2019 Audi SQ2 – Video
Striking design meets tremendously fun driving: Audi is presenting the SQ2 for the first time, the new top model of the Q2 family stands out in the compact SUV segment: It puts out 221 kW (300 hp), enough to sprint from 0 to 100 km/h (62.1 mph) in 4.8 seconds and a top speed of 250 km/h (155.3 mph). quattro all-wheel drive and the S sport suspension applies the power smoothly to the road. The Audi SQ2 is also at the head of its class with respect to operation, infotainment and assist systems.
0 – 100 km/h (62.1 mph) in 4.8 seconds: the engine
The heart of any Audi S model is the engine, and the 2.0 TFSI in the SQ2 (combined fuel consumption in l/100 km: 7.2 – 7.0*; combined CO2 emissions in g/km: 163 – 159*) is in peak form. It puts out 221 kW (300 hp) and a constant 400 Nm (295.0 lb-ft) of torque between 2,000 and 5,200 rpm. Developed by Audi engineers and built in Győr, the engine outclasses all its rivals in this segment. The same applies to the sport SUV’s performance: The sprint from 0 to 100 km/h (62.1 mph) takes 4.8 seconds, and top speed is a governed 250 km/h (155.3 mph).
The four-cylinder TFSI in the Audi SQ2 is a high-performance, 1,984 cc engine. It responds instantly up to the redline at 6,500 rpm. In the dynamic mode of the Audi drive select dynamic handling system, it responds even more directly, with brief double-clutching accompanying the gear changes by the S tronic. The engine develops a particularly sonorous sound when driven dynamically. The 2.0 liter TFSI engine weighs only around 150 kilograms (330.7 lb), which benefits not just the total weight of the Audi SQ2, but also the axle load distribution.
Numerous high-tech features hone the profile of the powerful four-cylinder. The intake and exhaust camshafts are adjustable to optimize fill and gas exchange. On the exhaust side, the Audi valvelift system (AVS) adjusts valve lift in two stages based on demand. This reduces flushing losses in the combustion chamber and ensures optimal flow of exhaust gas to the turbocharger, particularly in the low rpm range. The advantages of this are agile engine response and a further increase of torque. Controlled by a fast and precise electric overflow valve, the turbocharger develops its maximum boost of 1.4 bar (relative) very dynamically. This engine management system enhances efficiency and reduces fuel consumption during operation under part load.
Efficiency is also a major focal point with the 2.0 TFSI. Two electric-powered rotary valves consolidated into a module regulate the coolant flows. Another major component of the thermal management system is the exhaust manifold integrated into the cylinder head. It helps the engine to warm up quickly.
Targeted measures implemented in many components increase strength and reduce internal friction. The regulated oil pump requires little drive energy. Under part load, the engine management system deactivates FSI gasoline direct injection. Instead, fuel is injected indirectly into the intake manifold, which reduces particle emissions. A particle filter also cleans the exhaust gas.
