BMW M4 CS Breaks Free From the Track in New Forza Horizon 6 Showcase

A Nürburgring lap time is impressive, but Forza Horizon has never been particularly interested in keeping performance cars where they are supposed to be. The latest Forza Horizon 6 showcase puts the 2025 BMW M4 CS at the centre of that philosophy, taking BMW’s sharpened four-seat coupé away from the circuit and onto the roads of Horizon Japan.

“The track is not enough for the BMW M4 CS” is the entire premise, and it is an unusually appropriate one. The real M4 CS was developed as the bridge between the everyday usability of the M4 Competition and the considerably more uncompromising M4 CSL. In Forza Horizon 6, that same balance becomes an excuse to do exactly what Horizon does best: take a car engineered around lap times and give it an entire open world instead.

The BMW M4 CS is one of Horizon Meets’ major new cars

The showcase arrives as part of Horizon Meets, the sixth Festival Playlist Series for Forza Horizon 6. The October update is centred around car-meet culture, with a limited-time 7-Eleven collaboration, a themed Konbini Car Meet, additional Horizon Play content and a fresh selection of reward vehicles.

The M4 CS is one of only three cars in the Series that Playground Games specifically identifies as new to Horizon, alongside the 2000 Honda Prelude Type SH and 1968 Holden Monaro GTS 327. That gives the BMW a little more significance than another returning vehicle being rotated back into the Festival Playlist. This is its Horizon debut.

It is also positioned as one of the Series’ main long-term rewards. Players need 80 Festival Playlist points during Horizon Meets to unlock the 2025 BMW M4 CS, with the Series running from October 8 until November 5. Above it sits the returning 2015 Koenigsegg One:1 at 160 points.

That makes the timing of the new showcase useful. Rather than introducing a completely unknown car, Forza is giving one of the current Series’ headline rewards its own moment after Horizon Meets has already begun.

Forza has retained the numbers that make the CS considerably more than another M4

In Forza Horizon 6, the M4 CS arrives with 543 horsepower, 479 lb-ft of torque, all-wheel drive and an S1 733 stock performance rating. Playground Games lists a 2.99-litre engine, accurately reflecting the 2,993 cc version of BMW’s S58 twin-turbocharged straight-six.

The 543 hp figure is particularly important because the CS is not simply an appearance package for the regular G82 M4.

BMW increased output by 20 hp over the contemporary M4 Competition Coupé with M xDrive, principally through revised engine management and higher turbocharger boost pressure. Peak torque remains 479 lb-ft and is available across a broad 2,750–5,950 rpm range, while the engine continues pulling to a 7,200 rpm redline.

The result is a car BMW quotes at 3.4 seconds from 0–100 km/h, 11.1 seconds from 0–200 km/h and an electronically limited 188 mph — approximately 302 km/h — top speed with the standard M Driver’s Package.

Those specifications help explain why simply placing the car on a conventional racing circuit would almost undersell what Horizon can do with it.

The CS was deliberately created to live between the M4 Competition and M4 CSL

BMW’s modern CS formula occupies a very specific part of the M hierarchy.

The regular M4 Competition is already enormously capable, while the M4 CSL pushes much further toward a specialised track-car philosophy. The M4 CS sits between the two: more power, less weight and more aggressive chassis tuning than the Competition, but without abandoning the rear seats and road-going versatility that make an M4 usable outside a circuit.

BMW attacked weight throughout the car. Carbon-fibre-reinforced plastic is used for the roof, bonnet, front splitter, front air intakes, mirror caps, rear diffuser and rear spoiler, while more carbon appears inside through the centre console, shift paddles, trim and structural elements of the bucket seats.

The titanium rear silencer alone saves more than eight pounds compared with the conventional exhaust system. Altogether, BMW says the lightweight measures remove 77 pounds compared with the M4 Competition Coupé with M xDrive.

It is still recognisably an M4, but almost every part of the package has been pushed toward a more focused purpose.

That is what makes the premise of the Forza showcase work. Taking a pure racing prototype away from a track would hardly be surprising in Horizon. Taking something deliberately engineered to retain both track performance and road usability makes the transition much more natural.

Its Nürburgring time gives “the track is not enough” considerably more weight

There is also no question that the M4 CS can handle a circuit.

BMW recorded an official, notarised 7:21.989 lap of the full 20.8-kilometre Nürburgring Nordschleife with the G82 M4 CS. Within BMW M’s modern hierarchy, that puts it behind the more extreme M4 CSL but firmly establishes that the CS badge represents genuine performance engineering rather than marketing language.

The car’s S58 engine has particularly direct motorsport connections. BMW notes that the 3.0-litre straight-six provides the basis for the powerplant used in the M4 GT3, while cooling, oil supply and internal construction were developed to cope with sustained high engine speeds and lateral loads associated with circuit use.

Even its road-going chassis setup is unusually specific. The M4 CS receives unique wheel-camber settings, dampers, auxiliary springs and anti-roll bars, along with model-specific calibration for its Adaptive M suspension, steering, braking system, DSC and M Dynamic Mode.

