BMW 640i Gran Coupe (F06)

The 2012 to 2018 era produced a particular kind of GT, and the BMW 640i Gran Coupe (F06) shows where that moment sat in a 600-car catalogue. Its most unusual position is not at the top of a performance table, but in a category of its own: it is the least expensive inline-6 car in the catalogue. At £22,000 used, it places 561st of 600 cars by price, yet it still brings a configuration shared by only 33 cars in the collection.

That combination explains the character of the 640i Gran Coupe. It is a GT built around the pairing of a turbocharged inline-6 and rear-wheel drive, a layout used by just 9 cars in the catalogue, with only 11 combining turbocharging and inline-6 power. The 3.0-litre engine delivers 316 bhp and 450 Nm, figures that place it 490th for power across all 600 cars. The numbers show a car designed less around outright dominance and more around a particular balance of format, engine layout and accessibility within a high-end collection.

Its acceleration remains part of that story. A 0-100 km/h time of 5.5 seconds places it 505th of 600 cars, meaning it is faster than 95 cars in the catalogue. The 250 km/h top speed ranks 414th. These positions frame the 640i Gran Coupe as a car that sits outside the extremes, offering a measured GT experience rather than chasing the highest numbers available.

The German connection is also central to its place in the collection. Germany accounts for 197 of the 600 catalogued cars, and BMW contributes 48 cars to the catalogue. The 640i Gran Coupe adds another interpretation of what a German GT can be, with a 4/5 seater hatchback body style and rear-wheel drive layout supporting its role as a practical grand tourer.

With a cost of £70 per bhp, the 640i Gran Coupe presents a notable equation: an inline-6, turbocharged, rear-wheel-drive GT from BMW for an accessible position among the catalogue’s performance cars. Its presence changes the shape of a dream garage. Without it, the collection loses one of its rare combinations of inline-6 engineering and lower entry price. With it, the garage gains a car that represents a specific era of GT thinking, where balance mattered as much as the headline figures.
