BMW has already revealed its all-new 5 Series sedan and wagon, as well as the M550i. As expected, they're mighty impressive. But what we're anxious for is the next generation BMW M5. Fortunately, we won't have to wait much longer, because that new high-performance sedan is expected to arrive later this year at the Frankfurt Motor Show. Before that happens, we've compiled everything we know about the next M sedan so far, from its expected power output, performance and whether or not it'll offer a manual. Let's start with what'll be under the hood.

Sources have claimed there'll be a reworked version of the current M5's twin-turbo V8, producing a total of around 600 hp. This will put the new M5 directly in line against the new Mercedes-AMG E63 S, which has 603 hp and 627 lb-ft of twist from a twin-turbo V8 of its own. The M5's power will be directed to all four wheels through an eight-speed automatic. Let's talk about that. Every previous M5 has RWD, but that's changing. Why? Partly because Audi's Quattro AWD system features across its lineup, and also to expand M5 ownership to those living in regions with snowy winters. However, the new M5 will still feature M Dynamic Mode, which decouples the front differential, enabling drivers to send all 600 horses to the rear wheels.

And no, a six-speed manual won't be offered – even in the US. The take rate, unlike in the M3 and M4, simply isn't high enough. In fact, the six-speed manual in the current M5 was developed specifically for the US, and that wasn't exactly cheap to do. As far as performance goes, expect a 0-60 mph time of less than four seconds, compared to the current car's 4.4-second sprint. Thing is, the new M550i hits 60 mph in 3.9 seconds, so the new M5 must improve upon that even further. Performance, as always, is highly dependent not just on engine output, but also vehicle weight, but the 2018 M5's weight won't be dramatically different.

Although BMW is utilizing plenty of lightweight aluminum, high-strength steel and carbon fiber, reports indicate the vehicle will tip the scales at around 4,000 pounds, compared to the current car's 4,122 pounds. Why so little difference despite the greater use of lightweight materials? Because of that all-wheel drive system. Design wise, expect the usual M styling add-ons we've come to expect inside and out, meaning beefier wheels, unique front and rear end styling, and plenty of M badges. We expect more details to continue popping up throughout the summer, just ahead of the 2018 BMW M5's September debut.
