This sleek concept has three distinct angles: a front crease by the fender, rear haunches, and a slanted roof. All three come together for an unusually appealing design. The 3.0-liter V6 engine produces 375 horsepower and 332 lb-ft of torque. (That’s about 125 horsepower per liter.) An experimental “hybrid boost” system increases output about another 94 horsepower: Just push a button on the steering wheel called “push to pass.” The top speed: 186mph. Acceleration form 0 to 60 is fast, at just 4.4 seconds.
