A biturbo petrol engine replaces the 6-cylinder diesel and brings a truly sporty sound.
The Audi SQ7 and Audi SQ8 crossovers of the new model year will be equipped with the 4.0-liter petrol engine. The biturbo V8 is a new development with up to 507 hp and peak 770 Nm of torque, Audi reports in a press release.
The sprint from zero to 100 km/h takes just 4.1 seconds. The maximum speed is limited to 250 km/h. The fuel consumption is around 12 l/100 km (combined).
The petrol TFSI will replace the diesel-six. The outgoing engine is 70 hp less powerful, but produces more torque. In addition, instead of a 48-volt mild hybrid system, the 8-cylinder petrol engine uses an automatic half-cylinder shutdown function at reduced load. This technology also helps reducing fuel consumption.
Audi explains that in the exhaust system, two actuators modulate the eight-cylinder sound. The coils in the active engine mounts minimize the transmission of vibrations to the housing by creating antiphase vibrations. They block engine vibrations and largely eliminate them.
Audi claims, according to Autocar, that the new mill gives a “classic V8 soundtrack”.
Audi’s 8-cylinder TFSI flagships of the SUV range will hit European markets this autumn. In Germany, for example, such an SQ7 will cost from 93,000, the SQ8 – from 101,000 euros.
