The BMW E63/E64 is the current model of the BMW 6 Series of luxury coupés, introduced in Autumn 2003 in Frankfurt Motor Show by German car manufacturer BMW. It comes as either a coupé or cabriolet (convertible) and in several engine variants ranging from a 3 litre straight-6 to 5 litre V10 in the M6 model.

In 1989 the original 6 Series was supplanted by the more expensive and higher performance 8 Series. In late 2003, the 6 Series was reintroduced as a 2004 model, with coupé and convertible versions based on the BMW E63 and BMW E64 platforms, respectively. The E63/64 itself is based on the BMW E60, the latter which forms the current iteration of the 5 Series saloon.

Engines
These two models are each available with either a 3.0 L (2996 cc) straight-6 N52 engine producing 190 kW (258 PS; 255 hp) at 6600 rpm and 300 Nm (220 lb·ft) of torque from 2500–4000 rpm (in the 630i), a 4.4 L (4398 cc) V8 making 245 kW (333 PS; 329 hp) and 450 N·m (330 lb·ft) of torque at 3600 rpm (in the 645Ci).[1] or In Europe a diesel engined variant (the 635d) is available. This has the same 3.0 L6 twin turbo diesel engine as in the 535d and 335d. It has 286 hp (213 kW) at 4400 rpm and 580 Nm (430 lb·ft) of torque available at 1750 rpm. The 645 models have now been phased out in the favour of the more powerful 650i and they are now called 650i Coupé and 650i Cabriolet. (no Ci any more in the naming) The 630i is not available on US market. It is available in Europe as both Coupé and Cabriolet.

The V8 in the 645Ci is the N62 engine, the same powerplant used in the 545i and 745i, with BMW's Valvetronic variable valve timing system. This is an all aluminium engine with 4 valves per cylinder. This 6-Series comes with either a 6 speed automatic transmission or a 7 speed SMG sequential gear box. For the 2006 model year, BMW remodelled the 645Ci as the 650i. The reason for this change was the increase in engine displacement. A manual transmission is also available.

Various auto tuners offer after market products for the BMW E63/E64 that include improved engine software, throttle bodies, and exhaust sets that improve horsepower through the power band.

Styling
Unlike that of the new 5 Series and 7 Series models, the styling of the new 6 Series has generally received a warm welcome from the BMW community-except, largely, owners and enthusiasts of the E24. The new 6 Series was designed to look like a shark, and many have acknowledged the resemblance. The controversial rear styling is considered to work somewhat better on the shapely E63 than on other BMWs.

Autumn 2007 update (LCI)
In the autumn of 2007 BMW debuted an updated BMW 6-Series Coupe and Convertible. They feature new LED turn signals in the headlights, slightly restyled rear tail lamps with an LED turn signal, and a redesigned third LED brake light that has been enlarged and moved to the top of the bootlid.

M6
In 2005, an M6 version of the new 6 Series was introduced. It shares the E60 BMW M5's engine and transmission (500 hp). In the third quarter of 2006, BMW announced the M6 convertible as an upcoming 2007 model. The 2008 model year M6 Coupé and Cabriolet both benefited from the standard 6-Series refresh during the Autumn of 2007.
