Mercedes-AMG has finally unveiled the tech of its latest, fifth-generation Mercedes-Benz C-Class, the C43 4 Matic. More than a year after the W206’s debut, the German carmaker chose to retain the same name as the previous W205-based model, as opposed to the ‘C 53 4Matic’, as suggested in an earlier report.
Although the name remains unchanged, the new C43 4Matic has a more powerful engine than its predecessor. Below the bonnet, you’ll find a 2.0-liter turbocharged four-cylinder engine from the SL 43 replacing the previous 3.0-liter twin-turbo V6.
Despite the low power and number of cylinders, the downsized mill retains 408 PS (402 hp) and 500 Nm of torque, an improvement over the outgoing V6’s 367 PS (362 hp) and 520 Nm, saving for peak torque. It should be noted that these figures are higher than the 381 PS (375 hp) of the SL 43 at 6,750 rpm and 480 Nm.
Codenamed M139l (‘l’ refers to the longitudinal layout of the engine), the engine is said to be the world’s first series-production unit featuring a variant of the M139 used in the A45 hot hatch and featuring electric exhaust gas turbochargers, with technology derived directly from Formula 1.
According to the company, an electric motor about 4 cm thin is directly integrated between the turbine wheel in the turbocharger shaft and the compressor wheel on the intake side. It works to rotate the shaft at low revs until exhaust gases are absorbed, improving engine response from idle speed and across the entire engine speed range.
The motor is mated to a 48-volt light hybrid system that includes a belt-driven starter generator (RSG), which can provide an additional boost of 14 PS (13 hp) depending on the situation. Alternatively, it facilitates smooth operation of start-stop and gliding mode functions.
Like the SL 43, the new C43 comes with an AMG Speedshift MCT 9G nine-speed automatic gearbox, but unlike the convertible, it also gets an AMG Performance 4Matt all-wheel drive system with a rear biased torque distribution (31% front) and 69 % Back).
The C43 can be a sedan (W206) or a wagon (S206), the former takes 4.6 seconds to get from 0-100 km / h, whereas the wagon takes 4.7 seconds – one tenth faster than the W205 C 43. Both will hit speeds of up to 250 km / h, which can be increased up to 265 km / h with the optional AMG driver package. Another option is the AMG Real Performance Sound, which picks up the sound of the engine and takes it to the interior if the regular AMG exhaust system is not adequate.
The AMG Ride Control Suspension is ideal for the C43 model and features an aluminum front and rear double wishbone, coil springs and adaptive dampers. Includes an AMG Sports braking system with a rear-axle steering system with a maximum 2.5 degree steering angle. The latter features a 370 mm brake disc on the front with a four-piston fixed caliper and a 320-mm disc with a single-piston floating caliper on the rear.
Some of the system features of these vehicles can be configured via the AMG Dynamic Select system, which offers five drive modes (Slippery, Comfort, Sport, Sport + and Individual), including three modes (Basic, Advanced, Pro) with AMG Dynamics. For the car’s electronic stability program. The system of each vehicle can be configured individually based on the needs of the driver.
In terms of styling, the C43 boasts AMG-specific signals for identification from a regular C-class. In addition to the beaver brakes, the chrome features a panamericana grille with vertical struts and two round twin-tailpipe trim elements at the rear.
The sporty body kit you see here is similar to the AMG line package and has a rear apron like AMG front and rear bumper, matching side skirt and a diffuser. 18-inch AMG light-alloy wheels are the default, but buyers can also opt for 19- or 20-inch units.
Inside, you’ll find Artico man-made leather and upholstery AMG seats with red contrast topstitching and seat belts with microcut microfiber, along with genuine leather and nappa leather available at a price. The AMG performance steering wheel, silver colored aluminum shift pedals, carbon-fiber trim, AMG sports paddles as well as AMG-branded floor mats and illuminated door seal trims add a sporty look.
The MBUX infotainment system also features AMG-specific displays and functions, including shortcut buttons in AMG Dynamic Select Drive mode and AMG track pace drivers for those who want to log data at the end of the race track.
