Earlier today we showed you a sneak peak at the 2011 Cooper, now it’s time to take a look at the Cooper S once again courtesy from our good friends at Bigblogg. We’ve already seen a few revealing spy photos of the car but these are the first official photos (leaked from a German magazine or German brochure) that show the car completely uncamouflaged.

In the previous post we saw Spice Orange (for the second time) and here we see the R57 Cooper S Convertible finished in Ice Blue.

As you might expect the front end seen here (on an R56) will be carried over completely to the Cooper S versions of the R55 Clubman and the R57 Convertible.

With this refresh comes new engines, new wheels, more steering feel, new colors (inside and out) and new packages. So far it’s a pretty compelling package in our eyes and definitely worth waiting for if you want a new MINI.

As has been mentioned many times over the past six months on MotoringFile, the 1.6L turbocharged powerplant at the heart of the Cooper S will thoroughly revised. Yes there’s more power, but lets focus on efficiency first. The R56 MCS will reach the similar if not the same mpg on the highway as the 122 hp Cooper thanks to the addition of Valvetronic. Not only does MPG go up but CO2 levels are only 3 grams off the Cooper (140 gm to 143) despite the turbo and the extra 60 hp. The MCS sees all the same updates that the Cooper gets but with the major addition of fully variable valve train (Valvetronic as BMW calls it) along with refinements of friction point throughout the engine. The result is an increase of around 10hp for approximately 182 hp (final US figures are forthcoming).

Valvetronic gives the Cooper S the ability to rev quicker, deliver more power yet achieve better miles per gallon. A win win by all accounts.

And that cold start issue on the R56 MCS? It’s eliminated with the new engine and the addition of Valvetronic.

You can see the entire list of engine specifications for all models of the 2011 Cooper S below. However keep in mind that these are European figures. US data has yet to be released.

The 2011 MINI will quite a few other small revisions such as xenon headlights that swivel with the steering and auto-dip passenger side mirror for parallel parking. We’ll be detailing more of the smaller changes soon however if you can’t wait you can find dozens of articles on many of the updates within the 2011 LCI section.

The new models will go on sale in September of 2010. Dealers and the online configurator should have information sometime in July or early August.
