Audi TT Offroad gets the green light

The TT family already has a coupe and convertible, with various engines available in each. But over the past year or so, Audi has been toying with the idea of expanding the range with another bodystyle. And now the latest report from Car confirms that Ingoldtadt has given the production go-ahead to the TT Offroad concept. Unveiled at the Beijing Motor Show last year, the yellow TT Offroad concept envisioned a high-riding five-door crossover form with trademark TT styling cues. It was preceded by the blue three-door Allroad Shooting Brake concept at the Detroit show and followed by the sleek, red five-door TT Sportbrake concept at the Paris salon later the same year, but the impracticality of both those show cars is what we understand prompted Audi to go with the Offroad concept instead. So if it's a crossover, why not badge it with the letter Q, you ask? Because Fiat, that's why. The Italian automaker owns the names Q2 and Q4, which it has used on a variety of models (particularly Alfa Romeos and Maseratis) to connote their traction system. And though the Volkswagen Group has asked nicely, Sergio Marchionne has been as reluctant to give his biggest rivals a leg up as he has been to part with Alfa Romeo, despite their repeated advances. As a result, word has it that the production version of the TT Offroad concept will be sold as the TTQ, which kinda makes us giggle, but it would at least provide a nomenclature bridge between the TT and Q families within Audi's lineup. That is, unless Audi marketing chief Luca de Meo manages to convince his former boss to part with the Q2 and/or Q4 labels. Whatever it's called, the production crossover coupe would share similar dimensions to the Q3 when it arrives in 2017, but would potentially stand even further apart from its more utilitarian counterpart than the BMW X4 does from the X3 on which it is based.

Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

Audi kills off its 420-hp four-cylinder engine project

Audi's supercar-slapping, fire-breathing four-cylinder concept engine will remain just that, with Autoblog confirming that it has been internally killed off. Speaking at the launch of the TT RS, the engineering boss of Audi's Quattro GmbH division, Stephan Reil, said the Volkswagen Group had stopped all development of the 420-horsepower, 2.0-liter four it showed in the 2014 TT Quattro Sport Concept car (above). Despite previous assurances that Quattro had roles for both the EA888-based engine and Audi's wildly charismatic 2.5-liter, five-cylinder motor, post-Dieselgate reality has killed the smaller engine. "The 400-horsepower EA888 engine is dead," Reil said. The EA888 engine was conceived and developed by the same man behind AMG's powerhouse 2.0-liter four. Friedrich Eichler left AMG to become the Volkswagen Group's gasoline engine development go-to guy, and he was confident the 420-hp engine could be turned into a production car quickly, as was then-Audi development boss, Ulrich Hackenberg. It was even suggested that because the EA888 engine family bolted straight into the Volkswagen Group's ubiquitous MQB small-car architecture, the little powerhouse could be cheaply and quickly dropped into any of the company's cars that needed an image boost. Since then, Quattro has elevated the five-cylinder motor, switching it to an all-alloy block with a magnesium oil pan to cut down its weight while boosting its power and torque levels. Where the four-cylinder engine was shown with 420 hp and 332 lb-ft of torque, the production version of the TT RS's new five-cylinder engine totes 400 hp and 354 pound-feet of torque. The smaller engine's proponents claimed a 0-62 mph acceleration figure of just 3.7 seconds for the concept TT that carried it, and it might not be a coincidence that the all-new TT RS claims exactly the same figure. The 2.0-liter motor had a torque peak that arrived at 2,400 rpm and began to taper off at 6,300 rpm, while its power apexed at 6,700 rpm, thanks in part to a turbocharger that could feed it up to 1.8 bar of air. Flip to the TT RS' data and you're looking at more torque at lower revs and a touch less power, but at higher revs. That's not a lot of wriggle room for the concept engine to operate, especially when the perceived value of the five-cylinder engine is higher than the four, and the four's development and production costs would be higher than the five's.
