The BMW 635 blends classic grand tourer style with modern performance and comfort. Known for its powerful presence and long-distance capability, the 635 stands out for drivers who value refined motoring with a sporty edge.
The BMW 635, especially the iconic 635d coupe (produced from 2007-2010 as part of the E63/E64 generation), is designed for drivers seeking luxury, space and effortless high-speed cruising. It builds on the rich heritage of previous 6 Series models, such as the original 1980s 635CSi, bringing updated safety, comfort and diesel efficiency to modern driving. Compared with rivals like the Jaguar XK and Mercedes CL, the 635 focuses on a balanced ride, brilliant engine performance and superior practicality. Recent models boast comfortable seats, a big boot for luggage and strong technology– making them ideal for relaxed commutes or grand touring holidays.

Rear seat space is tight for adultsRunning costs can be highNot as agile as smaller sports coupesThe BMW 635 is fitted with advanced safety features for its era. Expect anti-lock brakes, traction control, multiple airbags, stability control and Isofix child seat mounts. Parking sensors and strong headlights often come as standard. Higher trims may have extra driver aids.
Most UK BMW 635s refer to the 635d, which uses a 3.0-litre twin-turbo diesel with 281bhp, automatic transmission and rear-wheel drive. Classic models like the 635CSi feature a 3.5-litre straight-six petrol. Petrol engines were available in earlier generations or in high-performance versions.
Standard kit includes climate control, leather upholstery, electric seats, cruise control and a high-quality audio system. Many models feature satellite navigation, Bluetooth, parking sensors and automatic lights. Top trims add heated seats and upgraded sound systems.
The 635d diesel can achieve around 40mpg combined, with some official figures even higher. Petrol models are less efficient – expect mid-20s to low-30s mpg, depending on driving style, engine and model year. As always, mileage may vary in daily use.
When considering a used BMW 635, check for a full service history, especially for automatic gearbox servicing and diesel particulate filter (DPF) issues. Inspect electronics, suspension and recall status. It’s wise to book The AA Vehicle Inspection for added peace of mind.
The BMW 635 is generally reliable with proper servicing. The diesel engine is robust but can incur high repair costs if not maintained, particularly regarding the DPF and turbo. Routine care and specialist attention help ensure low-stress ownership for years.
