Mercedes-AMG has introduced a new entry-level performance model. Based on the new Mercedes front-wheel drive platform and powered by a new 2.0-liter four-cylinder turbo engine with output of 306ps, the A35 has been designed for maximum driving dynamics.
“With the introduction of the A45 in 2012, we presented a real benchmark in the compact segment. The demand for our compact models has developed very dynamically in recent years,” said Tobias Moers, CEO of Mercedes-AMG. “This success has encouraged us to further expand our portfolio and place it on a broader footing. With the new A35, we are fulfilling our brand promise of driving performance in every detail and offering thrilling lateral dynamics at the level of today’s A45.”
The 2.0-liter turbo engine is a new development and is based on the M260 four-cylinder engine that is seen in the new A-Class. The new unit has been developed to boast a spontaneous response to accelerator pedal commands, with tractive power of 400Nm torque from 3,000rpm. The crankcase, made of high-strength, lightweight die-cast aluminum, reduces the vehicle weight.
A twin-scroll turbocharger is also used. The system aims to combine optimum responsiveness at low engine speeds with a strong power increase at higher speeds. The housing of the twin-scroll turbocharger is divided into two parallel ducts. Together with two separate exhaust ducts in the exhaust manifold, this makes it possible to channel the exhaust gases separately on the turbine wheel.
The cylinders are divided into two cylinder groups and each is directed onto a turbine flow of the twin-scroll turbine. The cylinder groups are defined based on the ignition sequence. This minimizes the mutually adverse effects of the individual cylinders on the gas cycle. The exhaust gas back pressure is reduced, and gas exchange and engine efficiency are improved.
The new four-cylinder engine is also equipped with numerous efficiency-enhancing measures. These include Camtronic variable valve control, intelligent thermal management for both the engine and oil, high-precision piezo injectors and multi-spark ignition. In production, the patented Conicshape cylinder honing reduces internal engine friction and also increases efficiency.
Paired to the powerplant is the AMG Speedshift DCT 7G dual-clutch transmission. In this application, the gear ratios have been configured for spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up.
