Road - Crazy Horse Saloon

BMW has revealed details of its soon to be available "fastest and most powerful BMW M production car" - ever. Their quotation marks, not mine!

As you would expect, the BMW M5 CS will be searingly fast yet eminently usable on a day to day basis. This limited edition model offers genuine 'supercar' performance  – 0 to 62 mph in 3 seconds and a blistering 124 mph from rest reached in 10.4 seconds, and onwards to an electronically limited top speed of 189 mph.

It might even be regarded as the ultimate 'Q' car. There are no big wings and no tarmac scraping airdams. Just slight bulges over the  275/35 R 20 Pirelli P Zero Corsa track tyres at the front and 285/35 R 20 at the rear.

Well hidden from view is the nuclear powerplant under the bonnet. The twin turbo 4.4 litre V8 engine delivers a stonking 635hp. Add that to the lightweight design, bespoke chassis tuning and the xDrive system with an intelligent Active Differential.

Machine management comes with a choice of three modes - Efficient, Sport or Sport+ . For added enjoyment there is an M Sound Control button! This changes the engine note in the Sport+ setting, but it can be used at any time to soften the car’s acoustic presence – for example when driving through a residential area.

Carbon ceramic brakes are fitted as standard with six-piston, fixed-calliper units at the front and single-piston floating callipers at the rear. These are 23 kgs lighter than the brakes on the BMW M5 Competition!

Inside the car there are four lightweight individual bucket-style seats, with the outline of the Nürburgring circuit imprinted on the head restraints. The  heated front seats are electrically adjustable for height, tilt, seat cushion length and backrest angle, while the backrest width can be altered pneumatically, so there's no sacrifice with regard to personal comfort.

Alcantara is used to wrap the steering wheel with carbon fibre paddles behind it.

A 12.3 inch central display provides access to driving dynamic systems allowing drivers to swiftly access the various Road and Sport settings. Keeping the M Mode button pressed engages TRACK mode which also brings up M View in both the instrument cluster and the Head-Up Display. The 12.3‑inch instrument display adds an M-specific rev dial, shift lights, digital speed readout and the gear currently engaged.

Drivers can also choose to view additional information including coolant temperature, charge pressure, tyre condition and longitudinal/lateral acceleration in the instrument cluster.

When M View is active, a rev counter with colour-coded warning zones appears in the Head-Up Display alongside shift lights. Navigation instructions, distance warnings, current gear, vehicle speed and any speed limits or overtaking restrictions detected by the Speed Limit Info system are also displayed here.

And there's more. Pressing the Setup button brings up a menu for programming an individual configuration for the powertrain and chassis options. This allows the driver to choose his or her own different settings for the engine, suspension, steering and M xDrive system.

Variable Damper Control (VDC) offers a choice of Comfort, Sport and Sport+ settings so that this track monster can be tamed (temporarily) for the weekly shop or school run. Then at  weekends you can just poke the beast with an electronic stick and go have fun - but only at a licensed track.

Now, if I just had a spare £140,780, or a JCB backhoe to dig a cash machine out of a wall.
