The Mercedes 190E Cosworth
In the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA' by Cosworth". During this time, the Audi Quattro with its all-wheel drive and turbocharger was launched, making the 2.3-16v appear outclassed. With a continued desire to compete in high-profile motor sport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motor sport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high-performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at the Nardo testing facility in Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records. The Mercedes 190-E Cosworth was also featured on the second episode in series fifteen of the popular car show Top Gear.
An enlarged 2.5 L engine replaced the 2.3 L in 1988. It offered double-row timing chains to fix the easily snapping single chains on early 2.3 engines, and increased peak output by 17 hp (12.5 kW) with a slight increase in torque. For the European market without catalyst (RÜF) the car delivered 204 bhp (150 kW). Catalyst equipped 2.5-16s produced a slightly reduced 197 bhp (147 kW). It is debated whether the 2.5 L engine was developed and built by Mercedes or Cosworth. Mercedes were not keen to broadcast the fact that their most sporting saloon car had an engine developed by a British company. However some cylinder heads from 2.5 L cars are stamped with the Coscast logo indicating they were cast at Cosworth's foundry just like the 2.3s. Cosworth also list the project code "WAB" for the development of the 2.5-16-valve head just as they do for the 2.3-16-valve head.
Due to their performance, the 16-valve cars were different from the other 190 models. The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four-door saloon of the time, whilst also reducing lift at speed. The steering ratio was quicker and the steering wheel smaller than that on other 190s, whilst the fuel tank was enlarged from 55 to 70 L. The Getrag 5-speed manual gearbox was unique to the 16-valve and featured a 'racing' gear pattern with 'dog-leg' first gear, left and down from neutral. This meant that the remaining 2nd, 3rd, 4th and 5th gears were in a simple H pattern allowing fast and easy selection. The gearchange quality was, however, noted as "notchy, baulky", criticisms which weren't levelled at the BMW M3 (E30) which shared the same gearbox. The pattern is also unusual in that the driver engages reverse by shifting left and up from neutral, as for first gear in a conventional pattern. This was demonstrated in a Top Gear episode (S15E02) where James May took a 190 E 2.3-16 Cosworth and repeatedly confused reverse and first gear. An oil cooler was fitted to ensure sufficient oil cooling for the inevitable track use many of these cars were destined for.
The strictly four-seater interior had Recaro sports seats with strong side bolsters for front and rear passengers. 3 extra dials - an oil temperature gauge, stopwatch and voltmeter - were included in the centre console. The 190 E 2.3-16 was available in only two colours, Blue-Black metallic (Pearl Black in the US), and Smoke Silver. The 2.5-16 added Almandine Red and Astral Silver.
All 2.3-16-valve 190 models are fitted with a Limited Slip Differential (LSD) as standard. They were also available with Mercedes' ASD system which was standard equipment on the 2.5-16v. The ASD is an electronically controlled, hydraulically locking differential which activates automatically when required. The electronic control allows varied amounts of differential lock from the standard 15% right up to 100%. It is not a traction control system however, and can only maximize traction rather than prevent wheel spin. Activation of the ASD system is indicated by an illuminating amber triangle in the speedometer.
The suspension on 16-valve models is very different from the standard 190 (W201). As well as being lower and stiffer, it has quicker dampers, larger anti-roll bars, harder bushings and hydraulic Self-levelling suspension (SLS) on the rear. This allows the rear ride height to remain constant even when the car is fully loaded.
At the inauguration of the new, shorter Nürburgring in 1984, a race with identical cars was held, with former and current F1 pilots at the wheel. A then unknown Ayrton Senna took first place.
Private Teams such as AMG later entered the 2.3-16 in touring cars races, especially the DTM. In the late 1980s, the 2.5-16 (never released in the United States) raced many times, against the similar BMW M3 and even the turbocharged Ford Sierra RS Cosworth.
