Best Driver's Car Contenders Part 3: Viper ACR, F-Type SVR, 911 Carrera S, GT-R


 
The awesomeness that is the 2016 Best Driver's Car competition continues as we introduce the four final contenders, which include the 2016 Dodge Viper ACR, 2017 Jaguar F-Type SVR, 2017 Porsche 911 Carrera S, and 2017 Nissan GT-R.
Don't miss Randy Pobst's test-track impressions on each car, below.
More 2016 Best Driver's Car content:
The Dodge Viper has always had a reputation of being a car that's hard to drive. Yeah, with its big 8.4-liter V-10 up front, now churning out 645 hp and 600 lb-ft of torque, it's fast like it always has been, but that speed has never been easy to manage.
The Dodge Viper ACR seeks to change things. Equipped with a massive rear spoiler good for almost a ton of downforce at top speed, dive planes, a big front splitter, and loads of other aero add-ons, the Viper ACR looks more race car than road car. Dodge's SRT team didn't stop there; the ACR also gets unique 10-setting adjustable coil-over Bilstein shocks at each corner, and both compression and rebound adjustable with the turn of a dial. To go with the new shocks, Dodge partnered with Brembo to provide big carbon-ceramic brakes at each corner and with Kumho to develop super sticky street-legal race tires. To round things out, the Viper ACR gives the driver a five-point harness and a six-speed manual gearbox to work with.
People, that right there is a race car! Those giant wings, the diffuser, and the spoiler! They work! The grip level is just outrageously huge compared to the other street cars that we're driving it against here today.
On a racetrack, it actually feels so slow that it feels like the shift takes forever because you're accelerating, clutch in, lift, move the lever, clutch out. Compared to these good dual-clutch modern automatics that are just snapping off the gears, it seems really antique, to tell you the truth, and I hate saying that because I love shifting. The Viper is a car where I'm using second gear in almost every corner because the car is geared so tall. It just—the engine makes its power high in the rev range. Even though it's a giant 8.4-liter, 10-cylinder engine, it still likes to rev.
What I really liked about the Viper was the braking. Mazda Raceway is so much of a braking track. With the Viper, we go deep into the brake zone, and when I go to the brake—POW—you get max-braking g, instantly. I mean, it happens right away. And that helps shorten up the brake zones, and it's very much a confidence-inspiring thing.
"I was driving the car and consciously thinking about all the downforce. Thinking, ""Don't slow down too much. Don't over-slow these corners, and enter fast."" It's very stable on entry, and it rewards going in there hot. That's where a lot of lap time is here, and actually that's a lot of fun. It just—it takes a little time to get used to it. I think I kept driving it better and better."
When Jaguar's angriest F-Type, the supercharged V-8 R, showed up to compete in our 2014 BDC event, we loved the scorching straight-line performance its 550 hp and 502 lb-ft of torque spooled out. But none of us, including ace shoe Randy Pobst, felt like the chassis had been sufficiently fortified to contend with all the R's additional power. In short, it was an oversteering handful—on turn-in, mid-corner, and when powering out of a curve. So for 2016, the R got all-wheel drive, and we carped about that system pushing too much in corners. This year that bedeviled R cat adds an S, a V, 25 hp, 14 lb-ft, and a thorough going-through of its suspension—revised bars, fatter tires, tweaked damping, and a reprogramming of the electronic handling aids (including the brake-based rear torque-vectoring system). Can these improvements better the Jag's ninth-place 2014 finish?
I am in love with this car. It's by far the best-handling Jaguar I've driven. The chassis balance was so beautiful. After I drove a couple cars that were kind of oversteer-y, the Jaguar was just beautiful on corner entry. You just have to be patient on the throttle or trail brake it a little bit, and it just turns right in—it's like I'm carving the friction circle. The all-wheel-drive system is a huge success at all speeds. Power doesn't seem to change the car's balance a lot in different gears and at different speeds. The SVR team has really made an accomplishment here on their setup of the all-wheel-drive system and the suspension. Braking was confidence-inspiring and firm. The pedal stayed firm. Stopping power was strong. I thought the braking effectiveness and cornering grip were really good for a P Zero, which is a decent street tire that seldom holds up on the track, but they did. The throttle is too aggressive, and I don't like the transmission shift programming— it was frustrating on track. It would downshift in braking zones but wouldn't get down to the right gear for exit, and it would kick down in drive, Sport, and manual. But it's a huge step forward for Jaguar.
