The A45 AMG may be the baby of the AMG lineup but the tuning company, Posaidon, managed to pull out a whopping 445 horsepower and 535 nm of torque from it. Yes, 445 horsepower and 535 nm of torque from a 4-cylander in a car that weighs just over 3,400 pounds. As is, AMG’s 2.0 liter four-cylinder turbocharged engine is considered among the best in the world of its kind, outputting 360 hp – numbers you would normally see from a V8.
If your jaw hit the floor and that’s too much power for you, Posaidon offers toned down versions. The first kit, offers a minor power bump- 385 hp and 485 Nm (357 lb-ft) of torque. Kit two is a slightly more beefed up – 405 hp and 490 Nm (361 lb-ft) of torque. But let’s all be honest, the more power the better making the third and final kit the real winner – 445 hp kit with 535 Nm of torque (394 lb-ft).
