Audi S5 Gains Mild Hybrid Tech For Slap In The Face Performance Scream

The Audi S5 now has a V6 diesel at its heart. Underpinned by mild hybrid technology, it equips the peak performer with impressive staying power between fill-ups and delivers even greater immediacy of response courtesy of an electric powered compressor. The V6 3.0 TDI engine, which will be introduced in both the S5 Coupé and the S5 Sportback in late 2019, now produces 347PS and delivers up to 700 Nm (516.3 lb-ft) of torque.

The 3.0 TDI in the S5 models is the most powerful version in the Audi V6 diesel engine line-up. Both the electric powered compressor (EPC) and mild hybrid (MHEV) systems are embedded in the standard 48-volt main electrical circuit.

For the first time in the S5 TDI, a powerful 48–volt belt alternator starter is the heart of the mild hybrid system with maximum recuperation power of up to 8 kW. A DC/DC converter steps this voltage down for components in the 12–volt electrical system.

A compact, air-cooled lithium-ion battery with a capacity of 0.5 kWh installed under the luggage compartment floor serves as the energy centre.

Acceleration to 62mph in the S5 Coupé takes 4.8 seconds and and 4.9 seconds in the S5 Sportback, with both reaching their peak at an electronically limited 155mph.
