The Vauxhall Corsa D 1.4T (120 hp) S&S, produced from 2012 to 2014, represented a mid-range offering within the fourth generation (Corsa D) of the popular British supermini. Positioned above the base 1.0L and 1.2L models, and below the more potent 1.6L variants, the 1.4T aimed to provide a balance of performance, fuel efficiency, and equipment. It was a key component of the Corsa D lineup, which itself was based on the General Motors Gamma platform (also known as the 1HX0/A3 platform), shared with models like the Opel Corsa and Fiat Grande Punto. The “S&S” designation indicates the inclusion of a Start & Stop system, designed to improve fuel economy in urban driving conditions.
Powertrain & Engine Architecture
The heart of the Corsa D 1.4T S&S is the A14NEL engine, a 1.4-liter inline-four cylinder gasoline engine featuring a turbocharger and intercooler. This engine produced 120 horsepower at 6000 rpm and 175 Nm (129.07 lb-ft) of torque at 4800 rpm. The engine boasts a displacement of 1364 cm³ (83.24 cubic inches) with a bore of 72.5 mm (2.85 inches) and a stroke of 82.6 mm (3.25 inches). It utilizes a compression ratio of 9.5:1 and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. Fuel delivery is managed by a multi-port manifold injection system. The turbocharger, a key component in boosting power output, provides increased air intake to the engine, enhancing both performance and efficiency.
The 1.4T engine was typically paired with a five-speed manual transmission, however, an optional six-speed automatic transmission was also available. The automatic transmission was designed to provide smoother gear changes and enhanced convenience, particularly in city driving. The automatic’s gear ratios were tuned to balance acceleration with fuel economy, though it generally resulted in slightly slower 0-60 mph times compared to the manual version. The engine oil capacity is 4 liters (4.23 US quarts / 3.52 UK quarts), and the recommended oil specification is dependent on the specific market and Vauxhall’s recommendations at the time of production.
Start & Stop System
The “S&S” designation refers to the inclusion of a Start & Stop system. This system automatically shuts off the engine when the vehicle comes to a complete stop (e.g., at a traffic light) and restarts it instantly when the driver depresses the clutch pedal (manual transmission) or releases the brake pedal (automatic transmission). This feature significantly reduces fuel consumption and emissions in stop-and-go traffic.
Driving Characteristics
The Corsa D 1.4T S&S offered a noticeable step up in performance compared to the lower-displacement engines in the range. Acceleration from 0-60 mph was around 9.8 seconds (calculated by Auto-Data.net), and 0-100 km/h took approximately 10.3 seconds. The turbocharger provided a boost in mid-range torque, making overtaking maneuvers easier and more confident. While not a particularly sporty vehicle, the 1.4T offered sufficient power for everyday driving and occasional highway trips. Compared to the 1.6L models, the 1.4T felt less eager to rev, but the turbocharger compensated for this with its readily available torque. The automatic transmission, while convenient, could sometimes feel slightly hesitant during downshifts, and didn’t offer the same level of driver engagement as the manual gearbox.
The car achieved a maximum speed of 195 km/h (121.17 mph). Fuel economy figures were respectable for the time, with combined fuel consumption rated at 5.5 l/100 km (42.8 US mpg / 51.4 UK mpg / 18.2 km/l). Urban fuel consumption was 7.2 l/100 km (32.7 US mpg / 39.2 UK mpg / 13.9 km/l), while extra-urban consumption was 4.5 l/100 km (52.3 US mpg / 62.8 UK mpg / 22.2 km/l).
Equipment & Trim Levels
The Corsa D 1.4T S&S was typically offered in several trim levels, including Energy, Excite, and Sportive. Standard equipment generally included air conditioning, power steering, electric front windows, a CD/MP3 stereo system, and ABS brakes. Higher trim levels added features such as alloy wheels, a trip computer, remote central locking, and electric door mirrors. Optional extras included a panoramic sunroof, parking sensors, and upgraded audio systems. Interior upholstery was typically cloth, with higher trims offering more premium fabric options. The dashboard layout was functional and straightforward, with a clear instrument cluster and logically placed controls.
Chassis & Braking
The Corsa D 1.4T S&S utilized a front-wheel-drive layout with a MacPherson strut front suspension and a torsion beam rear suspension. This suspension setup provided a comfortable ride quality, although it wasn’t particularly sporty. The front brakes were ventilated discs, while the rear brakes were drums. ABS (Anti-lock Braking System) was standard, providing enhanced braking performance and stability. The car rode on 185/65 R15 tires with 15-inch wheel rims. The weight-to-power ratio was 9.1 kg/hp, and the weight-to-torque ratio was 6.2 kg/Nm.
Market Reception & Comparison
The Corsa D 1.4T S&S was generally well-received by automotive critics as a competent and practical supermini. It was praised for its fuel efficiency, comfortable ride, and relatively strong performance. However, some critics noted that the interior felt somewhat dated compared to rivals, and the handling wasn’t as engaging as some other cars in its class. Compared to the 1.0L and 1.2L models, the 1.4T offered a significant improvement in performance, making it a more suitable choice for drivers who frequently travel on highways or carry passengers. Compared to the 1.6L models, the 1.4T offered a better balance of performance and fuel economy, making it a more sensible option for everyday use. Reliability was generally good, although some owners reported minor issues with the Start & Stop system.
