Test Drive Audi Q5 since 2008 SUV

Electric line We test the hybrid Audi Q5

Before the new year, I visited Ingolstadt on the Audi test seminar, where the company demonstrated its electrical achievements. In the forefront, there were prototypes of a hot coupe R8 E-Tron and urban hatchback A1 E-Tron. Both electric drives, and they will soon go into production, but besides them, Audi made it possible to get acquainted with the serial Q5 Hybrid, which will be on sale for this year.


The hybrid from the usual Q5 is almost no different. A hybrid is a black glossy radiator grille, ten-spin 19-inch alloy wheels with a special design, Hybrid nameplates around the perimeter and chrome connections of the exhaust system. Bumper s Line can be installed to order

What is it eating? With a lithium-ion battery, a 33-kil-liter traction electric motor, a two-liter turbocharged 211-strong TFSI engine, five times taking the title of the engine of the year, an eight-speed planetary automatic transmission and, of course, with a constant full-wheel drive ...

Before listening to theoretical part about the loss, I sit down behind the wheel and food allocated twisted kilometers on the propirated route with pure brains. That's more interesting. Good, hell! I find out. Feeling as if home slippers returned. I am comfortable here. Beautiful chassis, handling, dynamics are verified and pleasant efforts on management bodies. Before pain familiar reactions. School, in one word. From the usual gasoline version of the hybrid not to distinguish a tactile, even despite the increased to two tons (increase of 130 kilograms) mass.

Towns, villages, looping two-band tracks, a piece of auto. The presence of an electric drive in Q5 gives only an absolutely silent start and the original dashboard. On the left instead of the engine temperature indicator of the battery level scale, and the tachometer is replaced by a pointer demonstrating the modes of operation of the power plant. In addition, a 3D-icon is displayed on the liquid crystal display of the on-board computer, visually showing everything that happens to the drive. By the way, these pictures can be displayed on the MMI multimedia monitor (MULTI Media Interface), located in the center of the console.

The electrottery Q5 can ride at speeds up to 100 km / h. It is clear that the range with an increase in aerodynamic resistance drops significantly. But on a flat autobahn on a constant charge charge of the battery, there are enough three kilometers, provided that the crossover is driving at a speed of 60 km / h. If you select EV mode, then the electric motor will be used for movement. This mode is more suitable for moving in urban conditions in traffic jams or residential neighborhoods. At the same time, the kinetic energy of the car during braking or movement rolling in any case will be returned to the battery traction motor at each slowdown goes into the generator mode. When the battery charge decreases to the critical, the engine will enter into action ...


The main advantages of the hybrid to go on electricity where everything is smoke, and in braking to store the energy of a moving car in batteries to use it again. Hence the best environmental friendliness and efficiency. Conventional kinetic energy of motion during braking is converted to heat using brake mechanisms

In mode D, the optimal energy consumption is carried out during the operation of both motors. Well, what about sports? Catching the selector to S. Gas to the floor! The tachometer arrow shoots into the boost zone. And I immediately get a headrest on the back of the head. Wow, not the exemption to acne from the fact that both engines are now working together. Summary in the peak, they give out 480 Newton meters and 245 horses. For comparison, top gasoline Q5 with V-shaped six 3.2 FSI develops 330 nm and 270 hp And the main competitor of the hybrid Q5 Lexus RX 450H has under the hood 299 hp At the same time, Lexus is heavier to 110 kg, largely due to this and the dynamics of his worse than 7.1 s at Audi and 7.8 in Lexus. Moreover, the difference in the maximum speed is even more noticeable Q5 accelerates to 222 km / h, and not up to 200 as Lexus.


