Specialists of the tuning studio RENNtech, founded in 1989 by Hartmut Fuichl, an AMG native, prepared a tuning kit for the Mercedes-AMG A45 4MATIC and A45 S 4MATIC + based on the W177 series. The main attention of the motorists was given to the two-liter “turbo four” M139, the power of which, depending on the degree of forcing, will be 475, 550 or 600 hp.
At the moment, the basic tuning kit is being tested, which increases the power of the unit from 421 to 475 hp, and the maximum torque is from 500 to 575 Nm. On sale such a kit will appear in the second half of January. Packages that increase the return of the unit to 550 and 600 hp, the tuner promises to release before the end of the first quarter. How the pumping of the motor will affect the dynamic characteristics is not specified. The factory-set A45 S hot hatch accelerates from standstill to 100 km / h in 3.9 seconds. It is expected that the installation of a tuning kit will improve the result by several tenths of a second.
RENNtech is also preparing several other parts for the A45. By the end of February, owners of the Mercedes-AMG A45 will be able to order additional exhaust and a sports catalytic converter. Also in development is a new upgraded exhaust system that improves the sound of the car, but retains the original catalytic converter. As an option, the tuner offers to install an exhaust valve module with remote control, which will provide a “formidable roar” of the motor, regardless of driving mode.
To refresh the appearance of “charged” hot hatch offers by installing 19- or 20-inch alloy or forged custom wheels RENNtech VOSSEN. Also for high-performance “five-door” you can order a set of sports lowered springs.
