Michigan-based Pratt & Miller Engineering, a powerhouse in sports car racing, has been contracted to engineer and prototype the all-new machine. The liquid-cooled V4 will deviate from typical high-performance protocol by utilizing a single, chain-driven camshaft nestled in the valley of the Vee like an American V8, with pushrods and two valves per cylinder. Design benefits include compact cylinder heads, simplified maintenance and, most importantly, useful power. Pratt & Miller created the Le Mans-winning GT1 Corvette C5-R and C6-R racers-also single-cam, pushrod, two-valve designs- which should answer any questions regarding the new engine's performance and durability. Targeting 140 horsepower at 7800 rpm and 120 lb.-ft. of torque at 4500 rpm, the fuel-injected Motus MST-01 aims to provide strong performance across a wide rev range, with a pleasing countenance that higher-revving fours lack.
