There are 4WD, AWD, 4Matic, 4drive, and others, but what do these acronyms mean? They all essentially mean the same thing, namely all-wheel drive, but these types of powertrains are not all the same. Let's take a look at how they differ and how they perform!

This is a small sports car that can still provide driving excitement, somewhat as it did a few decades ago when turbocharged (gasoline) engines were not particularly progressive (or even tame) as they are today. They provided that kick in the back whenever you exceeded 2500-3000 rpm by fully depressing the accelerator pedal.

First of all, as we often do, let's take a look at what engine this Italian sports car is fitted with and what performance it has as standard. We are talking about the Levante 3000 V6 with all-wheel drive and an 8-speed automatic transmission. This sporty SUV has a mass of almost 22 quintals, and the engine has, as standard, a 350 hp power rating expressed at the speed of 5750 rpm,

Mercedes calls this new distribution management system Camtronic. The exact displacement is 2925cc, and this engine is available in two power levels; today we are talking about the most powerful one that delivers precisely 330 horsepower at the speed of 3600 - 4200 rpm with an exuberant driving torque of 700Nm available already at 1200 rpm and up to 3200 rpm without a dip in the torque curve.

If we talk about car engines, we are talking exclusively about 4-stroke engines. The engine torque value depends on the amount of gasoline that can be burned. Speaking of indirect gasoline injection engines (such as the 4-strokes mentioned above), these are constrained by the stoichiometric ratio, a value of 14.7 representing the ratio (by weight, not by volume) between the mass of air and the mass of gasoline.
