Audi praises the Diesel engine!

While electrification and hybridization dominate the market, Audi shows that diesel can still be reinvented.

In a context where the automotive industry emphasizes 100% electric and advanced hybridization, Audi surprises by updating its diesel engine for the Audi A6. The German manufacturer presents a 3-liter V6 TDI with 220 kW (299 hp) and 580 Nm of torque, enhanced by MHEV plus technology and an electric compressor, demonstrating that diesel is not just an outdated solution.

This development illustrates diesel’s ability to meet the expectations of a broad audience while becoming more environmentally friendly. The MHEV plus partial electrification combines three components: a belt starter-generator, a powertrain generator, and a lithium phosphate battery. This system provides up to 18 kW (24 hp) of additional power, improves low-end torque, and enables significant energy recovery during deceleration phases, while reducing consumption and emissions.

Audi advocates for a certain open-mindedness

The electric compressor represents another major innovation. It assists the conventional turbocharger in a two-stage supercharging system, eliminating turbo lag and providing immediate throttle response. Coupled with the powertrain generator, it ensures powerful starts and overtakes, while optimizing energy efficiency. Audi therefore claims to have an engine capable of linear and impressive acceleration, reminiscent in some ways of the driving feel of an electric motorization.

Audi complements the package with the sustainable fuel HVO 100, derived from vegetable oils or industrial residues, capable of reducing CO₂ emissions by 70 to 95% compared to traditional diesel. This compatibility reinforces the role of diesel as a more responsible alternative, even within a global strategy geared towards electrification.
