BMW M4 F82 and M3 F80: history, specifications and buying guide

The BMW M4 F82 is the first car to carry the M4 badge: the coupe version of the fifth-generation M3, built at BMW's Munich plant from 2014 to 2020. Its sisters are the F80 M3 saloon, built at Regensburg, and the F83 M4 Convertible. All three use the S55, a 3.0-litre twin-turbo straight six of 431 hp in standard form and up to 500 hp in the water-injected M4 GTS, and about 112,060 of the F8x cars were made. In October 2026, 127 of them advertised on PistonHeads were priced from £16,795 to £90,995, with half at £30,000 or less.

History of the BMW M4 F82 and F80 M3

BMW M GmbH developed the F80 M3 and F82 M4 together and launched them together, the first time the coupe and four-door had arrived at the same moment. BMW's December 2013 press kit explains the new name: the "M4" badge refers to the 4 Series coupe the car is based on, and "for the first time, the Coupe will be introduced at the same time as the four-door variant", the M3 saloon. More than 40,000 of the fourth-generation (E92) M3 Coupe had been built, BMW said.

The September 2013 technical reveal

BMW released the first technical details at its "Technology Days" media event; its press release went out just before midnight on 24 September 2013, promising "approximately 430 hp", torque "far beyond 500 Newton metres" and a weight "just under 1,500 kilograms". SkiddMark reported it on 25 September 2013, giving the engine as 424bhp at 7,500rpm and 369lb ft (500Nm), and quoting Albert Biermann, head of development at BMW M, who called the extra torque "central to the new car's performance gains".

SkiddMark's report set the weights out generation by generation: about 1,580kg unladen for the outgoing E92 M3 Coupe, 1,495kg for the E46 M3 before it, and a target of matching the E46. Its list of savings: a manual gearbox 12kg lighter, 5kg from aluminium control arms, wheel carriers and axle subframes, 3kg from the forged aluminium five-link rear axle, a one-piece carbon-fibre propshaft 40 per cent lighter than the old two-piece shaft, a carbon roof on the M3 saloon for the first time, and a boot lid of carbon fibre and plastic on the M4, as on the 1,385kg E46 M3 CSL. The S55 engine weighed about 195kg, SkiddMark wrote, some 10kg less than the 4.0-litre S65 V8 it replaced.

The same report predicted a Competition Package of "around 444bhp", 0–62mph in under 4.5 seconds, the standing kilometre in 21 to 22 seconds, 33.1mpg and CO2 below 200g/km (which, SkiddMark noted, would put the M4 ahead of Porsche's lighter 911 Carrera S on economy), a debut at the Detroit motor show in January 2014, and an M3 saloon at about £55,000. Biermann said that, bore and stroke apart, the S55 and the 1 Series M Coupe's six were "worlds apart, both in their construction and induction methods". DTM drivers Bruno Spengler, the 2012 champion, and Timo Glock had helped set the cars up on the Nordschleife.

Final figures, Detroit and the UK launch

The final figures came in December 2013: 431 hp from 5,500 to 7,300rpm and 550Nm (406lb ft) from 1,850 to 5,500rpm, about 40 per cent more torque than the E92 M3, with fuel consumption and emissions about 25 per cent lower. The M4 Coupe weighed 1,497kg to the DIN standard, about 80kg less than an equivalent E92. BMW of North America's release of 11 December 2013 quoted 425 hp (its own rating of the same engine), a Detroit debut in January 2014 and US prices of $62,925 for the M3 and $65,125 for the M4.

In Britain both cars went on sale on 21 June 2014, at £56,190 for the M3 Saloon and £56,650 for the M4 Coupe, according to BMW UK's media launch presentation of June 2014. That was £2,905 and £1,670 more than the outgoing cars, with 19-inch wheels, adaptive M suspension, heated seats and front and rear parking sensors added as standard. The M4 Convertible followed on 6 September 2014 at £60,745.

