Audi A4 Avant

Audi ' s new station wagon, the A4 Avant, gets its cosmos premiere character two weeks at the Geneva motor splash. And when the new wagon bows, heartfelt will bring a new " soaring - powered, four - drainpipe turbocharged appliance " to the celebration, according to knowledge released by Audi.

Audi will launch its North American diesel abusive protect the Q7 3. 0 TDI arriving close January and the A4 3. 0 TDI that will supersede within a second ( VW ' s Touareg twin will prompt the new V - 6 seeing robust ). Naturally, congress the cosmos ' s most stringent diesel emissions regs ( those of the five California - emissions states ), the machine is a technological tour de impetus. Fix neatness to kindle every atom of diesel fuel as completely, cleanly, and efficiently thanks to possible, the apparatus uses au courant piezo - electric injectors stifle eight diminutive drench holes each.

This fall, both the new - engendering A4 sedan and the A4 Avant roll in force the U. S. And week the sedan again will offer a 265 - compulsion narration of Audi ' s 3. 2 - liter V - 6, the Avant wagon arrives unequaled at launch protect the new four - drainpipe, Audi noted force its release.

Power other markets, ace will copy smaller gasoline and diesel engines offered, among them a 240 - hp 3. 0 - liter turbodiesel six.

By injecting the fuel at 29, 000 psi over the course of five or larger mini squirts per blaze revolution, cylinder pressures rise gently, preventing the marbles - agency - a - blender clatter of ancient diesels. The engine computer monitors warmth by mapping this rise prominence cylinder pressures during every circuit connections regularity to quantify the fuel standard, which varies more widely in the U. S. than in Europe. Our cetane numbers range from 39 to 53, in contrast to Europe ' s, which are regulated to a minimum of 51 ( the higher the number, the sooner combustion is initiated, so the fuel burns longer and more completely for improved performance and emissions ).

Six - speed transmissions will be offered and quattro will be standard on U. S. - market Avants, Audi confirms.

Audi says its Avant will be the most successful premium wagon in its class. With the new generation, the Avant inherits the deep grille, sweeping roofline and the somewhat controversial interior styling of the new A4 sedan. Inside, the new cockpit adopts the styling of the A4 sedan and the new A5 / S5 coupes, with a deep binnacle shading a touchscreen interface.

The 3. 0 TDI ' s single variable - nozzle turbocharger is optimized for greater torque at a slight cost to horsepower relative to the European - spec TDI, and it feeds twin intercoolers. Except, that is, when hotter intake is required for emissions purposes, at which point the intercoolers are bypassed. Once the pretty clean exhaust leaves the turbo it is further scrubbed by an oxidation catalyst, a particle filter, and a NOx - reduction catalyst. It also flows past an oxygen sensor, four temperature sensors, and two new Siemens NOx sensors.

Audi also promises better functionality with the new Avant. A new suspension design on the sedan and wagon translates into better weight distribution, while the reconfigured proportions of the vehicle mean shorter front overhang with a longer wheelbase. The new wagon sits more than 4. 7 inches longer than the previous version, though it ' s 10 percent lighter and more rigid than before, Audi says.

The latter provide closed - loop control of the urea injection system that completes the job of reducing NOx emissions by 90 percent. This 32. 5 - percent urea / water solution is carried in two tanks with a total capacity of 6. 1 gallons ( one tank is heated, as the solution freezes at 12 degrees F ).

With a cargo hold of up to 50. 5 cubic feet, Audi says its wagon is the best carrier in the class that also includes the small wagons from BMW and Mercedes - Benz. A split - folding rear seat is standard, while a power tailgate is a new option.

Safety features include curtain airbags for both rows of riders; anti - lock brakes, stability and traction control. Features such as a rear parking assist; a lane - departure warning system; and a blind - spot detection system will be available as options, as will adaptive cruise control.

That ' s enough to last a minimum of 10, 000 miles. It ' s refilled via a special inlet next to the diesel filler during regularly scheduled maintenance stops, and it should sell for about the price of windshield - washer fluid.

Other options will include Audi ' s navigation system, bundled with the multimedia interface ( MMI ); iPod connectivity; Sirius satellite radio; a panoramic sunroof; and in some markets, a Bang & Olufsen audio system.
