The new BMW M3 and M4 have been revealed in standard 480hp guise and 520hp Competition form. Read on for full details on these all-new sports cars

  • 480hp as standard
  • 510hp in Competition trim
  • Manual/automatic gearbox
  • 2WD/4WD options
  • 0-60 in 3.9 seconds
  • 180mph top speed
  • Revamped interior
  • Numerous upgrade packs
  • Priced from £75,000

The new BMW M3 and M4 pairing will go head-to-head with the likes of the Mercedes-AMG C63 and Audi Rs5 when they hit the roads later this year. As well as a complete cosmetic overhaul, these 3.0-litre straight-six sports cars will be available with four-wheel drive for the first time.

2021 BMW M3 and M4 design

The new BMW M3 and M4 both feature a similar huge grille to the upcoming 4 Series Coupe. Though, the gaping black-painted kidneys look far more at home on these aggressive M cars than on the humdrum 4 Series thanks to plenty of other huge (and completely real) air intakes and vents.

No fake intakes here…

The M3 and M4 get a heavily sculpted bonnet with scalloped details behind the BMW badge. Both cars are wider than their predecessors – the M4 by almost two centimetres and the M3 by almost three centimetres.

Lowered suspension makes the M3 look lower and leaner than the 3 Series.

The new cars’ side skirts are more pronounced than before, too, and you can pick from a pair of new alloy wheel designs that measure 19 inches at the front and 20 at the rear. Speaking of the rear, both the M3 and M4 come with a black rear diffuser with a quartet of 10-centimetre exhausts pipes poking out underneath.

Besides their doors and boot lids, the M3 and M4 body panels are all new.

The only body panels carried over from the standard BMW 3 Series and 4 Series are the doors and the bootlid – everything else has been given the beefed-up M treatment.  No wonder the M3 looks like a touring car and the M4 looks like a mini M8 – especially from the back.

This grainy teaser image is our best look yet at the upcoming BMW M3 Touring.

BMW has also confirmed that’ll it’ll build an M3 Touring for the first time ever. This high-performance estate will come with the bold design as the new M3 and M4 but add a bucketload of extra boot space.

The M3 and M4 get the same cabin layout as the 3 Series and 4 Series. 

2021 BMW M3 and M4 interior

The interiors of the BMW M3 and M4 have been given the M treatment, too. There’s a chunkier M Sport steering wheel with M-coloured stitching and programmable M driving mode buttons, alongside a red starter button, an M-badged gear lever and plenty of carbon-fibre trim as standard. It’s on the steering wheel, the centre console and the gear-shift paddles.

These £3,500 carbon-fibre seats will have a strong grip on your backside – and your wallet. 

The M Sport seats come with built-in M logos (that light up) and can be specced with two-tone trim – for an extra £300. Even better are the optional carbon-fibre bucket seats. They are even more supportive, come with electric adjustment and get plenty of vents to stop you feeling sweaty on a hot summer’s (track) day. Shame they’ll set you back £3,500.

The M3 and M4 come with BMW’s latest iDrive infotainment system as standard.

You don’t have to pay extra for a fancy infotainment system, though – every M3 and M4 gets BMW’s latest iDrive tech as standard. This comes with two large screens, a head-up display system, BMW’s clever personal assistant voice command system and wireless Apple CarPlay and Android Auto.

The M3 and M4 share their engine with the X3M and X4M SUVs. 

2021 BMW M3 and M4 engine and gearbox

The standard BMW M3 and M4 come with a 3.0-litre twin-turbo straight-six engine that produces 480hp. Pick a Competition model and this gets bumped up to 510hp and 650Nm of torque. That’s 60hp and 100Nm more than the old Competition cars could manage.

UK cars will all come with an automatic gearbox. 

The M3 and M4 come with a six-speed manual gearbox as standard, but you can pay extra to get an eight-speed automatic instead. This is a torque-converter instead of the old cars’ seven-speed dual-clutch gearboxes and will get the same near-bullet-proof launch control system as the BMW M8. Competition models come with this automatic gearbox as standard – you can’t get them with a manual.

The new M3 and M4 Competition will do 0-60 in under 4 seconds. 

BMW claims the new M3 and M4 Competition will do 0-60 in 3.9 seconds – that’s 0.1 seconds faster than the outgoing models. More impressive is the fact that they’ll accelerate from 50mph to 75mph a whole second quicker than the old M3 and M4 Competition.

Rear-wheel drive comes as standard but four-wheel drive will soon be available on Competition models.

2021 BMW M3 and M4 four-wheel drive

The new BMW M3 and M4 will be available with four-wheel drive instead of rear-wheel drive for the first time. This system has been pinched from the BMW M5, so it’ll let you decide how much power you want to send to the rear wheels. Turn all the electronic safety systems off and it’ll send all the engine’s power rearward to allow for some seriously smokey drifts – on a race track, of course.

As before, the M3 and M4 get a carbon-fibre roof.

2021 BMW M3 and M4 chassis and suspension

The BMW M3 and M4 come with a carbon-fibre roof to make their chassis stiffer and lower the cars’ centre of gravity to reduce body lean in fast corners. Despite this, the M3 and M4 both weigh around 1,750kg – that’s around 160kg more than the old models.

Adaptive suspension – that gives you the choice of soft setups or firmer, more sporty ones – comes as standard and you get beefier brakes than the standard 3 and 4 Series. There are six-piston callipers with 380mm discs at the front and floating callipers with 370mm discs at the back.

Optional carbon-ceramic brakes help reduce brake fade on a track. 

Carbon-ceramic brake discs measuring 400mm at the front and 380mm at the rear are available as part of an £8,000 upgrade pack that also bumps the top speed from 155mph to 180mph.

Carbon fibre sills and a new front splitter are part of the M Performance Parts upgrade.  

BMW M3 and M4 Performance parts

You can upgrade the look of the BMW M3 and M4 further with a carbon pack as part of the optional M Performance Parts.  This includes a redesigned front bumper with deep carbon-clad intakes instead of plastic mesh, carbon door mirrors, a carbon rear spoiler and a carbon finish for the rear diffuser. All in, it costs £4,000.

A titanium exhausts system and larger alloy wheels are available. 

Other optional M Performance parts include a titanium exhaust that’s five kilograms lighter than the standard steel item. It looks different, too, thanks to a new stacked arrangement of the four exhaust tips.

You can also add adjustable coilover suspension to your M3 and M4 that lets you lower the car by 10mm. New alloy wheels are also available that measure 20 inches in the front and 21 in the rear.

Interior upgrades include carbon fibre and Alcantara trim.

You can also choose from a selection of M Performance interior upgrades. These add additional carbon fibre to the door sills and Alcantara – instead of leather – trim on the steering wheel.

The new BMW M3 and M4 are on sale now. UK deliveries are expected in Spring 2021.

2021 BMW M3 and M4 price and release date

The BMW M3 and M4 are on sale now, but in the UK, you can only get the upgraded Competition models. That means there’ll be no 480hp versions and you won’t be able to get a six-speed manual gearbox. The M3 Competition costs from £75,000 and the M4 Competition will hit you with a £76,200 bill. That’s getting on for £8,000 more than the outgoing cars. The first UK deliveries are expected in March 2021.
