Lotus Exige with BMW M5 V10 engine swap - Bimmerfest - BMW Forums
The Lotus Exige already starts off as a great handling, lightweight sportscar. What it needed was a replacement for the Toyota power plant that was rather uninspired. A simple engine swap would have easily taken care of that, however, when you like BMW V10s, the project gets a bit more complicated.
The owner of this particular Exige really wanted the 500hp V10, from the BMW M5, in the Lotus, so the Exige was adjusted around it to make it work. The final product looks top notch and sounds great (see video below). I bet adding a few hundred extra horsepower to a 2000 lb. car makes the driving a bit more exciting as well.
