2009 Nissan GT-R - AutoWeek






Yes, it lives up to all the hype!

The coming Nissan GT-R is a world-class supercar: Top speed of 193 mph, 0-60 in 3.5 seconds, a 473 hp, 433 lb ft twin-turbo V6 mounted in the front and driving all four wheels through a rear-mounted transaxle. Take a breath. Okay, continue. And a dual-clutch six-speed automatic you can operate via paddles on the steering wheel.

After a full day driving it on the Nurburgring, the Autobahn and up and over numerous little German country roads we can easily say this is one car that was not over hyped. It is truly a world-class supercar on par with, if not just ahead of, the iconic Porsche Turbo. (They had a Porsche Turbo on hand, too, and we thought the GT-R felt better tied down.)

But it's one thing to put a license plate on a race car and call it streetable. Chief engineer Kazutoshi Mizuno said the new GT-R was designed and engineered as an all-around, all-season, all-weather car that is comfortable to drive every day, even at normal speeds on a normal day.

During the few minutes we drove at what could be called a "normal pace" that day we'd have to say we agree with him. But given only a few hours at the wheel of this, the most highly anticipated supercar in years, we were only in "normal" mode for very brief spurts. The rest of the time we were at some level between "pushing it" and "hammering on the mutha'."

Our first time behind the wheel was on the A48 autobahn in Germany somewhere out around Koblenz or Koln or some other K-town where the German socialist government had not yet succeeded in adding those awful 120-km-hr speed limits. It was like Bonneville with elevation changes and guardrails. The only limitation out here was aerodynamic. Hence, we were obliged to go all-out whompin' fast the whole time.

Rolling right out of the autobahn rest stop where we rendezvoused with the Japanese engineering support crew, we nailed the throttle to the floor and man did the throttle respond. The 3.8-liter VR38 V6 is "an evolution" of the award-winning VQ engine family. It sits up front, with two of its six cylinders forward of the front axle and four aft. Two bagel-sized IHI turbos sit right at the exhaust manifold for quick response. The 433 lb ft of torque rails across the tach from 3200 to 5200 rpm. Peak 473 hp comes at 6400 revs.

A carbon fiber prop shaft ("Good damping and stiffness") runs back to the transaxle, incorporating the clutch, transmission and transaxle altogether. The shifting is done via a direct, twin-clutch system. One clutch handles the odd gears and another clutch handles the even ones. Shifts take 0.2 seconds. There are BorgWarner triple-cone synchronizers for all gears. Another shaft runs forward from that transaxle to send power to the front wheels. Below 25 mph the torque split is 50/50, above that, under normal driving, the split is 40/60. But it can split up to 2/98 under hard acceleration, which was what we were giving it.

Our car rode on 20-inch wheels wrapped by Bridgestone Potenza RE070s, 255/40 in front and 285/35 rears. Front suspension was upper and lower A-arms and the rear was a five-link.

It's always fun to go from zero to warp factor in a right hand-drive car using a jet-lagged left hand-drive brain, trying not to turn on the windshield wipers when you think you're hitting the turn signal.

The GT-R lists quarter-mile time at 11.7 seconds and entering the Autobahn we had no reason to doubt that. The turbo boost was, as promised, very progressive, with little or no discernable lag, just smooth, even power delivery.

Despite the late-morning hour and the mid-week day, there were still a few cars in the way. When we eased onto the 15.2-inch ventilated cross-drilled Brembo brakes from well into triple-digit speeds the car slowed without drama. But then traffic would clear out and the GT-R resumed its high velocity chase with ease.

There are three settings for the Bilstein Damptronic shocks: R, Sports and Comfort. We went out in Sports.

Top speed is listed at 193 mph but with traffic the best we could do was 176. You wouldn't try that in any country but Germany, where you can usually assume everyone else is paying attention. There was a Japanese engineer riding shotgun over on the left whom we dubbed "Bushido engineer-o" or brave engineer. He thought that was pretty funny.

While the coefficient of drag is an impressive 0.27, more than almost any production car, the GT-R also produces downforce at each axle, something very few production cars can claim.

"Cd is more important than downforce on a G35," said chief designer Hiroshi Hasegawa. "But in the case of the GT-R we have to make downforce."

At 193 mph you might appreciate that philosophy.
