The Mercedes 190E 2.3-16 and its successor, the 2.5-16, are some of the most sought-after models produced by the German marque. Originally intended to be a rally car, the 190E 2.3 was redirected to the DTM German touring car series due to the arrival of the Audi Quattro, which had more technically advanced four-wheel drive. DTM rules required there to be a road-going version, and thus the 190E 2.3-16 Cosworth was born.
The standard 190E used a 2.3-litre four-cylinder engine that produced an underwhelming 134bhp. However, after reworking by Cosworth, it could rev to 7000rpm and produce an impressive 182bhp and 174lb ft of torque. These reserves enabled the car to accelerate to 62mph in 7.5 seconds and reach a top speed of 143mph. The power was sent to the rear axle via a five-speed manual gearbox that had a racing shift pattern, with first on a dog leg, left and down from neutral.
Cosworth’s expertise wasn’t limited to the drivetrain; it also worked closely with Mercedes’ engineers on the suspension and handling components. The steering ratio was shortened, and the steering wheel was made smaller, resulting in fast and responsive handling. The wider wheel arches, side skirts, and rear spoiler gave the 190E 2.3 a sleek but menacing appearance.
In 1988, Mercedes unveiled a new version, the 2.5, which came with a 2.5-litre engine that produced 201bhp and 181lb ft of torque. This version of the Cosworth completed in various championships before being entered into the DTM, which meant a new road-going version was required. The legendary 2.5-16 EVO I limited edition was born, with only 502 ever made it to public roads, all LHD.
As brilliant as they were, the 2.3-16 and 2.5-16 had drawbacks. They were notorious for high running costs, and owners had to be vigilant about regular maintenance or pay the consequences. The body kit looked great but was prone to cracking and fading over time, leading to costly repairs.
Despite these quirks, driving a 190E 2.3-16 or 2.5-16 as it was intended to be driven is a thoroughly rewarding experience. These cars deliver strong performance, precise handling, and a sense of high-quality engineering mixed with luxurious features and a sleek yet purposeful appearance. If you ever get the chance to drive or own one, don’t hesitate. You won’t be disappointed.
## The Cosworth Touch
Cosworth has a track record of delivering the goods when it comes to motorsport and fast road cars. Many companies have called on its expertise over the years, including Mercedes in the 1980s. The result was the sought-after 190E 2.3-16 and its successor, the 2.5-16.

## Buyer Beware
When considering purchasing a Mercedes 190E 2.3-16 or 2.5-16, there are some things to keep in mind.
### Engine
It’s important to thoroughly check the fuel pump for leaks. Additionally, the engine’s idle should be around 900-1000rpm, with a slight rattle known as ‘cam clutter’ being a common occurrence. However, excessive rattling on start-up could indicate a need for timing chain replacement. It’s also important to ensure that the engine runs smoothly all the way up to the redline, with no hesitations or issues. If the car is not idling correctly, vacuum leaks in the rubber hoses around the injection system could be a potential cause. These issues can be addressed through regular maintenance and careful monitoring of the engine’s performance.
### Steering
There are no common problems reported with the steering, although some owners say they have experience of issues with the power steering pump.
### Brakes
Brake fluid leaks are common, often manifesting as a spongy brake pedal.
### Suspension
The 190E is known for its sturdy chassis, but beware of corrosion. Keep an eye out for frame damage from accidents, too. The shock absorbers can leak, often resulting in a rather bumpy ride. Also check the ball joints, which often wear out and fail, causing the front suspension to collapse.
### Interior
The screen on the lap timer can bleed, and the door cards tend to lift away at the top. Check the visor area and the vinyl roof panel for dampness or discoloration. The draining system on these cars makes it easy for water to leak down the back of the A-pillar.
## Conclusion
Despite their quirks and high running costs, the Mercedes 190E 2.3-16 and 2.5-16 are highly respected cars for good reason. They deliver strong performance, precise handling, and a sense of high-quality engineering mixed with luxurious features and a sleek yet purposeful appearance. If you ever get the chance to drive or own one, don’t hesitate. You won’t be disappointed.
