Since it arrived on the U.S. scene for the 2009 model year, the Nissan GT-R has seen continual improvements. For 2017, the Japanese supercar gets even more updates. While most updates focus on aesthetics and comfort, Godzilla also gets another power boost for its latest refresh. Here is a look at the Nissan GT-R's performance evolution through the years.

When the R35-generation Nissan GT-R arrived in 2009, its twin-turbocharged 3.8-liter VR V-6 was rated 480 hp and 434 lb-ft of torque. A six-speed dual-clutch transmission combined with the automaker's ATTESSA E-TS all-wheel-drive system and advanced electronics routed power to all four wheels. The first R35 Nissan GT-R we tested hit 60 mph in 3.2 seconds and finished the quarter mile in 11.6 seconds at 120.0 mph. More than a one-trick-pony, the GT-R lapped the figure-eight in 24.3 seconds and pulled 0.97 g average around the skidpad. Those numbers were mighty impressive for its day, but the GT-R wouldn't stop there.

The GT-R received its first power boost in 2010 and now made 485 hp. In 2011, Nissan also added a new transmission control unit and updated the suspension tuning, which made a noticeable difference in handling. The figure-eight lap dropped to 23.7 seconds, while the skidpad number climbed to 1.03 g. In 2012, the GT-R got a massive power boost, which increased horsepower by 45 and torque by 14 for totals of 530 hp and 448 lb-ft, respectively. Acceleration and handling both improved, as did handling.

Not about to leave well enough alone, Nissan increased horsepower another 15 to 545 hp and torque by 15 to 463 lb-ft for the 2013 model year. The GT-R also gained revised suspension tuning. Our long-term 2013 Nissan GT-R Black Edition now accelerated to 60 in 2.8 seconds. The figure-eight time dropped to 23.0 seconds flat.

A new Track Edition was introduced in 2014 and ditched the rear seats in search of weight reduction. The new model featured a stiffer suspension and new Dunlop SP Sport Maxx summer tires. In 2015, Nissan introduced the hardcore GT-R NISMO model with even more power and wilder aerodynamics. While lesser GT-R models still make 545 hp and 463 lb-ft, the GT-R NISMO makes an astounding 600 hp and 481 lb-ft. That's an increase of 55 hp and 18 lb-ft. In testing, the 2015 Nissan GT-R NISMO posted a best acceleration run of 0-60 mph in 2.9 seconds and a quarter mile in 11 seconds flat at 126.6 mph. The figure-eight time dropped to just 22.9 seconds.
