaptive Steering (DAS) which will hopefully prove to be much better than the first generation. Infiniti is also adding a 2nd suspension option that they are calling the Dynamic Digital Suspension (Standard on Sport Models) which will allow you set you suspension for the right occasion.

 

All of these new options and upgrades made the Infiniti Q60 a much more appealing car in a very competitive segment. Though the 400 HP variant will probably run in the $50k range, we are certain that the mid level 300 HP Version will be able to be modified to compete with the big boys the way the BMW 435i has compared to the M3.
