This weekend we’ve witnessed the launch of the 2012 Bmw 6-Series Gran Coupe, a new car that introduces the Bavarian manufacturer into a new segment, a segment launched by the Mercedes-Benz CLS. The war is now starting, as everyone will ask now which car would be the perfect choice for them: the Mercedes-Benz CLS, the Audi A7 Sportback or the recently launched Bmw 6-Series Gran Coupe.
I think that when you are choosing a car, you look first at the engines, right? These days, every manufacturer works hard to have fuel-efficient engines but also powerful engines, especially German manufacturers. We’ll start with the petrol engines: the Bmw 6-Series Gran Coupe comes with a 3.0-liter six-cylinder in-line petrol engine delivering 320 hp (640i Gran Coupe), while the Audi A7 Sportback features the well-known 3.0 TFSI V6 engine delivering 300 hp; the Mercedes-Benz CLS offers a 3.5-liter V6 engine delivering 306 hp.
The 3.0-liter engine can push the 6-Series Gran Coupe from 0 to 100 km/h (62 mph) in 5.4 seconds, while the Audi A7 is pushed by its V6 in just 5.6 seconds… still, the Mercedes-Benz CLS is the slowest, with its 6.0 seconds. As expected, all the models have the top speed electronically limited to 155 mph or 250 km/h.
Average fuel consumption: 7.7 – 7.9 litres per 100 kilometres (30.5 – 29.7 mpg imp) for the Bmw 640i Gran Coupe, 6.8 liters for the Mercedes-Benz CLS (34.5 mpg) and a 6.6 – 8.2 (combined) liters (35 – 28 mpg) for the Audi A7 Sportback. For those who want smaller engines, the Audi A7 Sportback with the 2.8 TFSI engine with 204 hp and a fuel consumption estimated at 6.5 liters per 100 km or 36.1 mpg.
Now, here are the most powerful versions: the Bmw 650i Gran Coupe comes with a 4.4-liter V8 engine with 450 hp and can sprint from 0 to 100 km/h (62 mph) in 4.6 seconds; the standard Audi A7 Sportback doesn’t come with a more powerful engine, but the Audi S7 Sportback does as this model is powered by the new 4.0 TFSI V8 engine delivering 420 hp and capable to push to 100 km/h (62 mph) in 4.9 seconds; the Mercedes-Benz CLS comes with a 4.6-liter V8 engine delivering 408 hp and able to push the car to 100 km/h (62 mph) in 5.1 seconds.
The Bmw is expected to deliver a fuel consumption of 9.2 liters per 100 km (25.5 mpg), the Audi delivers 9.7 liters per 100 km (24.25 US mpg), while the Mercedes-Benz will deliver 9.0 liters per 100 km or 26 mpg. The most interesting engines will be the diesel engines: the 640d Gran Coupe comes with a 3.0-liter six-cylinder in-line diesel engine delivering 313 hp and capable p push the car from 0 to 100 km/h (62 mph) in 5.4 seconds; the Audi A7 gets a 3.0-liter V6 TDI engine delivering 313 hp and capable to sprint from naught to 100 km/h (62 mph) in just 5.4 seconds; the CLS gets a 3.0-liter V6 diesel engine with 265 hp and can sprint to 100 km/h (62 mph) in 6.2 seconds.
The average fuel consumption of the 640d Gran Coupe is 5.5 – 5.7 litres per 100 kilometres (42.7 – 41.2 mpg), while the Audi delivers 5.5 liters (42 mpg); the CLS has a fuel consumption of 6.1 liters/100 km or 38 mpg. As expected, in terms of design, you have to choose a car with your soul, you have to know what it fits you better. The Bmw 6-Series Gran Coupe look impressive, the Audi A7 Sportback is that kind of car that doesn’t draw the attention but can do anything for you while the Mercedes-Benz CLS leaves you speechless at the first visual impact.
The same problem comes with the interior: all the vehicles are able to deliver everything you want from a car. All the vehicles offer high quality interiors and can be customized in every way that the customer wants. Regarding the price, all the cars can be bought for around €60,000 or $80,000 but don’t forget that if you want a car with all the optional systems and features cost a lot and the mentioned prices are just the starting bid.
