The Renault 21 2.0i Turbo, produced between 1989 and 1994, represented the performance pinnacle of the B48 generation Renault 21 lineup. Positioned as the flagship model, it offered a significant step up in power and driving experience compared to the more common 1.7 and 2.0-liter naturally aspirated versions. The 21, launched in 1986, was Renault’s replacement for the successful Renault 18, aiming to provide a more modern and spacious family sedan. The B48 series, specifically, benefited from styling updates and mechanical refinements throughout its production run, with the 2.0i Turbo serving as the halo model appealing to enthusiasts seeking a sporty and refined driving experience in a practical package.

Powertrain & Engine Architecture
The heart of the Renault 21 2.0i Turbo was the J7R 756 engine, a 1995cc inline-four cylinder powerplant. This engine featured a single overhead camshaft (OHC) valvetrain with two valves per cylinder. Crucially, it was equipped with a Garrett turbocharger and multi-port fuel injection, allowing it to produce 162 horsepower at 5500 rpm and 260 Nm (191.77 lb-ft) of torque at 3000 rpm. The 8.5:1 compression ratio was a compromise between performance and reliability, typical for a turbocharged engine of the era. The engine’s transverse mounting and front-wheel-drive configuration were standard for Renault at the time. The five-speed manual transmission was the only gearbox option offered with this engine, designed to handle the increased power output.
Driving Characteristics
The 2.0i Turbo offered a noticeably more engaging driving experience than its naturally aspirated siblings. Acceleration to 60 mph was achieved in approximately 7.7 seconds, and it boasted a top speed of 137.94 mph. The turbocharger provided a surge of power in the mid-range, making overtaking maneuvers effortless. While not a particularly refined engine in terms of noise or vibration, it delivered strong performance for its time. The five-speed manual transmission was well-matched to the engine’s characteristics, offering precise shifts and allowing the driver to maintain optimal power delivery. Compared to the 1.7L or 2.0L versions, the Turbo model felt significantly more responsive and capable, though the turbo lag was noticeable at lower engine speeds.
Equipment & Trim Levels
The 2.0i Turbo typically came with a higher level of standard equipment than the lower-spec Renault 21 models. This included features like central locking, electric windows, power steering, and an upgraded interior trim. Upholstery was generally cloth, but leather options were available. Air conditioning was a common, though not always standard, feature. Optional extras included a sunroof, upgraded audio systems, and alloy wheels. The dashboard layout was typical of Renaults of the period, featuring a functional and straightforward design. The instrument cluster included a boost gauge, reflecting the turbocharged nature of the engine.
Chassis & Braking
The Renault 21 2.0i Turbo utilized a relatively simple suspension setup, consisting of MacPherson struts at the front and a torsion beam at the rear. The suspension was tuned to provide a balance between comfort and handling, leaning towards the former. Braking duties were handled by ventilated discs at the front and solid discs at the rear, supplemented by an anti-lock braking system (ABS) which was becoming increasingly common on European cars of this era. The steering was rack and pinion, providing reasonably precise control. The 195/55 R15 tires offered adequate grip for the car’s performance capabilities.
Market Reception & Comparison
The Renault 21 2.0i Turbo was generally well-received by automotive critics, who praised its performance and value for money. It was seen as a credible alternative to other European family sedans, such as the Ford Sierra and Opel Vectra. However, some critics noted the engine’s lack of refinement and the somewhat dated interior design. Compared to the naturally aspirated 2.0-liter model, the Turbo offered a substantial performance boost, but at the cost of slightly increased fuel consumption. The 1.7L models were significantly more economical but lacked the performance of the Turbo. Reliability was generally good, although turbocharger issues could occasionally arise with improper maintenance.
Legacy
The Renault 21 2.0i Turbo remains a fondly remembered car among enthusiasts. While not a particularly rare vehicle, well-maintained examples are becoming increasingly sought after. The J7R engine, while not known for being exceptionally durable, is relatively straightforward to work on, making it a popular choice for classic car restorers. Today, the 21 2.0i Turbo represents a piece of 1990s French automotive history, offering a unique blend of performance, practicality, and affordability. Its legacy lies in providing a spirited driving experience in a comfortable and spacious package, cementing its place as the performance leader of the B48 Renault 21 range.