Since we renamed it Best Driver's Car in 2009, a Cayman S and two 911s have won BDC, so the guys at Porsche firmly believe they know what it takes to bring the trophy back home to Zuffenhausen. After last year's top step Cayman GT4 failed to best the field, it was no surprise that Porsche opted to send the latest iteration of its two-time champ, the newly turbocharged, 420-horsepower 911 Carrera S. It's stunning Miami Blue paint sent a lot of friends and acquaintances sliding into our DMs about clandestine drives and ridealongs, but the real beauty of this 991.2 was how cleverly it was optioned.
Base price on our 911 C2S is $104,450, but as equipped it sits at $140,465, thanks to some carefully considered sport driving goodies, including Porsche Ceramic Composite Brakes ($8,520), the Porsche Doppelkupplung (PDK) 7-speed transmission ($3,200), Porsche Dynamic Chassis Control (PDCC) with PASM Sport Suspension ($4,050), 4-way adjustable sport seats ($440), sunroof delete ($0) and rear-axle steering and sport exhaust ($6,810 bundled together). The leftover cash went to things like leather, heated/cooled seats, and body colored painted bits inside.
Was the drive worth the extra scratch? Check out Randy's video above and comments below.
"""What a fabulous driver's car. On track, I had no sense that it had a turbo engine. It just felt like a 911 - and sounded like one with the flat-six raspy exhaust note we know. It had a broader torque curve, frankly. That might have been the only clue; it's got more torque in the mid-range than the old normally aspirated engines, but they rev out the same. It pulls strong, up to high revs."""
"""The PDK gear box, I just leave it in automatic, and that baby always knows what I want to do. It's always right there. It's on Pirelli P Zeros, which is just a normal street tire - I mean, yeah, ultra-high, extreme performance summer tire - but the grip from these new Pirelli's is actually impressing me. A real step ahead of the old one."""
"""The 911 exhibited the advantages of rear-weight distribution, which include good potential for putting power down, because the weight is on the rear tires for traction. Because the weight is in the rear, when you brake, the car is better balanced. """
"""The stopping was incredible and again, these new Pirellis are impressive in that regard. The car rotated, but it was a beautiful thing; it's just so much fun to run that on track. I did a couple extra laps. I didn't want to come in. I was hoping that everybody was looking at the lap times to see if I was as consistent as I felt like I was, because I could put that car right where I wanted. It is a superb driver's car."""
But is it our 2016 Best Driver's Car? Stay tuned…
A perennial Best Driver's Car candidate, the Nissan GT-R has shown well but never reached the podium. Could this finally be the year? With the most extensive updates to the car to date, there's a compelling on-paper case to be made.
The 2017 GT-R's updates start at its core, where its frame has been strengthened to reduce chassis flex. Moving outward, an updated interior is more comfortable and less cluttered. The engine has been upfitted with GT-R NISMO ignition control technology, which adds 24 horsepower and 4 lb-ft of torque for 565 and 467, respectively. More important than the peak numbers, the powerband has been broadened and flattened for more linear response. The seven-speed twin-clutch transmission, meanwhile, has been smoothed out with new control software.
Out in the wind, a new nose greatly increases engine-cooling capacity, and a new rear diffuser, a stiffer hood, and massaged creases keep the drag coefficient unchanged. At the corners, updated active dampers and Dunlop tires work with stronger suspension mounting points to tighten up the handling. Steel Brembo brakes are on stopping duty, pulling against super lightweight Rays wheels.
"""At turn-in, it will rotate, and I found I had to be a little careful with that. I thought I could just throw the thing into the corner, but this GTR is not a big fan of that. In fact, it doesn't like it at all. It'll get too loose at turn-in. Once the weight transfers all the way over and you're trying to aim for the apex, it starts to understeer if I've got too much speed. So it does not like a heavy trail brake late in the brake zone. I had to be a little gentler with my entry, a little more precise, a little more measured with the corner entry. And then the power was very strong. There's a big surge of torque. It's got strong, what I would call, midrange, which is probably around 4,000-4,500 rpm, so I found myself having to apex later, and then it actually drove out of the corner real nicely. But I had to be a little bit patient with the throttle or in third gear up. Third or fourth would cause understeer. It would cause understeer as a result of the power more than anything. It just accelerates so hard that it runs wide. So you need a nice late apex. It's also softer than I recall, much softer. I remember GT-Rs being known for being quite stiff, right? And I found it a little frustrating that I have an R mode, and it's still soft. And the balance was actually pretty good once I kind of got it a little bit figured out not to overdo it. Historically, GT-Rs could be driven more aggressively. And this car was not rewarding that. I had to be a little bit more precise and then it actually felt like we were going pretty fast. I've got a feeling this is probably a much better street car. The NISMO was much more race car."""