Being one of the components of the modular platform, the Q5 Hybrid drive can also be used in other AUDI models with a longitudinal location of the engine. For example, in new A8, A6, A6 AVANT

But if you continue to compare with Lexus RX 450H, it turns out that the Japanese, despite the greater mass more economical and cleaner: 7.1 liters per 100 km from Audi and 6.3 l in Lexus (and CO2 emissions, respectively, 160 g / km and 148 g / km). Of course, that is not the last merit of the newest Toyotovsky 3,5-liter V6, working on the Atkinson cycle. But there is one nuance on a serious off-road Lexus practically helpless, because there is a separate low-power motor-generator with the rear axle, which is simply not enough on heavy soils (the front axis of Lexus is serviced by a gasoline engine combined with the second motor generator). Audi Q5 is endowed with a full constant full-wheel drive with a blocked inter-axis differential, the transmission digested the total torque of both engines and distributes it between the wheels. That is, in the dirt Audi looks much more confident. In addition, the hybrid Q5 can be a two-tone trailer, as well as its usual gasoline analog.


DVS two-liter turbocharged motor 2.0 TFSI with direct fuel injection, it produces power 211 hp (155 kW) and develops the maximum torque of 350 nm in the range from 1500 to 4200 rpm. Gas distribution mechanism with phase inspears and the AVS valve length of the AVS valve length adjustment system (Audi Valve Lift System). Since the engine is periodically turned off, the air conditioner compressor actuator and the cooling system pump had to be made electrical. The brake amplifier also received an electropneumatic drive. Drives are powered by a traction battery.

On the street +5. Weave with a skuffing speed in the center of the next German settlement, and I have a feeling of distillation. DVS plucked, signs of life gives only a climate installation rustling fan, tries, withstands the specified temperature and humidity. Air conditioning and electric heater work the brake system with a vacuum amplifier also retains its performance. In addition, in the planetary transmission, it continues to force the oil forcibly to circulate this is vital for it. The pumps of all these systems and aggregates are not given from the crankshaft of the internal combustion engine, but with the help of electric motors. Their, as well as all other side electromotives, electricity provides a loading battery.

By the way, she is lithium-ion-iron here and is located in the back of the body, under the trunk floor, but so that the useful volume of the latter has almost suffered. Batteries for Audi supplies Sanyo, service life of 10 years, temperature at which they can fully operate, minus 10c. It occupies a battery along with fastener and the system of air ducts for cooling 80 liters of space, and its weight is 38 kg. The battery consists of 72 cells, the operating voltage on the terminals of 266 volts, the capacity of 1,3 kWh. The battery has an air cooling system, and the air conditioning system can be used to cool the air supplied between the cells. The cooling circuit of the battery received its evaporator, but the branch is connected to the main climate control system. If the battery temperature exceeds + 55c (for example, if the car has been in the sun for a long time or operated in heavy temperature conditions with a large number of cycles of braking and braking cycles), the electric drive will automatically turn off (otherwise there will be a threat of explosion of cells from overheating). In this case, Q5 Hybrid will be able to move only under the action of DVS. In general, the car is complex, interesting and dynamic. The main thing is that the hybrid did not lose the family traits.

Q5 Hybrid Another Audi step to electric cars. Only this step, consider, already captured in serial production in Europe, the hybrid crossover will appear during the year. In Russia, it is also going to sell it. And in general, the electromotive prospects of the German company are as follows in 2012, Audi plans a limited series to release the E-TRON sports electroceupene, which will be completely on the electric shirt. Several earlier in the series will appear the city compact A1 E-Tron. It will occupy an intermediate position between Q5 Hybrid and R8 E-Tron. In fact, a unit of an electric car capable of charging from the household network, but it carries on board the waf of Vankel and the generator to replenish the battery charge. The power plant of the bug has no connection with the wheels.

Hybrid Audi Hybrid Drive
By the way, behind the shoulders of Audi over 20 years of experienced developments in the field of hybrid technologies. The debut of the Audi Duo of the first generation (from above) took place in 1989: the concept car was created on the basis of Audi 100 Avant. The five-cylinder gasoline engine led the front axis, a temporarily connected electric motor with a capacity of 12 hp (9 kW) rear.
