The engines: Four and 4x4

Feb 10, 2014
Initially the power range of the 1.6 and 2.0-litre petrol engines will extend from 115 kW (156 hp) in the GLA 200 to 155 kW (211 hp) in the GLA 250. The two diesel engines excel with dynamic torque and outstanding efficiency: the two choices are the GLA 200 CDI with 100 kW (136 hp) and the GLA 220 CDI with 125 kW (170 hp). With the exception of the basic petrol engine, all engines can be combined with 4MATIC all-wheel drive. All the engines feature the ECO start/stop function and comply with the Euro 6 emissions standard.
The basis for the two petrol engine variants in the new GLA-Class is the all-aluminium M 270 engine with two chain-driven overhead camshafts and four-valve technology. In the new GLA-Class the M 270 is available in two output ratings. The GLA 200 with a displacement of 1595 cc develops 115 kW (156 hp) and maximum torque of 250 Nm, which is available from 1250 to 4000 rpm. It sprints from zero to 100 km/h in 8.9 seconds and has a top speed of 215 km/h, but gets by on an average of 5.9 l/100 km of fuel, meaning CO2 emissions of 137 g/km.
The GLA 250 is powered by the top engine variant with a displacement of 1991 cc. The engine develops 155 kW (211 hp) and maximum torque of 350 Nm from 1200 to 4000 rpm. The GLA 250 is optionally available also as 4MATIC version. Performance is at sports car level, with acceleration from zero to 100 km/h in 7.2 (7.1) seconds and a top speed of 235 (230) km/h (figures for 4MATIC version in brackets). Nonetheless it has the best fuel consumption in this class at 6.0 (6.5) l/100 km and CO2 emissions of 141 (151) g/km.
Agile right from low speeds: the diesel engines
Dynamic in its handling, extremely efficient and of exemplary cleanliness: the GLA 220 CDI, available exclusively in combination with the 7G-DCT dual clutch transmission. The 125 kW (170 hp) top diesel variant, with a displacement of 2.2 litres and peak torque of 350 Nm, features a weight-optimised crankshaft and, with its individual bearing covers bolted from below and four counterweights, weighs around six kilograms less than an OM 651 of the same displacement, in the longitudinal-installation variant. The GLA 220 CDI is equipped with a multi-path exhaust gas recirculation system which reduces nitrogen oxide emission levels.
With 115 (129) g CO2 per kilometre and a combined fuel consumption of 4.4 (4.9) litres per 100 km, the GLA 220 CDI sets new standards in its segment (figures for 4MATIC version in brackets). Performance characteristics: 8.3 (8.3) seconds for the standard sprint and a top speed of 215 (215) km/h.
At 2.2 litres, the engine has a relatively large displacement, which makes it agile right from low speeds. Mercedes-Benz engine experts call this combination of large-displacement engine and low engine speeds "downspeeding". As a result it has been possible to make the ECONOMY mode of the 7G-DCT transmission decidedly economical and comfortable. If the driver selects transmission mode "S", gearshifts are performed much faster and the ratio spread uses the rpm reserves of the engine for dynamic performance.
The engine of the GLA 200 CDI has the same displacement, while the maximum output is 100 kW (136 hp) and the maximum torque 300 Nm. This engine has been reengineered for greater efficiency. The modifications include optimisation of the belt drive, a cylinder head package with different roller bearings and additional finishing, optimisation of the vacuum pump, aluminium pistons with optimised assembly clearances and a low-friction ring package, and the roller bearings of the Lanchester balancer shaft. The combined fuel consumption of 4.3 (4.9) litres of diesel per 100 kilometres is outstanding in this output class (figures for 4MATIC version in brackets).
