Transaxle
One of the challenges in building a high-powered, mid-engine car is finding the right transaxle. A transaxle essentially combines a transmission, driveshaft and differential into one piece. Most street/track transaxles come from Porsche or Graziano, the OEM supplier to Aston Martin, Ferrari, Lamborghini, Maserati, Audi (R8), McLaren and others. The problem with these transaxles is that they are designed for the high-revving, flat-plane engines found in European supercars, not the lower-revving, cross-plane engines found in an American V8. A Graziano will work, but the gearing won't be right. In addition, my 1,000HP engine is capable of shredding one.
I spent the last several years working on a Ricardo transaxle, but decided to go with a Albins ST6-M.
