Chevy Corvette Z06, Ford F-150 Raptor join Lego Speed Champs

Get ready to park some performance machines on your desk: Lego's 2016 line of Speed Champions kits will add seven new vehicles for next year, according to an update to the database Brickset. These include some serious muscle like a Chevrolet Corvette Z06 and Ford Mustang GT. There's also a listing called "Chevrolet Camaro Drag Race" and a very cool combo titled "Ford F-150 Raptor Ford/Model A Hot Rod". Fans of European performance don't need to be jealous, though. The database shows a kit called "Porsche 919 Hybrid and 917K Pit-Lane." Plus for fans of the Four Rings, the Audi R18 E-Tron Quattro and R8 LMS Ultra are also getting their own Lego models. Fourtitude appears to have some leaked shots, if you want to see what these kits will look like. Lego has partnered with Porsche, McLaren, and Ferrari and offers Speed Champions kits for vehicles like the Porsche 918 Spyder, McLaren P1, Ferrari 458 Italia GT2, and LaFerrari. The models in the series aren't as heavily detailed as the massive Mini Cooper or Volkswagen Bus sets, but they make up for that in value. The individual cars retail for a fairly affordable $14.99. The Formula One playset tops the current range at $99.99, but it comes with a truck, racecar and team figures.

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.

VW, Mobileye to bring new automated tech to series production

Volkswagen will bring new automated driving technologies to series production as it deepens its partnership with Mobileye in automotive driving technologies, Europe's biggest carmaker said on Wednesday. Israeli automotive tech company Mobileye will provide driving assistance software based on its SuperVision and Chauffeur platforms to VW's luxury brands such as Audi, Bentley, Lamborghini and Porsche. The technologies, which later will be integrated by VW's software unit Cariad, include assistance systems for highway and urban driving, such as automated overtaking on multilane highways, automatic stopping at red lights and stop signs, and support in intersections and roundabouts. "New automated driving functions will significantly boost convenience and safety," VW Chief Executive Oliver Blume said. Mobileye is also set to supply further automated driving software to Volkswagen's commercial vehicles unit. In future, the German carmaker aims to rely on its own complete in-house software system.
