In the previous model, some of the gasoline engines were mounted with a forward tilt of 10 degrees, and their exhaust side faced the radiator grille, while the exhaust side of the TDI engine faced the bulkhead. The turbocharger was redesigned for the use of low-pressure exhaust gas recirculation. liters of fuel per 100 km (57.4

The idea is to take as little energy as possible from the internal combustion engine. We therefore electrically powered several of the vehicle’s auxiliary items of equipment such as the air-conditioning, water pump, fuel pump and the steering pump. Aerodynamics: the water drop effect. and distributes it in real time.

The Audi valvelift system, which adjusts the lift of the valves in two stages, is active on the exhaust side. The new rotating core module can set the water temperature between 85 and 107 °C as a function of load and rpm to always achieve the best compromise between minimal internal friction and thermodynamic efficiency.

Second-generation 3.0L V6 Diesel for Audi Q7 Cuts Fuel Consumption 19%; Lower-Emission Variant Meets Euro 6 or US Regs

Green Car Congress

This V6 diesel accelerates the Q7 from a standstill to 100 km/h (62 mph) in 7.9 seconds and reaches its top speed at 215 km/h (134 mph) or, with adaptive air suspension, 218 km/h (135 mph). A new chain-driven timing gear and a complex cylinder wall machining process have reduced internal friction. The latest 3.0
