The letters BMW CSL, CS, GTS and Competition mark the most special versions of BMW M cars. They usually mean more power, less weight, a sharper chassis and, often, a limited production run. For collectors, these badges can double the value of a car.
In this guide we explain what each badge means, the history behind them, from the 1970s 3.0 CSL to the modern M4 CSL, and how these cars differ from the standard models.
BMW CSL: the lightweight legend
CSL stands for "Coupé Sport Leichtbau", which means coupé sport lightweight. It is the most famous of these badges, and BMW uses it only for very special cars.
The original was the BMW 3.0 CSL of the early 1970s, a lightweight version of the E9 coupé. It used thinner steel, aluminium panels and plastic windows to reduce weight, and it was built so that BMW could race it. With its large rear wing, the racing version became known as the "Batmobile" and won many touring car titles.
The name returned in 2003 with the E46 M3 CSL. It weighed about 110 kg less than the normal M3, had a carbon roof, a carbon air intake, 360 hp and a sharper chassis. About 1,400 were built, and it is now one of the most valuable modern BMWs.
In 2022 BMW revived the name again with the M4 CSL, limited to 1,000 cars, with 550 hp and about 100 kg less weight than the M4 Competition. In 2023 came a modern 3.0 CSL, limited to 50 cars, with a manual gearbox.
CS and the modern CS models
The letters CS have a long history at BMW. In the 1960s and 1970s, CS was used for elegant coupés, such as the 2800 CS and 3.0 CS, and is usually understood as "Coupé Sport".
In recent years, BMW M has used CS for special versions that sit between the Competition models and the most extreme cars. A modern CS usually has more power than the Competition, less weight thanks to carbon parts, a sharper chassis and special details, but it remains suitable for everyday use.
Well-known modern CS models include:
- M4 CS (F82) and M3 CS (F80) with 460 hp.
- M2 CS (F87) with 450 hp, the most powerful version of the first M2.
- M5 CS (F90) with 635 hp, the most powerful M5 until the hybrid G90.
- M3 CS (G80) and M4 CS (G82) with 550 hp.
CS models are usually built for a limited time and are popular with collectors.
GTS: the track specials
GTS is used for the most track-focused road cars from BMW M. These cars often have roll cages or rear seat delete, adjustable suspension, large wings and very limited production.
The first modern GTS was the E92 M3 GTS of 2010. It had a larger 4.4-litre V8 with 450 hp, a stripped interior, a roll bar and an adjustable rear wing. Only a small number were built, and it is extremely rare today.
The M4 GTS of 2016 followed with 500 hp from its turbocharged six-cylinder engine. It used water injection to cool the intake air, had carbon parts, adjustable suspension and a large rear wing. Around 700 were built.
GTS cars are designed for the race track. They are fast, loud and uncompromising, and they show what BMW M can do when everyday comfort is not the priority.
Competition: more performance for more drivers
The word Competition started as an option package. On the E46 M3, the Competition Package added larger wheels, faster steering and improved brakes. On later models such as the F10 M5, the F80 M3 and F82 M4, the Competition Package also added more power and a sportier chassis.
From around 2018, BMW M began to sell Competition versions as separate models, such as the M5 Competition, the M3 Competition and the M4 Competition. In many markets, the Competition became the main version of these cars.
A Competition model usually has more power than the standard car, a stiffer chassis, black exterior details, special wheels and, in some cases, sportier seats.
Competition models are not limited editions. They are an easier way to get more performance than the standard car, without the price and rarity of a CS or CSL.
How to judge a special BMW M car
Special BMW M cars are often bought as collector cars, so their originality and history are very important.
- Check that the car is genuine. Use a VIN decoder to confirm the model and the original options. Some cars are converted to look like special versions.
- Look for complete records. Documents, invoices and the original paperwork add value.
- Check the special parts. Carbon parts, special seats, wheels and wings are expensive and often unique. Make sure they are present and in good condition.
- Mileage and condition have a big effect on value, but a well-used car with full history can still be a great buy for a driver.
- Get a specialist inspection, especially for very rare cars.
The badge is only valuable if the car behind it is right.
Are special M cars a good investment?
Many special BMW M cars have kept or increased their value over the years. The E46 M3 CSL, the E92 M3 GTS and the M4 GTS are good examples: limited numbers, a strong story and a special driving experience made them sought after by collectors.
But not every special edition becomes a classic, and past prices are no guarantee for the future. Values depend on many factors: how many cars were built, how special they are to drive, their condition, the mileage and the general market for classic and modern performance cars.
Running costs also matter. Special parts, such as carbon components, special seats and wheels, can be very expensive to replace, and some cars need specialist care.
The best approach is to buy a special M car because you love it and want to drive it, not only as an investment. If you choose a well-documented, original car and look after it properly, you will enjoy it, and it is likely to remain desirable.
