Speaking of new transmissions, Audi has created a continuously variable type (CVT) - dubbed Multitronic - for use in their front-wheel drive A4 1.8T - the new base model. How does it work? Rather than increasing engine revs over repeated intervals between gear changes, the CVT allows the engine to remain at a constant rev range, manipulating the final drive seamlessly from within the transmission. Just like a snowmobile, you keep going faster just by applying the throttle. Why a new type of transmission? The performance numbers speak for themselves. The Multitronic is 1.3 seconds quicker than Audi's Tiptronic transmission and 0.1 second faster than the manual gearbox in 0-100 km/h tests. What's more, fuel economy improves by 0.94 km/L (2.2 mpg) over the automatic and 0.21 km/L (0.5 mpg) better than the standard. Audi's Multitronic CVT was recently awarded "Best New Technology" by the Automobile Journalists Association of Canada (AJAC) at their annual Car of the Year test-fest.
Awards honoring Audi vehicles are nothing new. The quattro Coupe was made legendary by annihilating its WRC rally competition in the early 1980's. The A4 repeatedly took title to the prestigious European Touring Car Championship until its quattro AWD was disqualified due to an 'uncompetitive advantage'. Active safety is important, but Audi doesn't forget that accidents are occasionally unavoidable. Therefore the A4 comes with front and rear side-impact airbags and OnStar.
Audi's interior treatment is as attractive as its exterior. Standard equipment includes the usual luxury features such as power windows, mirrors (with heat), and locks that include keyless entry. The A4's dual climate control includes an A/C smog sensor that automatically changes from fresh to re-circulate when exterior air becomes foul. Other unique features include side-rearview mirrors that automatically dim and turn signals that stay on for only three flashes when lightly pressed, or continual when fully engaged. The Audi's seats are first rate too, with improved rear legroom. As comfortable as the A4 is, be careful when getting in. If it's been raining, water will collect in the door sills and immediately gush out when opened. While this doesn't seem to be a major problem, you might get your shoes and socks wet.
