Today, BMW->ke178 revealed the first official details of the second generation X3->ke255 prior to its debut in Paris. Let's just hope it looks better than the old one did.

Prices for the new model will be around the same as the outgoing model, as the new X3 has been completely redesigned and re-engineered. BMW hopes that the changes will help the second generation X3 sell as well as the first generation did. Chances are it will, as the BMW badge is worth its weight in gold these days. In fact, the old X3, despite being ugly as sin, has sold over 600,000 models since 2003.

The pictures of the pre-production prototype show the new X3 better than ever. It appears that the new X3 will retain the two-box silhouette and the hard edged styling that graced the old X3.

UPDATE 07/14/2010: BMW will reveal the 2011 X3 tomorrow, but today we have received the first leaked images thanks to a leaked brochure! Check them out after the jump!

“We wanted to ensure there was a clear visual link with the first-generation model. When you see it in the metal without disguise for the first time there’s no doubting it is an X3,” an insider told Autocar.

The new BMW X3->ke255 will ride on an adapted four-wheel drive system from the all-new European 3-Series->ke290. The X3 has also let itself go, with an additional 15 millimeters added to the wheelbase.

This new founded girth will help the X3 fit perfectly in between the X1->ke2474 and the X5->ke326. Amazingly, BMW engineers have increased the size of the car, but reduced the weight by 25 kilograms on the entry-level model.

Inside, the X3 is quintessentially BMW. The materials will be of good quality and the instruments and switchgear will be comparable to those found on the 5-Series->ke317. The added size helps interior space and rear seat legroom by 20mm.

Under the hood, the UK market will be getting four different engine types. Don't expect the U.S market to receive the same treatment, as the two turbo-diesels will most likely stay in Europe. The gas-powered motors will be a 3.0-liter inline six-cylinder that will produce 268 horsepower, while a 302 horsepower turbocharged 3.0-liter will also be available.

Transmissions for the UK market include a six-speed manual and an eight-speed automatic with auto stop/start technology. The latter of the two gearboxes will be the one the United States will probably be receiving.

To help the ride, BMW has equipped this new X3 with variable damping control.

Expect to see the X3 at the Paris Motor Show->ke227 this year.
