BMW and M wouldn't be teasing, let alone fully showcasing the F10's powerplant. It's all about suspense and anticipation, it wouldn't make sense to let out the secret this early.

In my opinion, this vehicle is a confirmation that BMW and M have decided against using an updated V10 for the upcoming M5. This engine was probably one of the prototypes that was developed, but now (my guess and my opinion) that BMW have opted for the V8TT, they just released this M5 'CSL' simply because it coincides with the 25th Anniversary for the M5.

It might just be a last swang-song for a naturally aspirated M5...and the awesome V10 that will soon be replaced for the F10 (IMO again).

Think about it...if this M5 'CSL' was really in the works for a while, you'd think they at least unveil it at some autoshow, and give it a tad updated styling, just to do a proper and deserved 25th Anniversary M5...but the low-key media release, and even the lack of quality in info and photos shows that this wasn't planned much.. just thought of 'last minute' since they had this barnstorming updated V10 sitting in the testing facility with no future.

Details, quickly please! I’m slobbering over this new BMW M5 already.

Let’s start with the engine. As if the 500bhp/384lb ft 5.0-litre V10 wasn’t incredible enough, BMW’s M Division has stroked it out to 5.5-litres. Add in a new carbonfibre manifold and the outputs have risen to over 580bhp and nearly 400lb ft.

And to cope with that extra power BMW has junked the sequential-manual gearbox and brought in a beefed-up version of the M3’s seven-speed dual-clutch M DCT ‘box.

Inside the gearbox is linked to a pair of paddles, while the driver and front-seat passenger sit in new carbonfibre-backed buckets. There’s also a new carbonfibre roof – that cleaves a claimed 50kg of the E60 M5’s 1855kg kerbweight – and the rear seats have been junked. There’s also been a tweak to the specification of the adaptive suspension.

Bar M Division’s triple-stripe colour scheme, and some stickers celebrating 25 years of the M5, this one-off looks little different to the standard car. The only visual clue is the offset number plate, which makes way for an new intake that feeds air to the extra oil cooler.

Expect this special E60 M5 to hit 62mph in close to four seconds, and easily top 200mph. We also hear it’ll lap the Nurburgring in under eight minutes, a comfortable 20 seconds or so quicker than the standard car.

But BMW isn’t going to produce this, so we’ll just have to wait for the new twin-turbo V8 M5.
