Sporty, powerful, and efficient: Audi presents the new generation of the SQ5 TDI

  • Three-litre V6 diesel engine generating 341 HP (251 kW) and 700 Nm
  • Introduction of Mild Hybrid Technology
  • Powerfully rugged exterior design with striking sporty elements

Ingolstadt, November 12, 2020 – Even sharper, sportier, and more efficient: The optimised Audi SQ5 TDI** now looks even more impressive. Its V6 three-litre diesel engine with an output of 341 HP (251 kW). The sharper design underlines the sporty character of the sport SUV. Rear lights featuring the new digital OLED technology are available as an option for the top Q5 model.

The SQ5 TDI** has a successful track record. Its first generation, which was launched in the autumn of 2012, already marked the starting point for a success story – as the first Audi S model powered by a diesel engine.

The three-litre V6 boasts an output of 341 HP (251 kW) and 700 Nm of torque**. The wide engine speed range can be used continuously between 1,750 rpm and 3,250 rpm. The 3.0 TDI** develops its power earlier and more forcefully than before. It accelerates the top model of the Q5 product line** from 0 to 100 km/h in 5.1 seconds and on to an electronically limited top speed of 250 km/h. An actuator in the exhaust system, as fitted to the first SQ5 TDI**, gives the V6 a sonorous sound.


Three-litre TDI with extensive innovations – now even more powerful and efficient

Many details of the V6 3.0 TDI** have been revised. The pistons are no longer made of aluminum but of forged steel– the new material reduces heat losses. Due to the higher strength, they do not incur a weight penalty compared with the aluminum pistons. A stepped recess in the piston makes combustion faster and more efficient. The solenoid injectors used to inject the fuel operate with consistently high precision thanks to a new piezo sensor that monitors the closing of the needle. They can perform up to eight injections per work cycle, with injection quantities that are scalable with even greater precision. The maximum injection pressure is 2,500 bar.

The intercooler has been changed over from an air/air cooler in the bumper to an indirect water/air cooler in the inside V of the engine. The shortened intake air paths help to build up boost pressure quickly. The indirect intercooler is more effective and can even heat the intake air shortly after the engine is started in cold ambient conditions in order to reach the ideal combustion temperatures more quickly. This offers the advantage since exhaust gas cleaning responds more quickly. The turbocharger now features a smaller and lighter compressor wheel that gets into gear with exceptional speed – a key factor in the engine’s spontaneous and high torque build-up. The exhaust manifold benefits from improved insulation. Thanks to this measure, the exhaust gas reaches the optimum temperature more quickly after a cold start.


MHEV and EPC: even greater efficiency and spontaneity

The 3.0 TDI** brings two technologies that reduce consumption and improve the engine response. The 48-volt mild hybrid system (MHEV) integrates a belt alternator starter (BAS), a lithium-ion battery that provides buffer storage, and a 48/12-volt voltage converter. When the car decelerates, the MHEV system recovers up to 8 kW of power. The sport SUV** can coast for up to 40 seconds with the engine switched off – after which time the powerful BAS conveniently restarts the engine. The MHEV system has the potential to reduce customer fuel consumption by up to 0.7 litres per 100 kilometres.

The second technology component is the electric powered compressor (EPC), which helps out whenever the exhaust gas flow provides too little energy to drive the turbocharger. A compact electric motor, which also uses the compact 48-volt system, accelerates the compressor wheel of the EPC to 65,000 rpm in roughly 300 milliseconds. The EPC is now used more frequently and across a broader engine map. It supports a more spontaneous engine response when the vehicle moves off as well as when accelerating from low engine speeds.


Shifting gear quickly and conveniently: the eight-speed tiptronic

Power is transmitted by an eight-speed tiptronic featuring fast and convenient shifting and a gearshift strategy that has been adapted to suit the modified engine. When the SQ5 TDI** is in coasting mode with the engine switched off, a clutch in the central transmission opens and interrupts the power flow.

In normal driving conditions, the quattro permanent all-wheel drive system distributes torque between the front and rear axle in a 40:60 ratio. In the event of slip, most of the drive torque goes to the axle with the better traction. Up to 70 percent can flow to the front wheels and a maximum of 85 percent to the rear wheels. During fast cornering, the wheel-selective torque control rounds off the handling with minor brake interventions at the relieved wheels on the inside of the curve.


Supreme precision: the suspension

The suspension of the Audi SQ5 TDI** is fully equipped to handle the performance of the powerful diesel drive. Five-link suspensions guide each of the four wheels. The S sport suspension with damper control lowers the body by 30 mm (1.2 in) compared with the Q5** and impresses with an exceptionally wide spread between comfort and dynamism.

Together with the optional sport differential, engine, steering and tiptronic, the controlled dampers are integrated into the Audi drive select dynamic handling system fitted as standard. The driver can use it to control the character of these systems in six profiles: auto, comfort, efficiency, dynamic, offroad, and individual. A seventh profile, allroad, is added if the optional adaptive air suspension with S-specific tuning is specified – this air suspension adjusts the ride height of the body through five levels depending on the driving situation.

The updated Audi SQ5 TDI** is fitted with 20-inch aluminum wheels with tyres in the size 255/45 as standard.


New accents: the exterior design

The modified Audi SQ5 TDI** has a powerful stance, with striking details that give it an even more rugged appearance. Vertical fins provide structure to the large side air inlets on the front bumpers. In the octagonal Singleframe grille that is specific to the S models, large octagonal honeycomb sections are linked by narrow bars. These have an aluminum finish, as do the fins on the air inlets.

Audi includes LED headlights as standard and offers Matrix LED headlights with automatic high beam and dynamic turn signals as an option. At the rear, a matte aluminum strip is integrated in the lower bumpers, below which are the diffuser insert and four chromium-plated oval tailpipe trims.


Sporty black and grey: the interior

The SQ5 TDI** features a black or dark grey interior with illuminated aluminum door sill trims bearing S logos. The electrically adjustable sport seats featuring embossed S logos are available in a choice of three upholstery variants. A leather/ synthetic leather combination is offered as standard while a material mix of leather and Dinamica with S embossing is available as an option. The new Dinamica microfibre material consists mainly of recycled plastic and replaces Alcantara. Standard you have Fine Nappa leather with a rhombus pattern in magma red.

The luggage compartment has a basic capacity of 520 litres (18.4 cu ft), increasing to 1,520 litres with the rear seat backs folded down. The electrically operated tailgate, a stainless steel loading sill protector as well as aluminum roof rails are fitted as standard. The sport SUV can pull trailers weighing up to 2.4 metric tons (braked, on a 12 percent incline).


Operating system, infotainment and Audi connect

The MMI touch display with a 10.1-inch diagonal, a central element of the MIB 3 modular infotainment platform, serves as a combined input and display device in the centre of the instrument panel. A natural language voice control system and the multifunction steering wheel are available as additional control levels. The 12.3-inch display provides three different graphic layouts: Dynamic, Sport and Classic. Audi offers a head-up display as a further option.

If several drivers use the car, they can store their personal settings in up to six individual profiles.


Convenient and precise: the driver assist systems

The SQ5** incorporates all of the assistance systems from the Q5**. The turn assist, collision avoidance assist, and exit warning help improve safety. The adaptive cruise assist can take over accelerating, decelerating and keeping in lane for drivers over long distances. The predictive efficiency assist helps them maintain a predictive driving style with the goal of lowering fuel consumption.

The updated Audi SQ5 TDI** will be built at the Mexican plant in San José Chiapa and is due to arrive in Ireland in Spring 2021.
