Although the horsepower numbers aren't astronomical, the torque range (peak torque is available between 2,300 and 4,900 rpm) means that the car feels eager and responsive and the power is always right there. Such a broad available torque band also means that 4th and 5th gears are quite useable for leisurely cruising – and helps balance out fuel consumption.
The nice fat grippy wheel feels good in the hands and steering is precise and nicely weighted – if somewhat lacking in feedback.
What's missing is a touch of rumble; the exhaust note is strangely subdued for a sports-tuned sedan. It's another reminder that the GS isn't a reincarnation of the brash Grand National, but rather a refined sporty cruiser for the upper-middle class professional who harbours Walter Mitty-esque dreams of performance driving.
The GS reportedly consumes 19 mpg during city driving, and 27 mpg on the highway – and that's premium fuel.
Available this fall, the GS starts at $35,310 and will be produced in GM's assembly plant in Oshawa, Ontario.
