V12 Prototype in 3 Months

This V12 was designed, prototyped, and released for manufacturing in an incredibly short time period. The initial drawings were completed in 5 days, an 8 cylinder prototype was ready in 8 weeks, and the 12 cylinder prototype were done in 12 weeks. Two months after the prototypes were approved, orders totalling 22,500 across multiple manufactures were released. 22,478 engines were built in a 2 year time slot, that included design, prototype, and approval.

Its power to weight ratio 0.53hp/lb, roughly midway between a 80’s Chevy Celebrity and a Mazda RX-8 which while not stellar, isnt too bad either.

It cranked out 400hp.

No CAD tools were used despite the incredily short design and production time frames. In a similar vein, there was no use of stereolithography, or even CNC machining centers during design or production.
