3. Performance Figures
Two engines are offered in the K900. There’s a base 3.8-liter Lamba V6 that churns out 311 hp and 293 lb-ft of peak torque, figures we suspect are more than enough even for this full-figured four-door. But if you’re the sort that has to have it all you can pay a little extra and nab yourself a booming 5.0-liter Tau V8, which our test car was equipped with. It delivers a full serving of horsepower, 420 to be exact along with 376 lb-ft of twist. Both engines are matched to an eight-speed automatic transmission.
At 119.9 inches the K900’s wheelbase is identical to the Equus’ and a couple inches longer than the Genesis sedan’s. Its overall width falls just short of 75 inches, which makes it about half an inch wider than either of Hyundai’s sedans. The curb weight for a V8-powered K900 is 4,555 pounds, slightly more than an Equus.
Suffice it to say, this Kia is a large, powerful car with fuel economy to match. The model we evaluated stickered at 15 miles per gallon city, 23 highway and 18 MPG combined.
