At the Amelia Island concours, the US, the facelifted BMW 8 Series as well as the M8 in coupe and cabriolet guises made their public debut.

The 8 Series will be available for UK sales in the next months with the performance-inspired M-Sport styling packages. The standard 8 Series models get a variety of BMW design elements. These include a stronger front bumper and rear diffuser, new 19in wheels, and blue calipers for six-cylinder models.

The V8 models with more power receive the same treatment, but with an additional splitter element at the front, M8-style exterior and rear mirrors, a spoiler, and a diffuser in “Dark Shadow Metallic” color. Standard equipment includes new 20in wheels as well as an M-Sport differential.

The changes to the BMW M8 range-topping models are subtler. They now have a limited range of exterior colours, including Shadow Line treatment, and newly designed M-Sport alloy wheels (20in)

The new 8 Series and 8 Series come with an optional illuminated grille, a feature that was also planned for other BMW models. It is slightly different from the pre-facelift model’s design and comes standard with the ‘Iconic Glow package. This includes an illuminated surround with waterfall lighting and each grille element. The door opens and the illumination can be turned off manually.

All new BMW 8 Series and M8 models are available with optional M emblems in red, purple, and blue to commemorate the 50th anniversary of BMW M’s establishment.

Six-cylinder models come standard with multi-contour front chairs. A 12.3-inch version of the 10.25 infotainment screen replaces the old standard 10.25 unit.

The standard 8 Series continues to offer the same engines: a turbocharged 3.0-litre straight six petrol engine that develops 333bhp at the 840ii xDrive, and a turbocharged 4.4.2-litre V8 that produces 523bhp at the M850ii xDrive. A turbocharged 4.4 litre V8 makes 523bhp at the M850ii xDrive. There’s also a turbocharged 3.0-litre turbocharged six-cylinder diesel with 335 xDrive with 335bhp at the 840d xDrive. All models are standard four-wheel drive.

While the M8’s twin-turbocharged, 4.4-litre V8 continues to produce 592bhp as a standard, the M8’s more powerful Competition car, which is sold in the UK, produces 616bhp and a 0-62mph speed of 3.2 seconds.
