According to BMW, the car is built on a,
"Z8 chassis and has a 4.4-liter V8 and six-speed automatic transmission... the fabric skin — polyurethane-coated Lycra — is resilient, durable and water resistant. It's stretched over an aluminum frame controlled by electric and hydraulic actuators that allow the owner to change the body shape."Right here is where I would put my own spin on the quote, but I'm not sure what they just said because I fell asleep three words into it. Honestly, I can't tell the difference between a horse-drawn cart and a Maserati, so .... who cares. It does look cool though.
Plus, if you got into a car crash, you could take it in to a tailor instead of a body shop. Bling bling! Now that's a money-saver. And, it's one step closer to an awesome sailboat-car. For all those James Bond moments in your life.
