Audi 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.

Audi's diesel-electric supercar is codenamed 'Scorpion'

Speculation continues as to the final nature of the diesel-hybrid Audi supercar said to arrive in 2016 or 2017. A previous report in Automobile had the halo coupe, based closely on the R18 etron quattro endurance racer, codenamed R20 and pegged to look like a Le Mans winner for the street with around 700 horsepower and 737 pound-feet of torque from a twin-turbo V6. Now Car and Driver has updated the gossip with a report that the car is internally called "Scorpion," and it will be even closer to the R18 than supposed.
CD says the heart of the car will use the R18 etron quattro's carbon fiber tub and its engine will be "taken directly" from the race car. That means a 3.7-liter V6 with a single turbo that, in ACO-spec restricted form, outputs 500 hp and 625 lb-ft - CD suspects production output could get to 600 hp - and drives the rear wheels, aided by hybrid motors driving the front wheels. And remember, at Le Mans the R18's hybrid motors can't kick in until they're above a certain speed in order to prevent Audi from getting an advantage coming out of slow corners. A street car wouldn't face that restriction.
The Scorpion would be a fulsome and undiluted example of the technologies Audi has created during its return to sports car racing. Its exterior design hasn't been finalized, with CD citing either the convoluted concept of "a retro take on the future of racing" or packaging that would adhere to the R18's looks. To make sure it is properly appreciated and sells well, production could be limited to the same 333 units as the R8 GT and A1 Quattro.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.