Competition Package and the facelift

From spring 2016 BMW offered a Competition Package on all three body styles (see below). Autocar dates the mid-life facelift, BMW's Life Cycle Impulse (LCI), to 2017 for the M4: LED headlights and tail lights, a new front apron, new trim and upholstery choices and upgraded navigation. PistonHeads notes that the M3 saloon received its LED tail lights in 2016, a year before the M4.

Why the M3 saloon stopped first

The F80 M3 went out of production in May 2018. Tony Middlehurst's PistonHeads buying guide of April 2020 gives the reason as the cost of fitting the petrol particulate filter needed for the WLTP emissions test. The M4 Coupe and Convertible were re-homologated with the filter and stayed in production. The last special edition, the M4 Edition ///M Heritage, was built between November 2019 and April 2020, and a UK recall (below) covers M4 Coupes built as late as 5 June 2020. Its successor, the G82 M4 Coupe, uses the S58 straight six; by mid-September 2026 BMW had built 53,293 of them, according to the BMWBlog count below.

BMW M4 F82 design and engineering

The F82 M4 is a 4 Series coupe rebuilt by BMW M with its own engine, cooling, suspension, steering and lighter body panels. BMW built the M4 in Munich, on the same line as the standard 4 Series Coupe and next door to the BMW Motorsport headquarters where the original E30 M3 was conceived, and the M3 saloon in Regensburg alongside the 3 Series, according to page 20 of BMW's December 2013 media information.

The S55 twin-turbo straight six

The S55B30 is a 2,979cc straight six with a bore of 84.0mm, a stroke of 89.6mm and a compression ratio of 10.2:1. It has two mono-scroll turbochargers, direct injection, Valvetronic and Double-VANOS, a closed-deck crankcase with arc-sprayed cylinder bores in place of liners, a forged crankshaft and a magnesium sump. It revs to 7,600rpm, which BMW called unusually high for a turbocharged engine. BMW fitted an indirect intercooler, a side-mounted water cooler and an electric pump that keeps cooling the turbocharger bearings after the engine stops. Electrically controlled flaps in the exhaust change its sound with the driving mode, and BMW UK's launch presentation listed the weight saved part by part: 1.8kg from the crankshaft, 2.2kg from the crankcase, 1kg from the magnesium sump.

Transmission: manual or DCT?

The standard gearbox was a six-speed manual with a twin-plate clutch, carbon synchroniser linings and automatic throttle blips on downshifts, a feature that had previously been available only with the twin-clutch box. The option, at £2,645 in the UK, was the third-generation seven-speed M Double Clutch Transmission (M DCT) with launch control. BMW UK said the DCT was 0.2 seconds quicker to 62mph than the manual, 1.9mpg more economical and 10g/km cleaner. The CS, GTS and DTM Champion Edition came only with the DCT; the standard F82 and F83 offered both transmissions.

Most buyers took it: of the 34,677 F80 M3 saloons counted by a BimmerPost member and reported by CAR magazine in South Africa, 29,251 had the DCT and 5,426 the manual. Autocar calls the DCT the "better wingman" for the engine and the manual "the more interactive experience".

Carbon fibre and aluminium

Both body styles have a carbon-fibre roof, which saves 5kg on the M3 and more than 6kg on the M4 and lowers the centre of gravity; a steel roof came with the optional sunroof. The bonnet, with its power dome, and the front wings are aluminium. The M4's boot lid, with its built-in spoiler, is carbon fibre and plastic, and the strut brace across the engine bay is a 1.5kg carbon-fibre part. Front and rear axles use aluminium arms and wheel carriers, and the rear subframe is bolted rigidly to the body with no rubber mounts.

Chassis, steering and brakes

The steering is electrically assisted, with Comfort, Sport and Sport+ settings, and the optional adaptive dampers have the same three modes. An electronically controlled multi-plate differential, the Active M Differential, varies its lock between 0 and 100 per cent. M compound brakes with blue callipers were standard; carbon-ceramic brakes with gold callipers cost £6,250 in the UK. Standard wheels were forged 18-inch alloys with 255/40 front and 275/40 rear tyres, with 19-inch wheels optional (standard in the UK).

