Paired with a smooth automatic transmission driving the rear wheels, it can accelerate from 0 to 60 mph in around 5.5 seconds and has an electronically limited top speed of 155 mph (250 km/h). At 4,820 mm long and 1,855 mm wide, and weighing approximately 1,700 kg, it delivers a strong road presence while maintaining grand touring comfort, which is further enhanced with a refined BMW E63 Exhaust System.

Staying Ahead: Competitive Edge and Market Position

With its strong mid-range torque and refined V8 power delivery, the E63 645Ci competes confidently with rivals such as the Mercedes-Benz CL-Class and Audi A5 Coupe. Its grand touring platform makes it an excellent base for performance-focused upgrades, particularly to the exhaust system where the character of the V8 can truly be transformed into a deeper and more engaging driving experience.

To enhance the driving experience, the focus was placed on improving the exhaust system to unlock the full sound potential of the naturally aspirated V8. The work carried out refined the exhaust flow and reduced restriction, allowing the engine to breathe more freely and deliver a smoother, more responsive throttle feel. The result is a noticeably deeper tone at idle and a more aggressive V8 roar under acceleration, giving the car a stronger presence on the road while maintaining comfort for everyday driving.

The upgrade transforms the overall character of the BMW E63, making the sound more engaging and enjoyable without introducing unwanted drone, perfectly complementing the grand touring nature of the vehicle.
