Judging by these new live photos, the new BMW 6-Series Gran Coupe will likely be one of the best-looking luxury sedans on the market.Having just made its official online debut earlier this month, BMW\'s all-new 6-Series Gran Coupe seems to be a great looking luxury car.As with any unveiling, however, an automaker releases nothing but high-resolution shots of the car showing it from the best angles. And when the car debuts in the flesh, we\'re sometimes left a bit disappointed. However, we don\'t think that will be the case for this new four-door coupe.German BMW fan website BimmerToday has just released some images showing the car parked on the side of the street and when compared to the official photos from the automaker, we\'re left with no doubt that this is truly a beautiful car.Set to rival the likes of the Mercedes-Benz CLS, Audi A7, and the Porsche Panamera, the 6-Series Gran Coupe 640i will be powered by a standard 3.0-liter inline-six with 355hp. By contrast, the 650i will have a 4.4-liter V8 with 445hp. Expect for its official live debut to take place this March at the Geneva Motor Show.
