2009 Infiniti G37x S Sedan Performance and Specs. Driven by Motor Trend

As a general rule, adding weight to a car is to be avoided if at all possible, as it's a detriment to performance and fuel economy. Adjust your goals, though, and it becomes a reasonable tradeoff. Take for example the 2009 Infiniti G37x S, an all wheel-drive version of Infiniti's star entry-luxury car.

If you skip straight ahead to the numbers, you'll find the G37x S is heavier and slower and doesn't handle quite as well as the G37 S sedan, but the numbers don't tell the whole story. Infiniti clearly designed its G37x cars to outperform their rear-drive G37 counterparts in less-than-ideal weather conditions, such as those in cold weather states during the winter.

While the all-wheel-drive G37x S would likely fair considerably better on snow-covered roads than the standard G37 S, on hot, dry asphalt, it falls slightly behind. The only major difference between the 2009 G37 S sedan we tested late last year and the G37x S sedan we just tested is the inclusion of Infiniti's "Advanced Total Traction Engineering System for All Electronic Torque Split" all-wheel-drive system lifted from Infiniti's crossovers, along with the seven-speed automatic transmission. Both cars featured the same 328-hp, 3.7L V-6 producing 269 lb-ft of torque and both were equipped with the optional Sport package.
