At the forefront of the range is the Audi SQ5 Sportback TDI. Its cultivated three-liter diesel engine produces an output of 251 kW (341 PS), the powerful torque of 700 Nm (516.3 lb-ft) is constantly available from 1,750 rpm to 3,250 rpm. An actuator in the exhaust system lends the sound tone and richness. Performance: 0 to 100 km/h (62.1 mph) in 5.1 seconds, top speed of 250 km/h (155.3 mph) (electronically limited).
The 3.0 TDI has been made even better in many details. The pistons have been changed from aluminum to forged steel. This new material reduces heat losses and because of its strength does not incur any weight penalty compared with aluminum pistons The solenoid valve injectors are able to inject the fuel with a constantly high level of precision because a new piezoelectric sensor monitors the closing of the needle. It can perform up to eight individual injections per work cycle and also meter minimal fuel quantities with high precision.
A small, light compressor wheel rotates in the turbocharger of the V6 diesel engine, getting up to speed especially quickly – an important factor for the spontaneous and powerful development of torque. The intercooler now runs via a new, indirect water-air cooler in the inside V of the engine. The quick build-up of the boost pressure benefits from the short intake air routes.
