MINI has already made it perfectly clear that its new MINI Cooper John Cooper Works GP will be the fastest production car its ever built, and a new series of videos gives us a good idea of how much MINI is sweating the details.

While the original MINI Cooper John Cooper Works GP, sold only in 2006, offered improved handling, more power, lighter weight and better aerodynamics than the standard John Cooper Works hatchbacks, even that car didn’t sweat the details about aerodynamic lift and drag quite as much as the new car does.

These two videos show the development of the new JCW GP’s rear wing, as well as the level of wind tunnel testing that MINI (actually, BMW) put the car through in its testing phases. For a car not specifically designed for competition and not intended to carry a six-figure price, that’s a serious amount of effort to expend.

The net result of the JCW GP’s wind tunnel development is that the car will have six percent less drag than a MINI Cooper John Cooper Works variant, leading to a higher top speed, lower emissions and (in theory) better fuel economy.

Airflow to the engine is improved as well, while lift at the front axle (bad, because it reduces traction at speed) is reduced by some 30 percent. Even better, lift at the rear axle is reduced by an estimated 90 percent, making for a car that’s significantly more stable at high speeds.

We’re pretty sure that MINI will release videos on the rest of the JCW GP’s development, too. If they’ve paid this much attention to the aerodynamics, we can’t wait to see what they’ve done to the engine and suspension.
