One of the most powerful 4-Cylinder cars available

The new Mercedes CLA45 S is Affalterbach’s answer to the Audi RS3 Saloon.

The chairman of Mercedes-AMG, Tobias Moers, mentioned that AMG’s all-new 416hp car is currently the world’s most powerful 4-cylinder production car. It has one goal

“to raise vehicle dynamics and the sporty driving experience to a level previously unimaginable in the compact class”

The new M139 powerplant is loosely based off the M133 engine; the DOHC-head has been rotated 180 degrees, positioning the exhaust manifold towards the rear along with the BorgWarner twin-scroll turbocharger. Mercedes decided to make this change in order to lower the nose of the CLA for improved aerodynamics and improved cooling.

AMG certainly knows what they’re doing when it comes to designing powerful engines and it shouldn’t surprise you that the CLA45 S is brutally quick; the immense power from the M139 unit comes from just 2.0-litres, providing a specific output of 208.9 hp/L. and 500Nm of torque provided through an 8-speed dual-clutch transmission to all four wheels. Mercedes claims the CLA45 S will reach 100km/h in 4 seconds from standstill and will reach an electronically-limited top speed of 270km/h.

The CLA45 S also has a clever rear differential. The differential has a pair of clutches, one for each driveshaft. This allows the power to be distributed evenly between the two rear wheels; according to Mercedes, not only does this help with traction but it allows the introduction of “Drift Mode” allowing the CLA to retain a lairy attitude seen on previous AMG models if desired.

The standard equipment in the CLA45 S includes 19-inch alloy wheels over red brake callipers; on the tech-packed interior you’ll get an AMG branded steering wheel, a 64-colour customizable ambient lighting system, a 10.25-inch digital gauge cluster next to a 10.25-inch infotainment system. The seats are quite heavily bolstered but are unfortunately trimmed in artificial leather and suede, however Mercedes still knows how to make a good interior; the metal elements on the steering wheel and air vents adds a really nice visual touch, the foot-wells are lit up with a soft ambient light which is also a nice, luxurious touch. Overall the interior is kept simple yet is modern and sophisticated.
