Where the BS Stops
At the test track the 2010 Hyundai Genesis proves itself a worthy entry into the sport coupe segment by giving the pricier
Infiniti a run in several categories. First, the Genesis tips the scales at just 3,488 pounds — 221 pounds lighter than the G37. Porkiness has long been a valid gripe about any car built on Nissan's FM platform and the G is no exception.
But being lightweight didn't help the Genesis coupe accelerate as quickly as we had hoped. The Genesis hit 60 mph from a standstill in 6.4 seconds (6.1 seconds with 1 foot of rollout like on a drag strip) and went through the traps at the quarter-mile mark in 14.5 seconds at 97.9 mph. That's considerably slower than the G37's 5.7-second run to 60 mph (5.4 seconds with 1 foot of rollout like on a drag strip) and its quarter-mile performance of 13.9 seconds at 101.4 mph.
Accelerating the Genesis quickly can be tricky because of a drivetrain protection feature built into its engine calibration. Shift the Genesis coupe aggressively at redline and you'll occasionally experience a power cut in your target gear which lasts 3 seconds.
The problem is exacerbated by the car's tachometer, which doesn't keep up with the engine speed in the first few gears, so it's too easy to run the engine to its 6,800-rpm maximum speed (redline is 6,500 rpm). Hyundai says the drivetrain protection is triggered at 6,800 rpm, but once it intervened, we experienced a power reduction in the next gear at much lower engine speeds. Run this V6 to the rev limiter in any given gear and it will hang there comfortably. But if you shift hard and quickly at the indicated redline, you'll occasionally be punished with that cut in power.
Hyundai is considering a new calibration, but there are cars going on sale that incorporate this 3-second power intervention, a feature that can punish drivers at engine speeds well below redline. Some people won't notice it, but to others it could be a deal breaker in the purchase of a Genesis 3.8 coupe.
