Audi Q5 Hybrid Cars

Audi will have a new entrant in the hybrid sport utility vehicle market later this year with their Q5 hybrid quattro which Audi claims will have the performance of a six cylinder engine pushing out 245hp with the economy of a four cylinder, getting up to 34 mpg, while riding on the quattro permanent all-wheel drive system and an agile chassis.
Like all Audi's, the Q5 stands out. Its body design comes across as powerful and athletic. It measures 15.19 ft in length and 6.23 ft in width, but only 5.35 ft in height. The tailgate, the fenders and the aluminum sill panel strips bear the hybrid badge. The radiator grille is painted high-gloss black, and the tailpipes feature chrome trims. The exclusive Arctic Silver, metallic paint finish is optionally available.

The optional xenon plus headlights are an elegant setting for the daytime running lights, comprising 12 daylight white LEDs each. The xenon plus headlights can also be combined with the adaptive light cornering light system.

Like the front end, the rear of the Audi Q5 hybrid quattro has a strongly expressive character; horizontal lines accentuate the impression of width. The bumper incorporates the rear fog lights, and the license plate area is recessed into the tailgate. Like the engine hood, the wraparound tailgate is made from lightweight aluminum. It is exceptionally wide, like that of its big brother, the Audi Q7. The undivided rear lights are mounted on the large tailgate. Because they are not visible when the hatch is open, the Audi Q5 hybrid quattro has auxiliary lights in the bumper. The main lamps have bulbs housed in separate chambers as standard; Audi uses light-emitting diodes in the optional xenon plus headlights.
The Q5 hybrid comes with 19-inch cast aluminum wheels feature a ten-arm turbine design, with their spokes resembling turbine blades. The wheels are fitted with 235/55 tires. Audi offers optional wheels with 19- and 20-inch diagonals; an S line bumper is available from quattro GmbH.

Inside Audi will offer the option of sport seats with manual angle adjustment, extendable thigh rest and electric four-way lumbar support. The climate-controlled comfort front seats have a seat back and base cushion that have two small fans with six power settings. To prevent chilling of the occupant, there is a supplementary function that cuts in automatically, if need be. The climate-controlled comfort seats are upholstered in perforated leather.

All functions in the Audi Q5 hybrid quattro are focused on the person at the steering wheel. The center console, which is subtly angled to the left, comprises a unit with the instrument cluster. It features an innovative display concept that renders the individual driving states of the hybrid drive clear-cut and tangible. The tachometer has been replaced by a “power meter,” with a needle that indicates the total system output on a scale of 0 to 100 percent. A second scale is divided into colored segments, whose green and orange sections show at a glance how the Q5 hybrid quattro is currently traveling – with a greater share of electrical power or combustion engine power. An additional instrument displays the charge level of the battery.
At the same time, the color display of the driver information system and the large monitor of the standard MMI navigation plus show the operating states and power flows in the hybrid system in elegant graphics with a three-dimensional effect. The MMI monitor also displays differentiated consumption and recuperation statistics in easily understandable bar graphs.

There are numerous convenient features for both driver and passenger. The spacious door pockets have brackets that are also suitable for large bottles. Then there are two more cup holders on the center tunnel. One of them is optionally available as a thermal cup holder. An electronically controlled peltier element – an electrothermal converter similar to the principle found in a cooler bag – operates in tandem with a fan. At the push of a button, it cools or heats the inside of the thermal cup holder across a range from 3 to 58° Celsius (37.4 to 136.4° F). A small display serves as a visual reminder for the user when the cup holder is hot.

The climate control system of the Audi Q5 hybrid quattro has been adapted to the requirements of electric driving. The air conditioning compressor has a high-voltage electric drive. Demand-controlled for high efficiency, the compressor ensures AC operation even when the combustion engine is shut down. An electric auxiliary heater supports interior heating.

The optional S line sport package immerses the interior in cool black, with the inlays in matt aluminum or black piano finish providing subtle contrasts. The sport seats are upholstered in cloth/leather or a combination of perforated Alcantara and leather. The steering wheel, gear lever gaiter and floor mats have a special design. Cast aluminum 19- or 20-inch wheels further enhance the dynamic appearance of the Audi Q5 hybrid quattro.
Under the hood the 2.0 TFSI in the Audi Q5 hybrid quattro has a displacement of 1984 cc. Its output is 211 hp with the maximum torque of 258.15 lb ft permanently available at 1,500 to 4,200 rpm. The 4-cylinder engine combines direct injection with turbocharging which is typical for Audi who has a philosophy of downsizing, which replaces displacement by forced induction. The Audi valvelift system (AVS) further increases power, torque and efficiency by switching the stroke of the exhaust valves between two stages depending on the load and rpm.

A secondary air system at the cylinder head makes sure that the exhaust gas treatment cuts in particularly fast. Integrated in the engine control unit, the hybrid manager controls the efficient change and smooth transitions between the operating modes, and was fully developed by Audi alone. The optimal interplay between the combustion engine and the electric motor briefly results in a peak system output of 245 hp and a maximum system torque of 354.03 lb ft.

The Audi Q5 hybrid quattro applies its power to the road via the quattro permanent all-wheel drive system. The enhanced traction, road dynamics, safety and directional stability that it delivers together make up Audi's proverbial “Vorsprung durch Technik.” The five-link front suspension, with an ample track width of 63.98 in, is a big factor in the dynamic character of the Audi Q5 hybrid quattro. Because the development engineers moved the differential further forward up the driveline and the clutch further back, the axle could be positioned far to the front. This configuration permits an optimal weight distribution between the front and rear axles.

An electromechanical unit serves as the steering system, with a small electric motor generating the power. The system operates at high efficiency, since it need not consume any energy in straight-ahead driving. Configured as a speed-dependent power steering system, it requires only little effort from the driver to maneuver into a parking space thanks to the high servo boost. At higher speeds it trims back the boost level for a superbly calm response on the freeway.

Audi will ship its new hybrid SUV equipped with aluminum wheels in two sizes, 19 and 20 inches. Measuring 19 inches and shod with 235/55 tires. Audi will offer 17-inch and 20-inch winter wheels.The large wheels of the Audi Q5 hybrid quattro conceal brakes that are easily up to whatever braking tasks they may be confronted with. All four disks – measuring 345 millimeters (13.58 in) in diameter at the front and 330 millimeters (12.99 in) at the rear – are vented.

The Q5 hybrid comes with high-performance brake pads that achieve high, stable coefficients of friction and are only minimally susceptible to fading even under extreme loads. The vented front disks will no longer have any conventional cooling ducts. Instead, the two halves of the disk are joined together by hundreds of small metal cubes that are able to dissipate a high volume of hot air very rapidly.

The Audi Q5 hybrid quattro should be a great car for an active lifestyle. It will be efficient, dynamic, spacious, multifunctional and comfortable. It will be appearing in Europe in the fourth quarter of 2011 at a starting price of $78,745.00.
