相比“布加提威龙”巨大的16.4升引擎而言，超级跑车使用的引擎明显小巧许多，容量只有1.4升，耗油量也要小得多。超级跑车使用一个容量90升的油箱，在每小时100公里的时速下，跑车能够行驶至少2400公里。 3 }5 D/ X( L7 o" w ; p) G7 n6 P/ F/ F 超级跑车设有一对辅助轮。跑车全速行驶时辅助轮被挂起，当跑车慢速行驶时，液压臂会将两只辅助轮放下，以维持车体平衡。超级跑车还拥有一部2千瓦的电动引擎，以便在低速行驶时替代柴油引擎，从而达到进一步节省燃料的目的。 1 e) l* @" q4 `: ^6 I 1 w6 e" l2 U0 A. |) K4 g 像摩托车的跑车 / S1 @' E, Z8 M6 h8 p.

"It is a perfect engine, I love it," says Acabion's chief research officer, Peter Maskus. ; ^$ b+ \; a& F8 J J$ p' y
When it goes on sale in 2009, the Acabion GTBO 70 will only be capable of 150mph, but its maker claims the 300kg vehicle is the world's most exclusive; production from 2007 to 2011 is limited to 26 examples. 4 U X$ x3 N0 h+ Q"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. 6 A2 s$ f; ]) D!
