The end result is a 450-hp luxury tourer with 445 lb.-ft. that weighs in at a scant 3058 lbs and will run up to 60 mph in four seconds flat. Throw in a 190-mph top speed, 60-to-0-mph braking in 107 feet, 1.03 g on the skidpad, and 16 mpg city and 26 mpg highway, and the $99,995 price tag doesn't look quite so bad.
