A reportedly official spec-sheet of the upcoming 2015 Audi SQ7 has leaked online. It reveals that the car will pump out a total of 428 hp (320 kW) when it reaches the market.
While no torque details are known, it has previously been confirmed that the SQ7 will make use of a 4.0-litre TDI V8 engine. Due to the fact that the German marque’s existing 4.2-litre TDI V8 delivers a total of 626 lb-ft of torque, a figure around there can be expected for the new SQ7.
Arguably the most important aspect of the SQ7’s engine will be the fact that it will utilise electric turbochargers. Consequently, the new Audi SQ7 will become the German firm’s first production model to use electric turbos and will follow on from the 2014 Audi RS5 TDI-e concept which debuted the technology.
The entire premise behind electric turbochargers is that they completely eliminate lag to dramatically improve throttle response. This is achieved through the use of an electric motor which spins up the turbo before the hot exhaust gases are funnelled into it. This basically means the turbo is always spooled up.
Given the fact that prototypes of the Audi SQ7 have been spied testing with camouflage, we expect to see the model debuting at the IAA Frankfurt Motor Show 2015 next month.
