One of them is an "electric auxiliary compressor" (eZV, a German acronym), which can spool up to 70,000 RPM in just 300 milliseconds.This helps negate the lag of the larger, exhaust-driven turbo. And as turbocharging becomes more effective and efficient, six-cylinders are gradually replacing V8s. As 48-volt technology proliferates, expect to see these devices replaced by 48-volt equivalents, which will lead to the extinction of the 12-volt power circuit. Particulate traps have long been a necessity for diesel engines to … The Mercedes M256 I6 hybrid wins the innovation award for the most advanced combination of technologies.

Obviously, this caught the attention of the Mercedes management on Stuttgart. To explain, we need to get nerdy. 3. But that decision created an inherently flawed design. Luckily for us, Mercedes-Benz got it right with the W211 E-Class. Road & Track participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our links to retailer sites. With these two quick responses, there’s no need to fit a tiny turbocharger to minimize turbo lag. While it was an excellent feature added to some Mercedes-Benz models, but it was also prone to failure. The M156 is the first automobile V8 engine designed autonomously by Mercedes-Benz subsidiary Mercedes-AMG, as previous AMG engines have always been based on original Mercedes engines.The engine was designed to be a naturally aspirated racing unit, and is also used in a number of high-performance AMG-badged Mercedes-Benz models.
