2010 Hyundai Genesis Coupe V6 Track Retest
A couple weeks ago we ran a full test on the 2010 Hyundai Genesis Coupe V6 Track. It ran respectable numbers, but not the kind of times we expected from a 300+ horsepower, rear-wheel drive coupe of its size.
Hyundai was disappointed to. So they went through the car following our track session looking for answers. What Hyundai's engineers found was a rear wheel alignment that was off spec and worn front tires paired with new rears.
Another problem was the car's ECU. It was programmed for damage control, not 0-to-60mph runs, so it was cutting power when it was needed most. We complained about this system in the test article and were sure the car would accelerate quicker if the damage control system was backed off a bit.
Hyundai agreed and made a running change to the ECU that keeps it from cutting in during fast shifts. Hyundai is fast at work reflashing all the cars now at dealers and at the port (If you're one of the few that has already bought a Genesis Coupe, call your dealer and they'll reflash your car for free). They also offered to mount some new tires and made sure they were pointed straight too.
Then they asked if we wouldn't mind running the car again. We said yes.
