BMW's new 8 Series has arrived with the M850i making its dynamic debut at the Goodwood Festival of Speed hillclimb! Let's explore both the M850i and the new M Performance Parts Concept M2 and experience a flat out blast to get a feel for what it's like.The M850i sits alongside the 840d for the current Coupe line-up, with a teaser for a future M8 having been shown in Gran Coupe 4-door form - no doubt that will arrive in the near future. In the M850i we have a 4.4l twin turbo V8 with 530hp, linked to the xDrive all wheel drive system. On the inside there have been significant changes and we can take a first look through some of these while on the move.Additionally, BMW made a release of the M Performance Parts Concept at the show; based on the original M2 with a whole host of carbon fibre components on the exterior and interior. I for one am looking forward to a full drive of the new M850i in future!