Interior and equipment

Inside, the F82 M4 has the 4 Series dashboard with M dials, an M leather steering wheel with colour stitching, and front sports seats with a one-piece back modelled on racing buckets and, for the first time, an illuminated M logo in the backrest. The rear seat backs fold 60:40. UK cars came with Merino leather, heated electric front seats, an 8.8-inch screen with BMW Professional Media and adaptive M suspension as standard; adaptive LED headlights (£1,600) and an M head-up display (£825) were options, according to BMW UK.

BMW M4 F82 specs and performance

A standard F82 M4 Coupe has 431 hp and 550Nm, reaches 62mph in 4.1 seconds with the DCT and is limited to 155mph, or 174mph with the optional M Driver's Package. The figures below are BMW's, from the press material for each car; weights are BMW's DIN figure unless marked EU, which includes 75kg for the driver and luggage except where the figure is "excl. driver".

Production figures in the last column are from MDataWorks via BMWBlog, 5 October 2026 (M4 Coupe) and BimmerPost data via CAR magazine (M3, Competition and the 1,263 M3 CSs); those counts are not BMW's. The GTS, DTM Champion Edition and "about 1,200 planned" M3 CS figures are BMW's own limits, and MDataWorks' 57,514 coupes include the GTS, DTM and CS cars.

How fast is the BMW M4 F82? Acceleration and top speed

The standard M4 Coupe covers 0–62mph in 4.1 seconds with the DCT and 4.3 seconds with the manual, and the standing kilometre in 21.9 and 22.2 seconds; 50–75mph in fourth takes 3.5 seconds. Top speed is limited to 250km/h (155mph), or 280km/h (174mph) with the M Driver's Package. The quickest F8x cars, the GTS and DTM Champion Edition, reach 62mph in 3.8 seconds and are limited to 305km/h (189mph). BMW quoted Nordschleife lap times of 7min 28sec for the GTS and 7min 38sec for the CS, which it placed between the M4 and the GTS.

Dimensions, weight and economy

The M4 Coupe is 4,671mm long, 1,870mm wide and 1,383mm high on a 2,812mm wheelbase; the M3 Saloon has the same length and wheelbase but is 1,877mm wide and 1,424mm high. The coupe's boot holds 445 litres and the saloon's 480; the convertible's holds 370 litres with the roof up and 220 with it folded. The fuel tank holds about 60 litres. Official combined economy for the coupe and saloon was 32.1mpg (204g/km CO2) with the manual and 34.0mpg (194g/km) with the DCT; the convertible's was 31.0 to 32.5mpg. The convertible's three-section metal roof opens in about 20 seconds, at up to 11mph.

F82 M4 versions: body styles, Competition and special editions

The F8x range has three body styles (F80 saloon, F82 coupe, F83 convertible), one performance upgrade, the Competition Package, and seven limited or special models.

What is the difference between the F80, F82 and F83?

F80 is BMW's code for the four-door M3 Saloon, F82 for the M4 Coupe and F83 for the M4 Convertible; enthusiasts call the three "F8x". They share the engine, gearboxes and suspension. Top Gear's Ollie Marriage, at the launch in Portugal in 2014, found that the suspension settings differ "fractionally" to allow for the saloon's extra 23kg, and that the two have the same track widths, which makes the M3 80mm wider than a standard 3 Series. The F83 weighs about 250kg more than the F82 with the manual gearbox and is 0.3 seconds slower to 62mph.

M4 Convertible (F83)

BMW's media information for the M4 Convertible, dated April 2014, describes a three-section folding metal hard top, fully lined, and a DIN weight of 1,750kg, about 60kg less than the E93 M3 Convertible it replaced.

