1986-1988 Renault 11 (BC37) 1.7 (BC37N) (88 Hp)

The Renault 11, specifically the 1.7 (B/C37N) variant producing 88 horsepower, was a key model in Renault’s lineup during its 1986-1988 production run. Falling within the B/C37 series, this iteration represented a mid-cycle refresh of the original Renault 11, aiming to broaden its appeal with a more refined engine option. Positioned as a step up from the base 1.4-liter models, the 1.7 offered a balance between performance and affordability, targeting buyers seeking a comfortable and practical hatchback for everyday use. It was a significant player in the European small family car segment, competing with vehicles like the Peugeot 205, Citroën AX, and Ford Escort.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Renault 11 1.7 was the F2N engine, a 1.7-liter inline-four cylinder gasoline engine. This engine was a significant upgrade over the smaller displacement options available in the 11 range. It featured a cast iron block and an aluminum cylinder head, a common configuration for engines of this era. The F2N utilized a single overhead camshaft (SOHC) valvetrain, operating two valves per cylinder. Fuel delivery was managed by a Bosch mechanical fuel injection system, a step towards improved efficiency and emissions control compared to carburetors. While not as sophisticated as later multi-point injection systems, it provided a noticeable improvement in driveability. The engine produced 88 horsepower at approximately 5,500 rpm and 138 Nm (102 lb-ft) of torque at 3,500 rpm. The transmission paired with the 1.7-liter engine was typically a four-speed manual, but a three-speed automatic transmission was also offered, though less common. The automatic transmission, while providing convenience, did impact acceleration and fuel economy.

Driving Characteristics

The Renault 11 1.7 offered a noticeable improvement in performance compared to the 1.4-liter models. The extra displacement and slightly higher compression ratio resulted in more readily available torque, making it more comfortable for highway cruising and overtaking maneuvers. With the manual transmission, the 0-60 mph time was estimated to be around 11-12 seconds, respectable for a car of its class in the late 1980s. The automatic transmission, however, added approximately 1-2 seconds to this time. The gear ratios were relatively tall, prioritizing fuel economy over outright acceleration. The steering was light and precise, making it easy to maneuver in urban environments. The suspension, while comfortable, wasn’t particularly sporty, leaning towards a softer ride quality. Compared to the more powerful Renault 11 TXE models, the 1.7 felt less eager to rev, but offered a more relaxed and refined driving experience.

Equipment & Trim Levels

The Renault 11 1.7 typically came equipped with a reasonable level of standard features for its time. These included cloth upholstery, a basic stereo system, and manual windows and door locks. The dashboard layout was functional and straightforward, with clearly labeled controls. Optional extras included a sunroof, upgraded stereo systems, and central locking. The trim level often dictated the exterior detailing, with higher-spec models featuring body-colored bumpers and door handles. The 1.7 occupied a middle ground in the Renault 11 lineup, offering more comfort and features than the base models but lacking the premium appointments of the TXE. Interior space was adequate for a small family car, with sufficient headroom and legroom for passengers.

Chassis & Braking

The Renault 11 utilized a relatively simple chassis design, featuring a front-wheel-drive layout and a MacPherson strut front suspension. The rear suspension employed a torsion beam setup, which was cost-effective and provided a reasonable level of ride comfort. Braking was typically accomplished with disc brakes on the front wheels and drum brakes on the rear. The braking system was adequate for normal driving conditions, but lacked the stopping power of more modern systems. Stabilizer bars were fitted to both the front and rear axles, helping to reduce body roll during cornering. The overall weight of the vehicle, around 950-1000 kg (2094-2205 lbs), contributed to its relatively nimble handling.

Market Reception & Comparison

The Renault 11 1.7 was generally well-received by automotive critics as a practical and affordable family car. It was praised for its comfortable ride, decent performance, and relatively low running costs. However, some critics noted that the interior was somewhat dated and lacked the sophistication of some of its rivals. Compared to the 1.4-liter models, the 1.7 offered a significant improvement in performance and refinement. Compared to the higher-spec TXE models, it represented a more sensible value proposition for buyers who didn’t require the extra power or luxury features. Fuel economy was a strong point, averaging around 35-40 mpg in mixed driving conditions. Reliability was generally good, although the Bosch fuel injection system could occasionally require maintenance.

Legacy

The Renault 11 1.7, while not a particularly rare or collectible model today, remains a popular choice among classic car enthusiasts and those seeking an affordable and reliable vintage hatchback. The F2N engine is known for its durability and relative simplicity, making it relatively easy to maintain. Parts availability is generally good, although some components may be becoming increasingly difficult to find. The 1.7 variant offers a good balance between performance and economy, making it a practical choice for everyday use. In the used car market, well-maintained examples of the Renault 11 1.7 can still command reasonable prices, reflecting its enduring appeal as a classic European hatchback. It represents a significant piece of Renault’s history and a testament to the enduring popularity of the small family car segment.
