The Subaru engine is a 4 cylinder boxer layout, so that means that it’s 2 cylinders long, rather than the 5 on your S6. Also the block is aluminium, rather than the cast block on the Audi AAN engine. So the Subaru engine could be up to half the weight, and also the weight has less moment, as it’s all tucked in close…

Thanks. It was a free thinking build, made up as it went along, it took about a year and a half of evenings etc. We didn’t copy any other existing design, I had to look up what an Exo is...

It’s 63/37 and with two occupants it’s 57/43. Battery, fuel tank and radiator are at the rear. A spolier and rear diffuser are also fitted.
