As we previously anticipated, Mercedes is going to install the new 2.0 liter 381 hp engine of the facelifted A45 AMG on all models bearing the AMG lettering and built on the front wheel drive platform.
This means the CLA45 AMG, the CLA45 AMG Shooting Brake and the GLA45 AMG will benefit from the new engine, and also from comprehensive updates to transmission, suspension, electronics and equipment. the CLA 45 4MATIC now accelerates from zero to 100 km/h in 4.2 seconds, which is 0.4 seconds faster than its predecessors (Shooting Brake: 4.3 seconds, GLA: 4.4 seconds).
At the same time it has been possible to retain the textbook consumption level on a par with the previous models: even the fuel consumption figures of the CLA 45 4MATIC and CLA 45 4MATIC Shooting Brake, from 6.9 litres per 100 kilometres (corresponding to 161 g/km CO2) is very low. The GLA 45 4MATIC consumes 7.4 l/100 km (corresponding to 172 g/km CO2).
The engine, transmission and steering characteristics of the Mercedes-AMG compact models can be changed via rotary switch with the new, standard-fit AMG DYNAMIC SELECT transmission modes. There is a choice of  four modes, namely "Comfort“, "Sport", "Sport+" and "Individual" or "Race" (in conjunction with AMG RIDE CONTROL sports suspension).
The standard-fit AMG SPEEDSHIFT DCT 7-speed sports transmission has now shorter transmission ratios in 3rd to 7th gear. Also as standard, the new AMG compact sports cars transfer the driving power to all four wheels for optimum traction and maximum driving pleasure. The torque distribution of the AMG Performance 4MATIC system ranges from 100 percent front-wheel drive through to a 50:50 split between the front and rear axles.
A multiple-disc clutch integrated into the rear axle differential redirects the engine torque to the rear wheels as required within fractions of a second.
The CLA 45 4MATIC costs €56,673.75, the CLA 45 4MATIC Shooting Brake €57,268 and the GLA 45 4MATIC €56,168.
