Mercedes A45S / CLA45S AMG 2019+


This illusive Hot Hatch is something we have been working on for the last 2 years now, the first of these cars into the UK were the CLA Shape, same underpinnings, just a different shaped body.

We took delivery of the first CLA45S to private hands back in 2019 and with just 26 miles on the odometer, we set to work almost straight away to try and see how the new 45S AMG Platform would look for us Tuners, it was an incredible feat of engineering.

We worked on this model for a further 8-10 months of testing with various BETA testing cars owned by private individuals to receive feedback and real-world use reports so we could be sure our software for these cars was completely unparalleled as our W176 A45 Software had been.

You can find examples of A45Sā€™ Tuned by us featuring on well-known Automotive Channels on Youtube!

EST x Cobra Sport High Flow 200Cel Sports Cat Downpipe - With the introduction of additional sensors for temperature monitoring in the later W177 Models, it used to be an issue that hindered the ability to fit an “Off the Shelf” Downpipe to these cars. We are proud to offer The EST x Cobra Downpipe to the market which allows fitment to both Pre and Post-EGT Cars along with Software Calibration to suit this eventuality, this will only affect production cars made in 2021 onwards.
