Audi R8 Spyder looks like heaven at the Green Hell

After Audi took the wraps off the new R8 coupe at the 2015 Geneva Motor Show, we knew it would only be a matter of time before the convertible version arrived. Now, we've spotted the droptop during testing on and around the venerable Nurburgring Nordschleife in Germany. The new Audi R8 Spyder is expected to closely mirror the fixed-roof supercar we've already seen. Only instead of a tin top, of course, it'll have a folding fabric roof mechanism. This goes against the recent retractable hardtop trend, and the featured is used by the Ferrari 488 Spider and McLaren 650S Spider. Some revised air vents appear to be part of the R8's convertible package, as well. Otherwise, we can anticipate the same specs as the R8 coupe. The latest model ditched the previous version's V8 engine in favor of 10-cylinder options: a 5.2-liter V10 with either 533 horsepower in "base" spec or 602 hp in the V10 Plus model. Both drive all four wheels through a seven-speed dual-cluch transmission. The jury's still out on whether Ingolstadt will slot a smaller engine option into the R8, particularly for markets where tax brackets are determined by engine displacement. But whatever the coupe gets, the convertible is likely to offer it as well. Related Video:

Audi A5 and S5 Sportbacks look slinky for the Paris Motor Show

Following closely on the heels of the updated Audi A5 and S5 refresh, the German automaker introduced the 2017 Audi A5 and S5 Sportback. The vehicles are set for an official debut at the Paris Motor Show next month and share many of the same exterior touches as the regular coupes. Audi's sportback models are not sold in the US. A spokesman from Audi told Autoblog that the automaker is still deciding whether to bring the vehicles to the US. The A5 and S5 Sportback are aimed at drivers that want the same feel as the coupe with the added functionality of a hatchback – think wagon meets sedan. Besides the extra set of doors, there's very little that differentiates the sportback models from the coupes. The new models are built upon Volkswagen's MLB platform, which makes the car roughly 190 pounds lighter than the outgoing model. European customers will be able to choose between two TFSI and three TDI engines for the A5 Sportback. The engines range from a 2.0-liter inline-four that makes 190 horsepower to a 3.0-liter turbocharged diesel V6 putting out 286 hp. The engines can be paired to a six-speed manual transmission, seven-speed S tronic dual-clutch gearbox or an eight-speed tiptronic unit. Front-wheel drive is standard, with all-wheel drive as an available option on two variants. AWD comes standard when opting for the more powerful engines. The vehicles will also feature Audi's new Quattro Ultra all-wheel-drive system that can disconnect the rear wheels to be more fuel efficient. The S5 Sportback is the one enthusiasts will enjoy as it packs a turbocharged 3.0-liter V6 that's good for 354 hp and 369 pound-feet of torque. Audi claims the S5 Sportback, even with the addition of its new doors, will be able to get to 62 mph in 4.7 seconds, which is the same time as its two-door counterpart. In addition to the diesel and gasoline-powered vehicles, the A5 Sportback g-tron will be offered for drivers looking for flexible fuel choices. The g-tron model is powered by a 170-horsepower, 2.0-liter turbocharged-inline-four that can run on Audi e-gas, natural gas or regular gasoline. The exterior design is nearly identical to that of the coupes with Audi's new single frame grille and muscular front end. The rear incorporates a fastback-like design, similar to the one found on the A7, which helps soften the vehicle out – all sport in the front and luxury in the rear.

Audi R8 LMS GT4 debuts in New York, a ready-made race car

The new Audi R8 LMS GT4 race car has made its debut at this year's New York Auto Show. Since 2009, the Audi R8 LMS GT3 has been available for customer purchase, but this new model is intended to be even more affordable. LMS GT-class racing is some of the most entertaining out there. Unlike racing series such as Formula 1, NASCAR, or even the World Rally Championship, GTE, GT3, and GT4 cars are still based heavily on cars you can find on dealer lots today. The GT4 class was created to have a true entry-level racing series. Homologation keeps the cars closer to their production counterparts than any of the other GT classes. Engines, bodywork, and suspension are all similar to production versions, though substantially beefed up for racing. In the case of the Audi R8 LMS GT4, more than 60 percent its parts are shared with the R8 coupe. That means parts are plentiful and relatively affordable. There are some significant changes between the production and racing versions. First, the V10 in the road car is actually far more powerful. The R8 LMS GT4 is limited to 495 horsepower, though that can vary slightly to meet different regulations. Also, rather than having Audi's wonderful Quattro all-wheel drive system, the R8 LMS GT4 is rear-wheel drive. Power is sent to the wheels through a seven-speed dual-clutch transmission. Though the car is set to make its debut next month at the Nurburgring 24 Hours, it won't actually be competing until the start of the 2018 season. Audi is simply tuning the car at different tracks before asking for approval at the end of the year. Pricing hasn't been announced, but expect it to fall between the $145,000 of the RS3 LMS and the $450,000 of the R8 LMS GT3. That's not nothing, but in the world of professional racing, it's a relative bargain. Related Video:
