This cools the incoming air, even more, making it denser and preventing detonation. It’s why the 1994 ST205 Toyota Celica GT4 is so widely-regarded for having one at that time. It’s often fitted to rally cars, but it’s only recently that high-end performance cars have started coming with it from the factory. To avoid this, in addition to intercoolers, sometimes turbocharged engines will come with water injection.

However, not only does that put more stress on the internal components, but it also increases the change of premature ignition. One simple way for a previously-turbocharged engine to make more power is to crank up the boost settings. It’s up against a good one.Also, there’s the matter of the boost process itself. Now, our focus turns to Jaguar Land Rover, which recently announced a similar motor for its cars. Mercedes had high expectations to meet in its return to straight sixes, and the M256 blows right past them. The M256 in AMG guise is a remarkable piece of engineering. My only real gripes with the M256 is that it doesn’t rev as freely nor sound as good as BMW’s B58 3.0-liter straight-six, but those are minor. That included a few attempts at stretching the E53’s legs.

According to the car’s trip computer, I averaged 26.4 mpg on a 30-mile trip at an average speed of 37 mph. The EPA quotes the E53 Coupe as having a 28-mpg highway fuel-economy rating, and that’s entirely believable. The ISG allows the E53’s engine to shut off entirely for brief periods, but as soon as you touch the throttle, it springs back into life, exactly in the right gear at the right RPM. Some Mercedes products will decouple the engine from the transmission during coasting, allowing it to sit at idle, using less fuel. On the highway, you might get good fuel economy if you put the E53 in Eco mode. Really, this is more of a comfortable GT car than anything else. Out on the highway, the E53’s power is ample, with effortless passing afforded by all its torque-boosting accoutrements. Blame a 4519-pound curb weight, as measured by our colleagues at Car and Driver. You're just left with the sensation that the E53’s engine is a lot bigger than 3.0 liters.īut it doesn't feel downright quick in the way you’d expect from a car with an AMG badge. The switch between the various power-adding appendages happens seamlessly. In fact, it’s hard to suss out what the engine is doing at any given moment. It won’t help you figure out what’s generating the boost though, as it seems to switch between showing levels from the ISG, electric compressor, and turbocharger.

The E53’s digital gauge cluster can display a boost gauge, and it’s a lot of fun to watch it go from zero to full in an instant. The ISG muscles the car along with authority at low revs, while the combination of the electric compressor and exhaust-driven turbo take care of everything beyond with no perceptible lag. Mercedes says there’s a maximum of 384 lb-ft, which is available from 1800 to 5800 rpm, but it feels like it has more.
