About the Mercedes-Benz E450

Three versions of the E-Class have carried the E450 badge in the US. It replaced the E400 for 2019 with an uprated 3.0-liter twin-turbo V6, offered as a 4MATIC sedan and wagon and as a coupe and cabriolet with rear-wheel drive or 4MATIC.

With the 2021 update the V6 gave way to a 3.0-liter turbocharged inline-six with EQ Boost, an integrated starter-generator on a 48-volt system, while the 9G-TRONIC nine-speed stayed. The update also brought new front and rear styling, the MBUX system and a new steering wheel, and the wagon became the E450 All-Terrain.

For 2024 the E450 belongs to the new E-Class generation, offered as a 4MATIC sedan and All-Terrain wagon, with a more powerful mild-hybrid six, optional 4.5-degree rear-axle steering and an available AIRMATIC package. Mercedes-Benz quotes 0–60 mph in 4.4 seconds for the 2024 sedan, against 4.9 to 5.2 seconds for the 2019–2023 cars, all limited to 130 mph.

On a 2024 car, Stage 1 is calibrated for the car as it left the factory and takes it from 362 hp and 370 lb-ft to 430 hp and 470 lb-ft on pump-grade fuel. Stage 2 is calibrated for supporting bolt-on modifications and high-octane fuel, for 450 hp and 485 lb-ft. The gearbox has its own controller and torque limits, so the optional TCU tune raises them to match, with sharper shifts and stronger clutch clamping.

FAQ

E450 tuning questions

More answers in our FAQ

Which years of the E450 does this tune fit?

Our online catalog lists Stage 1 and Stage 2 tunes for 2019–2024 Mercedes-Benz E450 models. Choose your year at the top of the page; figures and prices for each year are shown in the table above.

How do I tell which E450 I have?

Go by model year. A 2019 or 2020 E450 has the twin-turbo V6. A 2021 to 2023 car has the inline-six with EQ Boost and the updated styling, with a reshaped trunk lid and taillights on the sedan. A 2024 sedan is the new generation, with flush door handles and a black panel joining the grille to the headlights.

Is the E450 related to the E53 AMG?

From 2021 both use a 3.0-liter inline-six with a 48-volt starter-generator, but the E53 adds an electric auxiliary compressor, the AMG SPEEDSHIFT TCT nine-speed and AMG Performance 4MATIC+ with variable torque distribution. It is covered on its own page, E53 AMG (W213).

What is the difference between Stage 1 and Stage 2 on the E450?

Stage 1 is calibrated for the car as it left the factory and runs on pump-grade fuel. Stage 2 pairs the calibration with supporting bolt-on modifications such as downpipes and runs on high-octane fuel. On a 2024 car, Stage 1 takes it from 362 hp to 430 hp. Stage 2 takes it to 450 hp.

Do I need a TCU tune for the E450?

A TCU tune is available as an add-on ($2,399). It raises the transmission’s torque limits and sharpens the shifts so the gearbox can handle the extra power. Ship your TCU in the same box as your ECU.
