Mercedes-Benz to use 3-cylinder engines for compact fwd hybrids

Article by Christian A., on March 31, 2014

Mercedes-Benz will fit three-cylinder engines for future hybrid versions of its compact fwd drive vehicles, disclosed Bernhard Heil, chief of powertrain development of Daimler AG. Mercedes' engineers, however, are not keen to the idea of using three-cylinder engines, but its small size will be necessary for transverse-mounted hybrid powertrains.

Heil told Automotive News in an interview that in packaging a hybridized engine in the front end, the four-cylinder engine has its limitations. Since Daimler's rwd vehicles have enough room, they will be fitted with four-cylinder engines and up. Mercedes' C class, E class and S class are designed to contain bigger engines, while a hybrid-four-cylinder combo does not give rise to packaging issues.

According to Heil, Daimler also intends to offer a small gasoline engine developed jointly with Renault. Mercedes already offers a slightly modified 1.5-liter turbo-diesel engine from Renault in compact cars marketed in Europe. Both the three-cylinder engine and the four-cylinder engine Daimler is co-developing with Renault are designed to be contained into the compact A class, B class, CLA and GLA.

The engines are expected to debut in the next two year, but it remains unclear whether they would be launched in the United States. Mercedes models bound for US are typically run by the most powerful engines in its lineup.

Advanced design, serene every day motoring, and off-road capable: as a nomad between automotive types, the GLA notably reimagines compact SUVs. It masters surefootedly everyday challenges while still being amply robust to go off-road.

The initial Mercedes-Benz in the quickly growing compact SUV group is easily controllable in the city (4417 L x 1804 W x 1494 H in millimetres), energetic on country roads, and efficiently vibrant on highways (Cd figure 0.29). The superior features, developed with great attention to detail, and the adaptable cabin position the GLA clearly as a premium compact SUV.

The GLA is Mercedes-Benz’s first SUV to come with its new permanent all-wheel drive system 4MATIC, with fully adjustable torque distributions.

The new GLA completes Mercedes-Benz’s extensive SUV range. With five series (GLA, GLK, ML, GL and G), it offers the broadest range from any premium European manufacturer, and it meets all the unique driving wishes from customers.

Simultaneously, the GLA is fourth of five new compact Mercedes-Benz models. The sales abundantly show how well customers are receiving these new compacts: In the first six months of 2013, 173,362 A and B-Class units and the all-new CLA Coupé were delivered globally (+58.0%). Particularly rewarding is the high reach rate of the brand-new A-Class: almost half of the European buyers come from other brands.
