The Opel Adam Rocks 1.4 (87 hp) debuted in 2014 as a stylistic and functional extension of the standard Opel Adam. Opel aimed to capture a younger demographic with the Rocks model, offering a vehicle that blended the practicality of a small hatchback with the visual appeal of a mini-SUV. The raised suspension and protective body cladding were key design elements, differentiating it from its more conventional sibling. This 1.4-liter engine and five-speed manual transmission combination represented the base level powertrain option, focusing on affordability and reasonable fuel economy. It was primarily sold in European markets, where the demand for small, stylish city cars was strong.
Powertrain & Engine Architecture
The heart of the Adam Rocks 1.4 was the A14XER engine, a 1.4-liter inline-four cylinder gasoline engine. This engine was a member of Opel’s Family 0 small engine family. It featured multi-point fuel injection and a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. The engine produced 87 horsepower at 4000 rpm and 130 Nm (95.88 lb-ft) of torque at 4000 rpm. The five-speed manual transmission was the standard gearbox for this variant, offering a relatively conventional gear ratio spread. The transmission was a front-wheel drive setup, typical for vehicles in this class. The engine’s design prioritized fuel efficiency and smooth operation over outright performance.
Driving Characteristics
The Adam Rocks 1.4, with its 87 horsepower and five-speed manual transmission, offered adequate, but not exhilarating, performance. Acceleration from 0 to 60 mph took approximately 11.9 seconds, and the top speed was around 109 mph. The engine felt somewhat strained when accelerating hard, particularly when fully loaded or on inclines. The five-speed gearbox was well-matched to the engine’s characteristics, providing reasonable spacing between gears. Compared to higher-output Adam Rocks variants (like those with the 1.0-liter turbo engine), the 1.4-liter felt less responsive. However, the manual transmission allowed for greater driver control and engagement than the optional automatic transmission available on other trims. The raised suspension of the Rocks model provided a slightly more comfortable ride than the standard Adam, absorbing bumps and imperfections in the road more effectively.
Equipment & Trim Levels
The Adam Rocks 1.4 typically came with a decent level of standard equipment, though it was less lavish than higher-spec models. Standard features generally included air conditioning, power windows, central locking, and a basic audio system with USB connectivity. Safety features such as ABS, electronic stability control, and front airbags were also standard. The interior typically featured cloth upholstery and a relatively simple dashboard layout. Optional extras included alloy wheels, a panoramic sunroof, upgraded audio systems, and various styling packages. The interior trim levels were often differentiated by the color and pattern of the cloth upholstery.
Chassis & Braking
The Adam Rocks 1.4 utilized a MacPherson strut front suspension and a torsion beam rear suspension. The torsion beam rear suspension was a cost-effective solution commonly found in vehicles of this class. The “Rocks” variant featured a slightly raised ride height compared to the standard Adam, providing increased ground clearance. The braking system consisted of disc brakes on the front wheels and drum brakes on the rear wheels. The braking performance was adequate for everyday driving, but not particularly sporty. The steering was a rack and pinion system, providing reasonably precise and responsive handling.
Market Reception & Comparison
The Opel Adam Rocks 1.4 was generally well-received by critics as a stylish and practical city car. However, the 1.4-liter engine was often criticized for being underpowered, particularly when compared to the more modern and efficient turbocharged engines offered in competing vehicles. Fuel economy was respectable, averaging around 42.8 US mpg in combined driving. Compared to the higher-output Adam Rocks variants, the 1.4-liter offered a lower purchase price but sacrificed performance. It competed with other small city cars such as the Fiat 500, Volkswagen up!, and Peugeot 108.
Legacy
The Opel Adam Rocks 1.4, while not a performance standout, proved to be a reliable and economical city car. The A14XER engine is known for its durability, and with proper maintenance, it can provide many years of service. On the used car market, the Adam Rocks 1.4 represents an affordable entry point into the small crossover segment. Its stylish design and relatively low running costs continue to appeal to buyers seeking a practical and individualistic vehicle. While no longer in production, the Adam Rocks remains a recognizable and relatively common sight on European roads.
