Here are the latest pictures of the next-generation BMW 6 Series spied with much less camouflage than ever before. We can see more design details, including some lines on the doors as well as the undisguised soft top. BMW is sticking to that roof type for its biggest grand tourer.

Previous spy activity revealed details such as a centrally-mounted brake light and a larger BMW emblem at the rear.

It is expected that the car will share most engines with the 5 Series, which means buyers can pick from the 4.4-litre V8 with 300kW (402 bhp/ 408 PS) and the 3.0-litre twin scroll turbo worth at least 225kW (302 bhp/ 306 PS) among others. The M6 is said to benefit from a more powerful version of the 4.4-litre twin turbo. The company's new 8-speed automatic is expected to send power to the rear wheels.

Look out for the all-new 6 Series some time in 2011, following public debuts at several international auto shows.