Competition Package

Announced in January 2016 for all three body styles, the package added 19 hp, for 450 hp, and 0.1 seconds off every 0–62mph time. It retuned the adaptive dampers with new springs and anti-roll bars, reprogrammed the differential and stability control, and added forged 20-inch "666M" wheels (265/30 front, 285/30 rear), lightweight sports seats in the coupe and saloon, seat belts with M stripes, an M sports exhaust with black chrome tailpipes and gloss-black Shadow Line trim. SkiddMark's 2013 guess of "around 444bhp" was right: 450 PS is 444bhp. Autocar puts a Competition car at about £5,000 more than a comparable standard one today and would choose the Competition.

M4 GTS

The GTS made its world debut at the Tokyo motor show, which ran from 30 October to 8 November 2015, and was built in 2016 as a limited production run of 700 to mark 30 years of the M3. According to BMW's M4 GTS press kit, water injection raised the output to 500 hp and 600Nm with fuel consumption no higher than the standard M4's. It had carbon-fibre bucket seats with no rear seats, an adjustable carbon rear wing, a carbon front splitter, Acid Orange wheels and the first OLED tail lights on a production car. A Clubsport Package added an orange roll-over bar behind the seats and six-point harnesses. BMW said it was the first of the M3 and M4 high-performance special editions to be sold in North America. Autocar says only 30 right-hand-drive GTSs were made.

M4 DTM Champion Edition

After Marco Wittmann's second DTM title in October 2016, BMW built 200 M4 DTM Champion Editions, all in Alpine White with BMW M stripes, using the GTS's 500 hp water-injected engine, for €148,500 in Germany.

M3 30 Jahre and M4 Convertible 30 Jahre

The M3 "30 Jahre M3" of summer 2016 was a run of 500 saloons in Macao Blue with the Competition Package's 450 hp, with numbered "1/500" carbon interior trim, according to BMW Mexico's release of November 2016; PistonHeads says 30 came to the UK. PistonHeads also records an M4 Convertible version in 2018.

M4 CS

The CS was built to sit between the Competition and the GTS. BMW's CS press kit, dated April 2017, lists 460 hp, 600Nm, a carbon-fibre bonnet about 25 per cent lighter than the standard aluminium one, a carbon front splitter, boot-lid lip and diffuser, the OLED tail lights, and two colours of its own, San Marino Blue and Lime Rock Grey. With it BMW introduced its naming order: standard, then Competition, then CS.

M3 CS

The saloon version was announced on 7 November 2017 with the M4 CS's 460 hp and 600Nm, a carbon bonnet and roof, and production of about 1,200 from March 2018, about 550 of them for the US. CAR magazine's figures put the final total at 1,263.

M4 Edition ///M Heritage

The last F82 special was a run of 750 coupes with the 450 hp engine, in Laguna Seca Blue, Velvet Blue or Imola Red, with a roof strip in the BMW M colours and Orbit Grey wheels, shown at the Nürburgring DTM round in September 2019 and built from November 2019 to April 2020, according to BMW's release.

The BMW M4 on the track: DTM and GT4

The M4 name raced in the DTM from its first season: the BMW M4 DTM racing car won the 2014 drivers' title for Marco Wittmann of BMW Team RMG. According to BMW's report from the Lausitzring on 14 September 2014, sixth place there settled it with two rounds left. Wittmann, 24, had won the opening race at Hockenheim and three more; he led Mercedes driver Christian Vietoris by 69 points, BMW Team RMG led the teams' table and BMW the manufacturers'.

Wittmann won again in 2016 in the Red Bull BMW M4 DTM, finishing fourth in the final race at Hockenheim on 16 October to beat Audi's Edoardo Mortara by four points, 206 to 202. BMW's report calls him the first BMW driver to win the DTM title twice.

