They say it gets great mileage because of "torque multiplication"?!?! You mean it has a transmission!!! Wow!! What a great idea!
I found the mfg web site. GM 6.6 liter diesel. 375hp with 570lb/ft torque at 1800 rpm. And yes, the "torque multiplication" they are talking about is an 8 speed gearbox with very high ratios. Still a pretty cool looking car. Interesting idea, to put a big diesel engine in to a sports car. http://www.trident-vehicles.co.uk/index.php?option=com_content&task=view&id=30&Itemid=41
