AUDI HAS ANNOUNCED changes to the engines in some of its models, offering more efficiency and greater choice for buyers.
For the first time in the current generation, the new Q7 range will be joined by a petrol model, with the 55 TFSI model set for arrival in the first quarter of 2021.
With a 250kW and 500Nm 3.0-litre TFSI engine under the bonnet, the Q7 55 TFSI will offer a similar level of prodigious performance to that of its diesel siblings. It reaches 100 km/h from rest in 5.9 secs, making it the fastest Q7 model in the range (excluding SQ7).
The 55 TFSI engine is a 90-degree V6, with the exhaust located inside the vee. The short gas paths and the twin-scroll turbocharger, which prevents unfavourable interactions between the gas columns, guarantee spontaneous throttle response.
Audi developed the B-cycle combustion process specially for the partial-load range. It increases the efficiency of the 3.0 TFSI by means of special valve timing. To support it, the Audi valve-lift system adjusts the intake valves in two stages based on load and engine speed. In the 3.0 TFSI, the coolant also circulates in separate circuits for the crankcase and the cylinder head. The exhaust manifolds are integrated into the cylinder heads; this helps the engine heat up quickly after a cold start.
Performance has always been a highlight of the Audi TT, and the 2021 TT Coupe 45 TFSI quattro becomes the most powerful and the fastest TT model in the brand’s history (excluding TTS/TT RS).
With a step-up in power to 180kW/370Nm, the TT also benefits from a new, slick-shifting 7-speed S tronic dual-clutch transmission. The combination seamlessly delivers the kind of brisk acceleration expected of the TT sports coupe, reaching 100 km/h in just 5.2 secs.
Similarly, the A4 allroad quattro 40 TDI is endowed with an additional 10kW, for a peak output of 150kW and 400Nm of torque, thanks to its powerful 2.0-litre, four-cylinder engine. The 0-100km/h sprint is dispatched in 7.3 seconds, half a second faster than its predecessor.
Not only powerful, the new 12V MHEV engine is equipped with twin-dosing Selective Catalytic Reduction (SCR), with double AdBlue injection. Audi uses complex exhaust aftertreatment systems to meet increasingly lower emission limits, and such technologies reduce the nitrogen oxide emissions of TDI engines by more than 90 percent. The A4 allroad 40 TDI is also one of the most fuel-efficient wagons in the Australian market, with fuel consumption a meagre 4.9L/100km.
The Audi TT 45 TFSI is available in showrooms now, with the Audi Q7 55 TFSI and Audi A4 allroad quattro 40 TDI arriving in early 2021.