For customer teams BMW built the M4 GT4. Its first race was a test run with Schubert Motorsport at the Dubai 24 Hours in January 2017, while the car was still in development, driven by Jörg Müller, Jens Klingmann and Ricky Collard; it covered just under 3,000 kilometres in race conditions, according to BMW Motorsport News 02/17.

How many BMW M4 F82s were made?

About 57,514 F82 M4 Coupes were built, out of 112,060 F8x cars of all three body styles, according to production counts by MDataWorks published by BMWBlog in October 2026. BMW has not published its own figures. The F80 M3 accounts for 34,677 by the BimmerPost count reported by CAR magazine, of which 16,057 went to the US, 1,104 to Canada and 8,745 to right-hand-drive markets such as Britain and South Africa; if the two counts agree, that leaves about 19,900 F83 Convertibles. The most common M3 colour was Black Sapphire (6,111), and nine were built in Pyrite Brown. Five special models had published limits: 700 GTSs, 200 DTM Champion Editions, 500 M3 30 Jahre, about 1,200 M3 CSs and 750 Heritage Editions.

How much is a BMW M4 F82 worth?

Most F82 M4s on the UK used market are priced between £20,000 and £40,000. On 27 October 2026 SkiddMark collected 127 priced F8x adverts from PistonHeads' F82 M4 and F80 M3 pages (every year and colour filter), and the table summarises them. They are asking prices, and some include tuned cars; one 2018 Competition advert lists a stage 2 remap to 587PS.

The cheapest car was £16,795, and the dearest whose advert names no edition was a 2015 M4 at £70,000 with 13,909 miles. The one DTM Champion Edition was £74,995 with 20,400 miles, and the two GTSs had fewer than 1,000 miles each. A new M4 Coupe cost £56,650 in 2014, so a typical 2014–2016 car now asks less than half its list price.

Ownership: reliability and known faults

The F8x has a good mechanical record apart from one serious, rare fault on early cars, the crank hub. PistonHeads said in 2020 that it had "an excellent record so far", and Autocar calls the M4 "well made and robust" with "a number of common faults".

What is the crank hub problem?

On the S55, as on BMW's N54 and N55 engines, the hub that drives the timing gear is held to the crankshaft by a single bolt with no key. PistonHeads explains that hard up- or downshifts can make the hub slip, upsetting the valve timing. It puts the rate at about one engine in 200 and says it affected early cars built before December 2015; a new part introduced by BMW is "said to have fixed the problem on 2016-on cars". Autocar's used review of March 2025 lists the symptoms as a rough idle and loss of power, and at worst engine failure, and advises a buyer to check whether the hub has been replaced and to consider fitting a crank bolt capture plate as a precaution.

Is the F82 M4 reliable? Other issues to check when buying

Autocar's list: perished gaskets on the rocker cover, oil filter housing and sump (look for drips); a tapping noise on a cold start that can mean a misaligned exhaust camshaft, an £800 to £1,000 repair; brake discs and pads at more than £1,000 a set; a corroded air-conditioning condenser; and, on the convertible, blocked roof drain tubes that let water into the cabin. PistonHeads adds cracks in M Performance exhausts on 2018 and older cars where the tailpipes leave the silencer, cracked M seat badges on 2015–2017 cars, stone chips on the wide rear arches and sills, squeaks and rattles, boot lids that will not open fully or shut without a slam, and noisy brakes; it says the adaptive dampers were "worth having".

PistonHeads also notes that the one-piece carbon propshaft was dropped on cars built from November 2017 (the CS and GTS kept it) because it did not leave room for the particulate filter.

Recalls in the UK

DVSA's recall file lists these for the F8x cars, among others:

• R/2019/012: the flange of the carbon propshaft may detach, on 973 M3s and M4s built between 9 March and 30 September 2016; the shaft is replaced with a different design.
• R/2015/240: the propshaft slide joint may not have been lubricated, six cars built May to September 2015.
• R/2023/016: driver's airbag inflator may rupture, 5,046 M4 Coupes, 2,083 Convertibles and 2,486 M3s built up to 29 June 2017.
• R/2017/011: airbag igniters, 668 M4s built 8 August to 14 November 2016.
• R/2020/352: missing injector damping elements could cause fuel leaks, 24 M4s built 4 March to 5 June 2020.

