Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.

Audi introduces frugal, 43-mpg Q7 Ultra in Europe

As Audi's largest model, you wouldn't expect the Q7 (standard 2017 model pictured above) to get very good fuel economy. But the new flagship crossover is a lot lighter than its predecessor. And now the German automaker is rolling out an even more efficient version. In Europe, at any rate. Bearing the designation that distinguishes the most fuel-efficient models that Audi offers, the new Audi Q7 Ultra 3.0 TDI Quattro packs a more frugal version of the 3.0-liter V6 turbo diesel. In Ultra spec, it produces 218 horsepower instead of 272, and 369 pound-feet of torque instead of 443. In exchange, it returns better fuel economy – now quoted at the equivalent of 42.8 miles per gallon (compared to 41.3 for the more potent version). That's not half bad for a crossover this large, even if it is on the European efficiency test, which returns higher numbers than what we're used to in the US. Of course, burning less fuel comes at a bit of a performance penalty: instead of 6.3 seconds, it now takes 7.1 seconds to reach 62 miles per hour from a standstill. Top speed is quoted at just over 134 miles per hour, down from 145. Of course, the E-Tron hybrid will be the most efficient model in the Q7 range, returning the equivalent of over 117 miles per gallon while reaching 62 in six seconds flat. That is, when it starts reaching dealers next spring. The kicker here is that while the hybrid is likely to emerge as the most expensive model in the range, the Ultra is the least. Its base price in Germany comes in at 58,000 euros, compared to 61,890 for the more potent TDI. Combine that with the fuel savings, and the Q7 Ultra is looking like the frugal choice indeed. New Audi Q7 as a highly efficient diesel - The Audi Q7 ultra 3.0 TDI quattro now available for order - Combined fuel consumption is 5.5 liters of fuel per 100 km - Base price is 58,000 euros in Germany An exceptionally efficient diesel version of the new Audi Q7 is launching on the market, which customers can now order: the Audi Q7 ultra 3.0 TDI quattro*. This engine not only reduces fuel consumption to 5.5 liters diesel per 100 km (42.8 US mpg); it also reduces the entry-level price for the Q7 model series to 58,000 euros. Audi will be delivering cars to dealers in Europe starting in September. The efficiency is ground-breaking: The combined fuel consumption of the 3.0 TDI with 160 kW (218 hp) is just 5.5 liters of fuel per 100 km (42.8 US mpg).
