Subaru WRX STI vs. Audi S3 in compact AWD dustup

It's not every day that a Subaru and an Audi can be reasonably compared head-to-head; the two brands tend not to compete directly in their respective segments. However, the latest WRX STI and the S3 Sedan offer the perfect chance to find out if the working-class Scooby can beat its upper-crust competitor.
The UK's Auto Express gets behind the wheel of these two all-wheel drive performance sedans, or saloons as the Brits call them. Across the pond, both of them are rated at an identical 296 horsepower, but the Subaru edges out the Four Rings on torque. Like in the US, British buyers have to pay a little more to get the Audi, but it comes with a nicer interior and more brand cachet, if that means anything to you.
The video starts out with a fairly standard road test comparing the two of them back-to-back - all fairly subjective. But then Auto Express takes the trip to the drag strip, and the results there are much more conclusive. There's a definite winner when they cross the line, but you have to scroll down to see which of these turbocharged models with rallying heritage wins out.

Audi shows off the Prologue Avant Concept as a plug-in hybrid

The Audi Prologue Avant Concept goes in a different direction than the Prologue coupe, in more ways than just its five-door wagon body. The coupe was first shown at the LA Auto Show with a 4.0-liter, twin-turbo V8, then went redux at CES as a hybrid with a total of 677 horsepower and 701 pound-feet of torque. The only-slightly-larger Prologue Avant sticks with the hybrid but gets the system from the Q7 E-Tron quattro, meaning a 3.0-liter, twin-turbo V6 TDI with 353 hp and a 100-kW electric motor strapped to the eight-speed transmission. Total output is 455 hp and 553 lb-ft, pure electric range is 33 miles, and 0-62 miles per hour comes in 5.1 seconds. The forward section of cabin with its screen-based Tie Fighter displays and controls comes over from the coupe, as well as the four individual seats, but the Avant lavishes attention on rear passengers in ways not possible in the two-door. They also get a screen on the pass-through center console for convenience controls, and detachable OLED screens - a la the detachable tablets in the Q7 - with which they can send information to the front occupants. As a traditional Audi avant is to a coupe relative, the Prologue Avant is all about bringing the family along on the digital highway. We'll see it at the Geneva Motor Show next week, and Audi is again talking up how the design language will migrate to production cars. It also makes noises in the press release below about near-production many of the technologies are in the concept, so it looks like there could be all sorts of Easter Eggs on the way from the Ingolstadt brand.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.
