combined CO2 emissions in g/km*: 185-185(297.7-297.7g/mi)) now looks even more impressive. Its V6 three-liter diesel engine with an output of 251 kW (341 PS) delivers its power smoothly and forcefully. 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 (combined fuel consumption in l/100 km*: 7.0-7.0(33.6-33.6US mpg); combined

CO2 emissions in g/km*: 185-185(297.7-297.7g/mi)) has a successful track record. Its first generation, which was launched in the fall of 2012, already marked the starting point for a success story - as the first Audi S model powered by a diesel engine.

In its latest extended version, the three-liter V6 boasts an output of 251 kW (341 PS) and 700 Nm (516.3 lb-ft) 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 (combined fuel consumption in l/100 km*: 7.0-7.0(33.6-33.6US mpg); combined CO2 emissions in g/km*: 185-185(297.7-

297.7 g/mi)) from 0 to 100 km/h (0 to 62.1 mph) in 5.1 seconds and on to an electronically limited top speed of 250 km/h (155.3 mph). An actuator in the exhaust system, as fitted to the first SQ5 TDI**, gives the V6 a sonorous sound.

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

Many details of the V6 3.0 TDI (combined fuel consumption in l/100 km*: 7.0-7.0(33.6-

33.6 US mpg); combined CO2 emissions in g/km*: 185-185(297.7-297.7g/mi)) 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 liters (0.2 US gal) per 100 kilometers (62.1 mi).

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. The optimized interaction between the components EPC, MHEV, turbocharger, the engine itself, and the tiptronic transmission supports this effect.

Two SCR catalytic converters interact: the exhaust gas aftertreatment

For exhaust gas aftertreatment, Audi uses twin-dosing technology based two SCR catalytic converters working together. The first of these is located directly behind the manifold in the exhaust gas system, where it also functions as a particulate filter. The second is located further away from the engine under the vehicle floor. Both catalytic converters complement each other's effects because they cover different operating situations and exhaust gas temperature windows. The SCR catalytic converters are supplied with the AdBlue urea solution from a 24-liter tank. Thanks to twin-dosing technology, the SQ5 TDI (combined fuel consumption in l/100 km*: 7.0-

7.0 (33.6-33.6US mpg); combined CO2 emissions in g/km*: 185-185(297.7-297.7g/mi)) comes in substantially below the limits of the new "Euro 6d ISC-FCM AP" emissions standard, which also stipulates a dramatic reduction in NOx emissions in the real driving test conducted on public roads in everyday traffic situations.

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.

Sport differential: more torque, no understeer, greater dynamism

On request, Audi can fit the sport differential on the rear axle, which actively controls the distribution of torque between the wheels when the driver adopts a sporty driving style. It sends more torque to the rear wheel on the outside of the curve that has better grip - literally pressing the car into the curve and reducing understeer considerably. The rear wheel on the outside of the curve also receives more torque when the car is accelerating out of tight-radius curves to further improve driving dynamics.

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 dynamic steering system is another option module. It uses strain wave gearing to vary the steering ratio as a function of speed and steering angle - from direct and agile at low speeds to less direct and smooth on the freeway.

The updated Audi SQ5 TDI (combined fuel consumption in l/100 km*: 7.0-7.0(33.6-

33.6 US mpg); combined CO2 emissions in g/km*: 185-185(297.7-297.7g/mi)) is fitted with 20-inch aluminum wheels with tires in the size 255/45 as standard. Alternatively, 21-inch wheels are available from Audi or Audi Sport GmbH. Six-piston aluminum brake calipers on the front axle grip discs with a diameter of 375 millimeters (14.8 in). The black calipers (red optional) sport S logos.

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. Customers have a choice of nine exterior paint finishes. The black styling package, which adds sporty accents, is available on request.

The latest lighting technology: digital OLED rear lights

Audi offers the new digital OLED technology as an option for the rear lights of the top Q5 model. The OLED rear light is split into three tiles of six segments each. When ordering their vehicle, customers can choose from three rear-light signatures, each with its own specific designs for coming and leaving home. When the Audi drive select mode "dynamic" is activated, the lights change to yet another signature. The OLED rear light also has a proximity detection function that activates all the OLED segments if a road user approaches a stationary SQ5** from the rear to within less than two meters. Dynamic turn signals round out the spectrum of digital OLED rear lights.
