Taking on the M178.
The automotive industry is shifting towards downsizing engines and adding in turbochargers to get more power with greater efficiency. The same is the case for Mercedes-Benz’s high-performance AMG division that has downsized its naturally-aspirated 6.2-liter V-8 to the new M178 4.0-liter, twin-turbocharged V-8.
PP-Performance is one of the aftermarket companies that’s taking advantage of the new force-fed nature of the newest batch of Mercedes-AMG engines, starting with the new C63 S and GT S models. While both cars feature a slightly different version of the M178 V-8 engine, they’re both very similar and PP-Performance developed performance upgrades to take them to the next level.
Starting things off is the Mercedes-AMG C63 S with its factory 510 horsepower output. PP-Performance created a full software tuning program that pushes the engine to 613 horsepower and 567 lb-ft. of torque. That’s good enough to send the C63 S to 62 mph from rest in only 3.59 seconds as opposed to the factory 4.0-second time. Top speed is also pushed back to 190 mph.
The Mercedes-AMG GT S also received a similar software tune that equates to a total of 610 horsepower and 564 lb-ft. of torque with a higher 201 mph top speed. Acceleration also improves to 3.4 seconds to 62 mph as opposed to the factory 3.8-second time.
For both cars, customers that desire even more power can opt for the PP-Performance racing filter, cat-less exhaust kit, and software integration for an additional 33 horsepower.
Both of the PP-Performance software tunes for the Mercedes-AMG GT S and C63 S are available for 2,899 euros. The optional racing filter is available for 199 euros while the exhaust upgrade is priced at 2,499 euros.
