• 3.0 V6 TDI engine with 255kW, 700Nm, electric powered compressor, classic turbocharger and 48V mild-hybrid technology
• Eight-speed tiptronic and quattro permanent all-wheel drive
• Suspension with damper control and air suspension available

The 3.0 V6 TDI engine in the new Audi SQ5 TDI combines instant power with high efficiency. Producing 255kW and 700Nm, its massive torque is available continuously across a broad range from 2500 to 3100rpm. The V6 diesel provides acceleration from standstill to 100km/h in 5.1 seconds, on its way to an electrically limited top speed of 250km/h. In the NEDC, it consumes between 6.6 – 6.8 litres of diesel per 100 kilometres, corresponding to 172 – 177 grams of CO2 per kilometre.

Audi has systematically refined the drive concept from the full-size SQ7 TDI for the new SQ5 TDI. The 48-volt main electrical system includes an electric powered compressor (EPC) and a mild hybrid system. Energy is stored in a compact lithium-ion battery with an electrical capacity of 10Ah located beneath the luggage compartment floor. An AC/DC converter connects the conventional 12-volt electrical system.

New assistant for the turbocharger: the EPC
The electric powered compressor is the ideal assistant for the turbocharger. It helps out whenever the exhaust gas flow provides too little energy to drive the turbocharger, i.e. when starting off and accelerating in the low-rev range up to 1650 rpm. High torque is available immediately with no turbo lag, whether starting off, passing or exiting a curve. In everyday driving situations, the early and rapid torque development made possible by the technology keeps revs and fuel consumption low.

The electric powered compressor is located in the intake air path downstream of the intercooler and close to the engine. If the load demand from the accelerator is high but there is still too little boost from the turbocharger, the EPC comes into play. A compact electric motor with an output of 7kW accelerates the compressor wheel to 65,000 rpm in 300 milliseconds, producing a relative boost pressure of 1.4 bar.

Recuperation, coasting and smooth starts: MHEV technology
The MHEV system (mild hybrid electric vehicle) in the new Audi SQ5 TDI can reduce real-world fuel consumption by as much as 0.7 litres per 100 kilometres. At its core is a belt alternator-starter (BAS) connected to the crankshaft. During deceleration, it can recuperate up to 12kW of energy, with the electrical energy stored in the lithium-ion battery, from where it is dynamically distributed to the consumers in the electrical system.

If the driver lifts off the accelerator at a speed between 55 and 160km/h, the new Audi SQ5 TDI can, depending on Audi drive select setting and driving situation, either recuperate, roll at idle with the clutch disengaged or coast with the engine off for up to 40 seconds, with the BAS smoothly restarting the engine the next time the accelerator is depressed. MHEV technology allows for start/stop operation at a speed of up to 22km/h and if the vehicle is equipped with the adaptive cruise control (ACC), the engine restarts while the brake pedal is still depressed as soon as the vehicle in front of the SQ5 TDI begins to move.

Optimised for supreme pulling power and maximum efficiency: the engine
This top output version of the 3.0 V6 TDI engine has been further developed and modified in numerous areas, with the crankshaft, pistons, connecting rods and oil management all specially configured for the more stringent demands. The thermal management system is highly versatile, the crankcase and the cylinder heads having their own cooling circuits which allows the engine oil to warm up quickly after a cold start. The coolant flow is directed to the oil cooler, the EPC, the BAS and the turbocharger as needed. A large exhaust gas turbocharger with variable turbine geometry (VTG) produces a relative boost pressure of up to 2.4 bar, while a sound actuator in the exhaust system gives the TDI a sonorous sound.

Fast, smooth and efficient: the eight-speed tiptronic
A fast and smooth-shifting eight-speed tiptronic handles the power transmission. Its lower gears feature short, sporty ratios, while the upper gears are long to reduce revs and fuel consumption, while new detailed solutions enable the tiptronic to work effectively with MHEV technology. If the sport SUV is rolling and the engine is idling or shut off, a clutch in the central transmission opens and interrupts the power connection. An electric oil pump enables the tiptronic to engage the gear while coasting that will be needed at restart.

quattro and sport differential
Like every S model from Audi, the new SQ5 TDI comes standard with quattro permanent all - wheel drive. In normal driving conditions, its self-locking centre differential distributes torque between the front and rear axle in a 40:60 ratio. When slip is detected, the majority of the power is directed to the axle with the better traction. Depending on the driving situation, a maximum of 70 percent can flow to the front or 85 percent to the rear.

Wheel - selective torque control, an intelligent software function complementing the quattro drive, is active on all surfaces. During dynamic cornering, it brakes the wheels on the inside of the curve minimally before they begin to slip. The power is thus directed via the differential to the wheel with the better traction. The sports SUV turns into the curve ever so slightly, its self-steering remaining neutral to ensure handling remains stable, precise and agile.

Customers can also order the SQ5 TDI with a sport differential on the rear axle. It actively distributes the power between the rear wheels during dynamic cornering. The sport differential literally pushes the car into the curve, to negate understeer while more torque is sent to the outside rear wheel when accelerating out of tight radii to further improve agility.

Sporty and precise: the chassis of the new SQ5 TDI
Sophisticated five-link suspension at the front and rear lays the foundation for the sporty driving characteristics of the new Audi SQ5 TDI. Audi also offers optional dynamic steering, which uses strain wave gearing to vary the steering ratio over a very wide range as a function of speed and steering angle. The suspension with damper control comes standard in the new SQ5 TDI, lowering the body by 30 millimetres compared with the Q5 with standard suspension. It also offers a particularly wide spread between comfort and dynamics.

Along with the sport differential, engine, steering and tiptronic, the dampers are integrated into the Audi drive select dynamic handling system. With Audi drive select, the driver can vary the function of these systems via multiple profiles. Audi also offers the S-specific adaptive air suspension as another option. This adapts not just the damping but also the body's trim to the respective driving situation.
