Comment number 1 in backfires:
I thought of these same cars to compare with.12.9 at 111 mph out of a rear drive 4004 lbs car with a claimed 365 hp and 376 tq?? It's either underrated by 10-12% or this pre-production model is a ringer they gave out to journalists to use so they'd get great numbers to increase it's sales when it goes on sale. I'd like C&D to retest a production model to get it's times, if they can closely reproduce those numbers in similar conditions on the same track, then this car is underrated in the power department. If not, it was yet again another deceiving game that an automaker did with the pre-production model.
**Edit: After perusing a few stats in the luxury car comparison test C&D referenced, the Stinger got the exact same 1/4 mile time as the Cadillac CTS VSport that weighs almost identical in weight to the Stinger, also has 8 speed auto, similar overall gearing, but the Cadillac has 420 hp and 430 lbs ft of torque. And in the "top gear" rolling acceleration the Stinger even out accelerates the CTS by a smidge.
Another example is the Chevy SS sedan. It also achieves the same 12.9 @111 mph times with a 415 hp V8 in a car that weighs about 50 lbs lighter than the Stinger.
So again, this pre-pro Stinger is a ringer that the production models won't replicate, or Kia is vastly underrating this car's power output by the 10-12% I suggested above.
