It may have a static stance to die for, but Mstyle’s tuned BMW M4 F83 demo car is a whole lot more than just a good looking convertible. Just wait till you see and hear it driven in anger!
620bhp. A figure which fifteen years ago was still a thing of dreams to all but owners of the most hyper of hypercars. But that’s exactly how much firepower is racing through the sci-fi veins of this cutting edge BMW M4 here – tuning house Mstyle’s latest demo car aimed to showcase exactly what the firm is capable of – don’t you just love the 21st century?!
You might remember the Essex-based company’s previous demo car: a V8 M3 which was also a white, convertible affair (owner Paul’s self-confessed spec of choice). While that one mainly focused on looking pretty, it only takes one ride in this new addition to the fleet to work out that this time around, it’s not just the cosmetics that have been played around with.
How did it all start, though? “We’re lovers of fast cars,” Paul confesses. “So when we heard that the turbo tuning company Mosselman from Holland was developing tuning packages for the new M3/M4, we thought it would be rude not to work alongside them!” You can probably see where this is going…
Because the new M4 sports two boost snails under its muscular hood, the tuning potential has got engine boffins feeling a lot more fizzy with excitement in the trouser department than that of the previous, normally aspirated model. Working with Mosselman, the daunting task of delving into the car’s complex innards began with replacing the regular turbos for the Dutch firm’s own hybrid affairs, giving far more power and even less lag.
A bit of custom tweaking and mapping in Mstyle’s garages soon saw some seriously impressive results, with the car seemingly taking it all in its stride. “It’s insanely fast, but also surprisingly smooth,” Paul reveals. Adding to the drama is a complete turbo-back exhaust system from Mosselman, using very little in the way of silencing to produce a soundtrack that has to be heard to be believed. Needless to say, then, this car is best enjoyed with the roof firmly down!
With 425bhp as standard, the new M4 is no couch potato. But adding another 200 ponies into the pen makes all the difference, with the car smashing through the trick seven-speed ‘box before you’ve really got time to figure out why your head has suddenly been flung backwards. “We get some funny reactions from other motorists…” Paul laughs. And we’re not at all surprised!
But of course, this is Mstyle we’re talking about; the backbone of the UK’s BMW tuning scene. This car was never going to remain looking standard forever. Rifling through the firm’s extensive parts bin and phone book, Paul decided to hit up BC Forged to supply something a little different in the wheel department. “They M4 comes with a pretty extreme offset and wheel size to start with,” he tells us. “So we had to work long and hard with the guys at BC to get these bigger wheels sitting just right.”
What we’re looking at as a result is a quartet of staggered 20-inchers, boasting a bonkers 12” of girth on the rear, and being protected from the road by insane 25-profile Hankook rubber. Thanks to the custom offsets, the ten-spokers sit fantastically under the car’s hot rod-esque wide arches, just adding to the overall menace of the thing.
With a ride height this low, on a car this valuable, you’re probably expecting to find some fancy air ride suspension system in the boot, right? You’ll be shocked to hear that Paul has daringly but commendably opted for a track-focused static coilover system, then, again from the geniuses at Mosselman, and aimed to exploit every single one of those angry horses. We can only imagine what this beast would be like to nail around a racetrack…
The M4 is one of the most aggressive cars money can buy as standard, so Paul has merely heightened to this appeal looks-wise with the addition of some subtle carbon fibre Mstyle goodies to make that crisp white paint job really pop. The splitters and side skirt extensions tie everything in nicely, topped off with kidney grille replacements in the same magical lightweight metal. To fully rep the Mosselman power upgrades, a decal set has been carefully applied, with the fabled power figure subtly displayed. At least those who try to take this thing on will at least get a bit of warning… Inside, it merely takes some Mstyle carbon fibre steering wheel panels and a similar gear knob to hit what must nearly be perfection for a fast, luxury cabin. An extremely comfortable place to nail some incredible 0-60 times!
You probably don’t need us to tell you that cars have come a long, long way in recent years, and it’s great to see that Mstyle are riding this wave in the coolest, fastest way possible. This M4 is a great way for the team to show off what they can do to for other BMW enthusiasts – by creating a monster that really does do it all.
