1,682 miles in a 2014 Audi A8 L TDI - Part 2

Interruptions like the Canadian Grand Prix, Le Mans, Pikes Peak, that ridiculous Porsche 911 GT3 and the really good, really outrageous Jeep Cherokee, are among the distractions that delayed the conclusion of this tale. If you'll remember, in Part 1 we started off in a parking lot in Sebring with an Audi A8, headed anywhere that would empty our tank, and after five days in Miami and Ft. Lauderdale and Pompano Beach we bolted in the middle of the night for a breakfast date at an IHOP a couple hundred miles away.
We last left proceedings at a Chevron pump beside the West Florida Turnpike, somewhere around midnight in the humid wilds, having done 660 miles and spent $89.40 to put 20.992 gallons in the great white whale. We had done average speed of 31 miles per hour at an average rate of 27.5 miles per gallon. Those kinds of numbers, as we demonstrated, are good enough to put you in the fuel economy orbit of the Toyota Corolla - to be precise, it only cost $6.40 more to cover that 660 miles in the A8 TDI than it would in the Japanese compact. That led us to conclude that there were just a couple of Starbucks Venti lattes between the A8 and the Corolla, assuming we conveniently ignore the two cars' purchase prices. Turns out we were wrong: it didn't take long for a commenter named "mike" to set us straight when he wrote, "It's clear you weren't lying about not frequenting Starbucks...no way could you get two venti lattes for $6.40." Mike, we salute you - our ignorance of terrible coffee has served the higher purpose of emphasizing the strong case made by the diesel Audi.
But that A8... well, the wheels were still on the damn thing and we had to drive them off. That meant five more days of pilot duty to get us from wherever the hell we were to Wildwood and Daytona Beach, FL, then Brunswick, Macon and Atlanta, GA, then Birmingham, AL, and back to Atlanta.

Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:

Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.
