Sporty, stylish, intelligent and dynamic: The newCLA 35 is the latest point of entry to the world of Mercedes-AMG. The four- door coupe shares the progressive technology with the A-Class, but is even bolder with its iconic design and the intelligent MBUX interior assistant.The high torque 2.0L Inline-4 turbo engine delivers 302 hp, distributed to all four wheels via the 7-speed dual-clutch transmission and variable all- wheel drive. Sporty driving performance (acceleration from 0-60 mph in 4.6 seconds est.) is combined with a range of versatile driving experiences – from very sporty to refined and comfortable on long journeys.
New four-cylinder turbo engine with 302 hp
The 2.0L Inline-4 turbo engine is a new development and is based on the M260 four-cylinder engine in the new A-Class. The new drive boasts a quick response to accelerator pedal commands, high torque (295 lb-ft max. torque from 3,000 rpm), a lively response and an emotional engine sound. The crankcase made of high-strength, lightweight die-cast aluminum reduces the vehicle weight where it matters most for driving dynamics.
The twin-scroll turbocharger combines optimum responsiveness at low engine speeds with a significant power increase at higher engine speeds. The housing of the twin-scroll turbocharger is divided into two parallel ducts. Together with two separate ducts in the exhaust manifold, this makes it possible to channel the exhaust gases separately on the turbine wheel.
This results in a further advantage of twin-scroll technology — minimization of the mutually adverse effects of the individual cylinders on the gas cycle. The exhaust gas backpressure is reduced and gas exchange and engine efficiency are improved.
Numerous engine measures increase efficiency
The high technological standards of the new four-cylinder engine are also underscored by numerous efficiency-enhancing measures. These include CAMTRONIC variable valve control, intelligent thermal management for 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.
Agile gear ratios: AMG SPEEDSHIFT DCT 7-Speed Transmission
The AMG SPEEDSHIFT DCT 7-Speed Transmission also contributes to the agile and dynamic character of the new CLA 35. The gear ratios are configured so that the driver experiences very responsive acceleration in all speed ranges, combined with fast shifting and optimum connections when upshifting.
The standard RACE-START function allows maximum acceleration from a stationary position and is a high performance experience. The functions of the AMG SPEEDSHIFT DCT 7-Speed transmission also include a temporary manual shift mode activated by operating the steering wheel shift paddles in any driving mode, and with the manual transmission mode “M”for manual gear changes with the shift paddles.
AMG Performance 4MATIC variable all-wheel drive
Dynamism, agility and performance – these three attributes characterize the standard all-wheel drive of the new Mercedes-AMG CLA 35. The variable AMG 4MATIC+ combines the best possible traction with driving pleasure. The torque distribution is variable to suit the dynamic handling requirements. The spectrum ranges from front-wheel drive only to a 50:50 percent distribution to the front and rear axles.
A multi-disc clutch that is integrated in the rear axle transmission is responsible for the variable torque distribution between the front and rear axles. It is controlled electro-mechanically. The influencing factors for torque distribution are the driving speed, the lateral and longitudinal acceleration and the steering angle, and the difference in rotational speed between the individual wheels, the gear selected and the accelerator position.
The main advantages of electro-mechanical control over an electro-hydraulic system relate to more refined driving dynamics – primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range.
As long as ESP® is activated, the 4MATIC+ system stays in “Comfort”mode. As soon as the driver presses the “ESP® SPORT Handling”or “ESP® OFF”button, the 4MATIC+ system switches to “Sport”mode – for even more agile handling and even higher stability limits.
Five driving programs: vehicle characteristics with a wide spread
The five AMG DYNAMIC SELECT drive programs “Slippery,””Comfort,””Sport,””Sport +”and “Individual”enable a wide range of vehicle characteristics from comfortable to dynamic. They change relevant parameters, such as the responsiveness of the engine and transmission.
The new “Slippery”drive program is optimized for low-grip, icy road conditions, with reduced power and a flat torque curve. Smooth gear changes and earlier upshifts support a more stable driving character.
The “Comfort”program stands for comfortable and fuel-efficient driving, for example, thanks to early upshifts. Suspension and steering are set up for an emphasis on comfort.
“Sport”and “Sport+”place the focus on agility and driving pleasure with sporty engine and transmission tuning. The sound of the turbo engine is more striking. “Sport+”is particularly exciting with double-declutching during downshifts and partial cylinder cut-off via a brief and precisely defined retardation of ignition and injection at full load.
The “Individual”drive program enables specific parameters to be selected and saved according to personal preferences. In addition, the gliding function is available in the “Reduced”and “Moderate”drive settings.
