The powertrain: Engine range expanded further

Sep 8, 2015
The A 160 rated at 75 kW (102 hp) is the new entry-level model of the A-Class model range. Also new are the especially efficient diesel models A 180 d BlueEFFICIENCY Edition with CO2 emissions of 89 g/km and the versions of the dynamic models A 250 and A 250 Sport with manual gearbox. The A 220 d now has a slightly higher output of 130 kW (177 hp), an increase by 5 kW (7 hp), while the Sport models A 250 Sport and A 250 Sport 4MATIC now develop 160 kW (218 hp) instead of 155 kW (211 hp) previously. The Mercedes-AMG A 45 4MATIC also benefits from the model update. With a peak output of 280 kW (381 hp) and maximum torque of 475 Nm, the entry-level model from Mercedes-AMG is the world's most powerful compact sports model. In combination with the 7G-DCT dual-clutch transmission, the A-Class now has "Launch Assist" for even faster acceleration from standstill. All in all, the model range counts 17 variants.
Mercedes-Benz is also using the A-Class model update as the opportunity to introduce the new nomenclature for the drive variants in this model series. While the petrol models remain without an additional letter, the lower-case "d" replaces the "CDI" designation. For example, the A 200 CDI is now called the A 200 d.
The model range of the A-Class now features an attractive new entry-level model in the A 160. Its four-cylinder engine develops 75 kW (102 hp) from a displacement of 1595 cc and produces a peak torque of 180 Nm from 1200 rpm. Equipped with the 7G-DCT dual-clutch transmission, the A 160 consumes just 5.1 litres of premium petrol per 100 kilometres (with manual gearbox: 5.4 l/100 km). This corresponds to CO2 emissions of just 119 grams per kilometre (with manual gearbox: 124 g/km).
The new efficiency champion is the 80 kW (109 hp) A 180 d BlueEFFICIENCY Edition, which is happy with an NEDC fuel consumption of just 3.5 l/100 km. The CO2 emissions of outstandingly low 89 g/km come courtesy of numerous measures to enhance efficiency. For example, the comfort suspension with ride-height lowering and aerodynamically styled steel wheels ensures further improved aerodynamics. The smaller fuel tank with a capacity of 40 litres saves weight. The manual gearbox has longer gear ratios and consequently helps to save fuel, as do the tyres with optimised rolling resistance and elevated air tyre pressure.
The dynamic models A 250 and A 250 Sport rated at 155 kW (211 hp) and 160 kW (218 hp) are now also available with a manual gearbox. The performance of the vehicles is on the level of sports cars with a top speed of 240 km/h and a sprint time from rest to 100 km/h of 6.5 and 6.4 seconds, respectively.
The Mercedes-AMG A 45 4MATIC also benefits from the model update. With a maximum output of 280 kW (381 hp) and a peak torque of 475 Nm, the entry-level model from Mercedes-AMG is the world's most powerful compact sports model. This power pack delivers a dynamic performance that is unrivalled: it accelerates from rest to 100 km/h in just 4.2 seconds. This means that the new Mercedes-AMG A 45 takes 0.4 seconds less for this exercise than its predecessor. At the same time, fuel consumption has been kept at the previous level: no other high-performance model in this category can match its NEDC minimum fuel consumption of 6.9 litres per 100 kilometres (corresponds to 162 g/km CO2).
The new "Launch Assist" function delivers maximum acceleration and is a standard feature in conjunction with the 7G-DCT dual-clutch transmission. To activate the function, the driver has to push the "ESP off" button, select the SPORT or MANUAL transmission mode, keep the brake pedal depressed while applying full throttle at the same time. Upon releasing the brake, the A-Class will accelerate at full engine power and without losing grip. The proper gears are selected fully automatically independent of the activated transmission mode.
The engine, transmission and steering characteristics of the A-Class can now be adjusted at the touch of a button with the optional extra DYNAMIC SELECT. Drivers can choose from four driving programmes: Comfort, Sport, Eco and Individual (for details about DYNAMIC SELECT, please see the chapter "Chassis"). Independent of the driving programme, drivers can access the "ECO display" on the multifunction display, which helps them to adopt an even more environmentally friendly driving style.