So when Forza removes the M4 CS from a racetrack, it is not because the car lacks circuit credentials. It is doing almost the opposite: taking something that has already demonstrated those credentials and asking what happens when the barriers disappear.

M xDrive gives the M4 CS another side that fits Horizon particularly well

The M4 CS is also not locked into the behaviour people might traditionally associate with a powerful rear-wheel-drive BMW coupé.

Its M xDrive all-wheel-drive system is rear-biased, using an electronically controlled multi-plate clutch to distribute torque between the axles. BMW also integrates it with the Active M Differential at the rear, attempting to combine the traction advantages of AWD with the responses expected from an M car.

The real car can go considerably further. Drivers can select a more rear-focused 4WD Sport setting, while disabling DSC makes a pure 2WD mode available.

Forza’s published stock specification simply categorises the vehicle as AWD, and the promotional material does not establish how every real-world drive-mode function has been reproduced in-game. But the underlying engineering explains why the car makes sense across Horizon Japan’s very different environments.

A vehicle capable of putting 543 hp through four driven wheels is useful when a road stops being perfectly smooth, when elevation changes become more aggressive or when a high-speed route is considerably less predictable than a closed circuit.

The M4 CS was built to find grip under difficult conditions. Horizon provides plenty of opportunities to make that relevant.

The visual aggression is part of the CS identity too

The performance changes are accompanied by a design that makes very little attempt to hide what this version of the M4 is.

BMW gave the CS a largely frameless kidney grille with red detailing, model-specific badges, extensive exposed carbon fibre and the particularly distinctive yellow headlight signature inspired by GT racing cars. At the rear, its laser-light technology produces the three-dimensional lighting effect previously used by the M4 CSL.

Its launch specification also included unusually expressive paint choices. Frozen Isle of Man Green metallic became one of the model’s defining colours, accompanied by Riviera Blue, Brooklyn Grey metallic and Black Sapphire metallic.

That makes the M4 CS particularly well suited to an update called Horizon Meets.

The Series is not solely about competition. It is explicitly built around the social side of car culture — gathering, displaying builds and meeting other players — and the M4 CS already looks like the sort of vehicle that announces itself before the engine starts.

Playground Games even acknowledges that in its own description of the car, asking whether the exterior could possibly become more dramatic before conceding that Horizon players will inevitably try.

It also arrives during a Series built around driving together rather than simply racing

Horizon Meets is an unusually appropriate home for this particular BMW because Series 6 is as interested in what players do between races as it is in the races themselves.

The update introduces a limited-time 7-Eleven-themed Car Meet, new EventLab props, 200 additional Horizon Play levels and extra vehicles for Spec Racing. Playground Games describes the Series around the places where players gather before forming a Convoy, making automotive culture itself the theme rather than a particular discipline of motorsport.

That changes the context around the M4 CS.

In a dedicated circuit racer, most of the conversation would naturally revolve around whether the car’s Nürburgring credentials translate into competitive lap times. Horizon can use that side of it, but it can also let players cruise through Japan, photograph it, modify it, bring it to a meet or send it down roads BMW’s engineers never had in mind.

The new showcase leans into that broader fantasy rather than treating the M4 CS as another statistic in an S1-class garage.

The M4 CS represents exactly the kind of car Horizon was built to exaggerate

There is a useful contradiction at the centre of the BMW M4 CS.

BMW spent considerable engineering effort making the car faster around a circuit. Carbon fibre reduces mass. Chassis geometry becomes more aggressive. The engine produces more power. The cooling and lubrication systems are designed to survive sustained performance driving. Even the headlights borrow visual language from GT racing.

And then BMW retained enough practicality that the car could still leave the circuit and function as an actual road-going M4.

Forza Horizon 6 removes the practical limitations from that equation.

There is no commute to consider, no tyre bill waiting at the end of a mountain road and no reason a Nürburgring-developed BMW has to spend its life chasing tenths of a second between kerbs. Horizon Japan gives it motorways, mountain passes, urban streets and the freedom to turn a carefully engineered road-and-track compromise into something much less sensible.

That is ultimately why “the track is not enough” works better for the M4 CS than it would for many of the cars in Forza Horizon 6.

The real machine was designed specifically so that the track would not have to be enough.

The BMW M4 CS is part of Horizon Meets until November 5

The 2025 BMW M4 CS is a Series reward in Forza Horizon 6’s Horizon Meets Festival Playlist, requiring 80 points. Horizon Meets began on October 8 and runs until November 5, giving players the full Series to work toward the new-to-Horizon BMW.

In stock form, Forza rates it at S1 733, with 543 hp, 479 lb-ft of torque and AWD. Those figures closely mirror the real vehicle rather than exaggerating its performance simply to make it fit Horizon’s upper classes.

The latest showcase does not announce another variant, upgrade pack or separate BMW event. Its purpose is simpler: give one of Series 6’s major new cars a dedicated spotlight and demonstrate why a machine created around circuit performance belongs just as naturally on Horizon Japan’s open roads.

The Nürburgring proved what the M4 CS can do when the route is fixed. Forza Horizon 6 is interested in what happens when it is not.