How to Build a 7-Second, 175-MPH Nissan GT-R


Text
Kenny Tran and the folks at Jotech Motorsports in Dallas were the first to develop twin-turbo kits for the VQ engine powering the 350Z, so they were more than prepared when Nissan released the GT-R in 2009. Jotech cars were running 10-second quarter miles by 2010, much quicker than the 11.6 seconds we recorded in our first test of Godzilla, though we do not test acceleration on adhesive-treated drag strips.
In the intervening years, Tran and his team continue to refine R35 GT-Rs—and they've only gotten better at doing so. Alongside the shop's six available stages of power tuning, Tran recently bought back a GT-R he had built for a friend and customer he calls DK. (No, not the DK my dad always chooses in Mario Kart.) DK wanted a car that showcased the best of modern GT-R tuning tech but mandated that it maintain street drivability because he had no interest in running it on the dragstrip. That meant the GT-R's creature comforts like air conditioning, power steering, Bluetooth, and a full interior with heated seats had to be retained. With these stock parts, DK's car isn't some power-to-weight-watchers miracle; Tran says it weighs 3,950 pounds fully fueled. That's close to stock.
"Not close to stock is its astonishing 2,200-hp maximum output. But Tran doesn't think you should be impressed. ""Anybody with the right parts and the right tuning can make loads of power under wide-open throttle,"" he says. The team at Jotech went to extensive lengths to make this car drivable on the street. They did so by softening the dual-clutch transmission to slip in first and second gear to ease pulling away from a stop, installing two sets of fuel injectors for startup and high-boost scenarios, and even fitting a suspension lift system so DK could get the monster up his driveway. He would actually pick up his kids from school in the thing."
Of course, there's no denying that the power output is a huge engineering accomplishment. The R35's stock transmission and connecting rods are the first parts to go when you start adding power, but those bits need swapping out just to push past the 750-hp mark. To achieve the levels of power on DK's car, the Jotech team installed a 4.3-liter fully built engine in place of the stock car's 3.8-liter unit, swapped in bigger turbochargers, completely revamped the fuel system, and beefed up the transmission with stronger gears. Despite DK's disinterest in taking this car to the track, under Tran's ownership it was only a matter of time before he launched it down a dragstrip. After an encouraging series of runs on street tires, Tran mounted drag radials and recently brought the car to RaceWars in Ennis, Texas. The result? A quarter-mile run in 7.971 seconds at 175 mph.
"Looking forward, Tran understands how hard it will be to improve upon the R35 GT-R. ""The original designer already had in mind that the aftermarket was going to mod this car, and they really made everything very strong, very sturdy, and very tunable,"" he says. As far as the R36, he's hoping for more displacement and bigger turbos out of the box. ""If you're not above 700 [horsepower], you're not even in the ballpark."" On the subject of hybridization, Tran says it's definitely possible to tune a hybrid, as long as the motors are limited to the front axle; modern NSX-style hybrids with electric motors integrated into the drivetrain have a much lower power ceiling due to transmission restrictions. That said, Tran and the team at Jotech Motorsports aren't planning to slow down anytime soon."

Where Was the GT-R In Nissan's New Product Blitz Hype Video?