Maintenance, running costs and road tax

Oliver Cooper, an owner quoted by Autocar who has covered 50,000 miles in a 2018 M4 Competition, allows £1,000 to £1,500 a year for servicing and tyres and pays £1,500 a year for BMW's extended warranty. In the UK an M4 first registered before 1 April 2017 is taxed on its CO2: 194g/km (DCT) falls in band J at £410 a year and 204g/km (manual) in band K at £445, according to GOV.UK's rate tables read on 27 October 2026. A car registered from April 2017 pays the standard £200 a year, plus £440 for five years from its second tax payment because every M4 cost more than £40,000 new.

BMW M4 F82 rivals

At launch, BMW UK named the Mercedes C63 AMG Coupe and the Audi RS5 Coupe as the M4's rivals, both with naturally aspirated V8s. Its own comparison, dated May 2014, is reproduced below; figures in brackets are for automatic gearboxes.

Reception

Ben Barry, driving a DCT M4 at the launch for CAR magazine, wrote that it sounded "much like a big capacity turbodiesel at part throttle" and gave it four stars out of five: "a great car, but it feels more competent than its predecessor rather than any more enjoyable to drive". He rated the optional carbon-ceramic brakes "as good as anything I've ever tried in a supercar".

Ollie Marriage of Top Gear, in issue 257 (2014), called the M3 "a tremendous road car: fast, poised, effortless" and the M4 "wonderfully predictable" at Portimão, but found "no reason to use high revs" with peak torque available from 1,850rpm, and noted that the engine note was "artificially amplified by the ECU and pumped in through the speakers". He called the Sport Plus mode's anti-lag, which keeps the turbos above 120,000rpm off the throttle, the M3's "party trick". Autocar's road test said that in its angriest settings the M4 was "adeptly tied down yet compliant over the worst bumps", and its 2025 used review rates the car 8 out of 10.

Questions

What engine is in the F82 M4?

The S55B30, a 2,979cc straight six with two mono-scroll turbochargers, built by BMW M for the F80 M3 and F82/F83 M4. It gives 431 hp and 550Nm as standard, 450 hp with the Competition Package, 460 hp in the CS and 500 hp with water injection in the GTS.

Why is the coupe called the M4 and not the M3?

BMW moved its two-door 3 Series to a new 4 Series name in 2013, and the M version took the M4 name to match. The four-door saloon stayed the M3, and for the first time the two were launched together.

Where was the F82 M4 built?

At BMW Plant Munich, on the same line as the 4 Series Coupe. The F80 M3 saloon was built at Regensburg with the 3 Series.

How much did the F82 M4 cost new?

£56,650 for the M4 Coupe with the manual gearbox when UK sales began on 21 June 2014, £59,145 with the DCT, and £60,745 for the M4 Convertible. The M3 Saloon was £56,190.

Does every F82 M4 have a carbon roof?

Every M4 Coupe and M3 Saloon has a carbon-fibre roof unless it was ordered with a sunroof, which came with a steel roof. The convertible has a folding metal roof.

Is the Competition Package worth having on an F82 M4?

It adds 19 hp, firmer and retuned suspension, a retuned differential, 20-inch wheels, lighter seats and a sports exhaust. Autocar recommends it, and in October 2026 PistonHeads adverts naming Competition had a median asking price of £31,495, against £25,995 for those naming neither Competition nor an edition.

Which F82 M4 years are best to buy?

PistonHeads links the crank hub fault to cars built before December 2015 and says a new BMW part "is said to have fixed the problem on 2016-on cars", which could also have the Competition Package. Cars built from November 2017 have a conventional propshaft in place of the one-piece carbon one, to leave room for a particulate filter.
