Could debut in Frankfurt this September!
According to a leaked official Audi document, the upcoming SQ7 model will be powered by a 4.0-liter V8 TDI engine delivering 428 hp (320 KW).
No other details were leaked regarding the new Audi SQ7 but considering that the existing 4.2 liter TDI V8 engine delivers 626 lb-ft of torque (850 Nm), we expect the SQ7 to have at least 900 Nm of torque when hits the market.
With such power the luxury SUV will accelerate to 100 km/h in about 5.5 seconds and will reach a top speed of 300 km/h (186 mph).
From a technical point of view the SQ7 will become the German firm’s first model to come with electric turbos ( we don’t know yet how many ) – after the technology was featured on the 2014 Audi RS5 TDI-e concept.
Clearly, the main reason behind the electric turbo technology is the complete elimination of “turbo lag” effect – so expect a dramatic improve in terms of throttle response.
Looking at the technology that was presented on the RS5 TDI Diesel – the electric turbo is expected to boost efficiency up to 20 percent – and Audi says it requires only a quarter of a second to reach full boost.
“We’ve been in pre-development for more than ten years,” noted Steve McKinley, Honeywell Turbo Technology’s vice president of engineering. “It was a matter of waiting for that electric infrastructure to develop on the vehicles.”
Considering this – the SUV might come with two turbos – the electric one will reduce dramatically the lag while a second exhaust-driven turbo will be used for maximum power at wide-open throttle. Ideally both of them will be built into a single device.
Keep in mind that electric turbos require higher voltage to operate –in general 48 volt.