Text
You may have seen Nissan's newest teaser for its future lineup. If not, you're missing out. Not only does the video reveal plans for new or updated versions of nearly every vehicle Nissan makes, it also gave us our best look yet at the next Nissan Z car—presumably called the 400Z. Eagle-eyed viewers, however, might have noticed a glaring omission in the teaser: Where, oh, where, was the mighty GT-R?
It is not unreasonable to assume that, given the GT-R's absence from Nissan's high-profile roundup of upcoming products, that it might be on the chopping block. So, we reached out to Nissan for comment on the twin-turbo, giant-killing GT-R sports car's future, and whether it will survive to join the automaker's gaggle of new products. Here's what we got in response:
"""Other than what appears in the video, we have no additional information to share at this time. GT-R is and remains an important part of our brand and DNA however nothing to share at this time beyond the 2020 Model Year."""
That video covers everything Nissan is going to update until the 2023 fiscal year, we're told, which leaves two possibilities for the GT-R's place in the automaker's lineup by then. First, the GT-R may be unceremoniously killed off between now and 2023. Full stop. Goodbye. Say a few words and move on.
More likely, the sports car was left out of the new-product blitz hype video simply because it won't be receiving a major update anytime soon (or, well, before 2023). This outcome is better in that the GT-R stays alive. It's less so when you consider the now-11-year-old GT-R is growing a bit long in the tooth. Despite a steady stream of upgrades inherited over its long production run, the beastly coupe is not as potent or as capable against newer cars in its class.
We've speculated for a while about the future of the GT-R, and this simply seems to confirm the fact that, despite all our hopes and dreams, the next-gen (likely codenamed R36) GT-R is still quite some time away—but that Godzilla probably isn't going extinct, either. Hey, whenever you're ready to drop a new GT-R, Nissan, we'll be waiting. In the meantime, we're looking forward to seeing the new Z car fully uncovered.

The Awesome Daihatsu Copen Becomes a Mini GT-R Courtesy of Liberty Walk


Text
You know the Daihatsu Copen, don't you? How could you not? After all, it's the legendary two-door kei convertible known for absolutely decimating Japan's mountain roads, shaming even the most razor-sharp exotics, and being the dream ride of any true JDM fan. Aside from the fact that little of the proceeding is strictly true, the Copen is definitely an adorably awesome two-seat, two-door roadster that does in fact count as a kei car. But if you have a jones to see this teeny-tiny roadster turned into an R35 GT-R, there's only one place to go: Liberty Walk.
It was shortly after basking in the glory of the Liberty Walk R34 GT-R that we stumbled upon this rad Copen, which is one of the smallest cars Liberty Walk has ever worked on. It's certainly the cutest by far. Nearly every panel on the Copen has been reworked (or added to) in order to craft the GT-R lookalike.
The front bumper is a near carbon copy of the 2020 GT-R's—it even features the signature V-motion grille seen on most of Nissan's cars today. Riveted fender flares, a vented hood, a GT-R-esque rear bumper, and a quad exhaust setup all perfectly ape the look of the real deal. Finishing off the look is a rear wing nearly as wide as the Copen itself—it's very, very extra, but that's the point.
"We doubt much has been done to the 63-hp three cylinder engine, as kei cars are subject to strict rules and taxation regarding emissions and the size of their engines. Even so, we think this is the perfect way to stand out in the absolutely bonkers JDM car scene. Not only is it cute and sporty, it's also relatively affordable. Most of Liberty Walk's work is priced well above $10,000, but the Copen-to-GT-R ""conversion kit"" with everything included—except the car, natch—runs just $3,992 after taxes. Not bad at all for your very own Mini-Zilla."

GT-R Times Two: Nissan Builds GT-R Camera Car to Film GT-R NISMO


Text
"Why settle for Mothra when you can have Godzilla? Mothra, the fictional Godzilla monster's nemesis, in this case is the typical high-performance SUV that filmmakers often use as camera cars. In the movies, Mothra lost out to Godzilla—and it's happened all over again: Nissan skipped the usual Porsche Cayenne-based camera rig for a GT-R, its sports car that goes by the nickname ""Godzilla,"" in order to film . . . another GT-R. "
Nissan put professional stunt driver Mauro Calo behind the wheel of the camera-rig GT-R and had him play a nice game of cat-and-mouse with the beastly 2020 GT-R NISMO. Are the two cars perfect equals? No. Blame the extra weight of the camera equipment the camera GT-R has to haul around, as well as the additional bodies assigned to operate the camera gimbal, the focus puller, and choreograph the on-track dance from within the car's cabin. The GT-R's small rear seats actually are used when conducting high-speed filming. 
Still, the camera-rig GT-R is no slouch thanks to the plentiful power of its twin-turbo 3.8-liter V-6 engine, quick-reacting all-wheel-drive system, relatively low center of gravity, and sticky tires. It's the perfect camera car, it turns out, for chasing down another GT-R, NISMO or otherwise. Plus, 
it gave Nissan an excuse to publicize its aging, but still potent, sports coupe—after all, Nissan didn't really need to build the thing in order to film the GT-R NISMO. But we sure are glad it did.
