Audi will put its electric turbocharging system into production on a high performance version of the Q7 which will be christened SQ7. The new Q7 might hit the international market by 2015 and this new technology equipped SQ7 will follow its launch.
Currently, the electric turbocharger is used in two concept vehicles the A6 TDI concept which makes 322bhp and the RS5 TDI-e which has a rated output of 380bhp.
Audi's board member for technical development, Ulrich Hackenberg, told a publication, “The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016.”
Diesel engines have the most turbo lag at low engine speeds, this is where the electric charger comes into play by reaching maximum boost in just 250 milliseconds for instant throttle response. The electric charger is bypassed once high enough exhaust pressure is detected that’s when the conventional turbo kicks in.
We can expect the new Q7 to reach the Indian market within a year of its global launch and we are hopeful that Audi introduces the SQ7 here.
