虽然设计师彼得·马斯库斯博士坚持认为，超级跑车是一辆汽车，不过这款新概念跑车外表看起来更像一辆摩托。它采用摩托引擎，车身和轮胎也采用了摩托的设计，连座位也像摩托一样前后排列。! Q3 K3 Y6 W( U+ H/ t- l; t% e

"It is a perfect engine, I love it," says Acabion's chief research officer, Peter Maskus. 3 j7 L9 E!

"As an engineer I worked for Porsche, Mercedes and BMW," says Maskus. "All those cars are inefficient; they originate from the horse-drawn carriage with their four big wheels and rectangular shape. The Acabion is the new ideal of sporting and responsible mobility." The Acabion resembles another enclosed, tandem seating, feet-forward motorcycle, the Ecomobile, although that was bulkier and powered by a BMW motorcycle engine, with a top speed of 161mph, 0-62mph in 5.7sec and a steady 56mph fuel consumption of 68mpg. 5 J& R/ I9 W H6 p( H/ J4 e3 h* L6 R& m) L5 e, i% r
