Are supercars becoming less special?

There's little doubt that we are currently enjoying the golden age of automotive performance. Dozens of different models on sale today make over 500 horsepower, and seven boast output in excess of 700 hp. Not long ago, that kind of capability was exclusive to supercars – vehicles whose rarity, performance focus, and requisite expense made them aspirational objects of desire to us mortals. But more than that, supercars have historically offered a unique driving experience, one which was bespoke to a particular model and could not be replicated elsewhere. But in recent years, even the low-volume players have been forced to find the efficiencies and economies of scale that formerly hadn't been a concern for them, and in turn the concept of the supercar as a unique entity unto itself is fading fast. The blame doesn't fall on one particular manufacturer nor a specific production technique. Instead, it's a confluence of different factors that are chipping away at the distinction of these vehicles. It's not all bad news – Lamborghini's platform sharing with Audi for the Gallardo and the R8 yielded a raging bull that was more reliable and easier to live with on a day-to-day basis, and as a result it went on to become the best-selling Lambo in the company's history. But it also came at the cost of some of the Italian's exclusivity when eerily familiar sights and sounds suddenly became available wearing an Audi badge. Even low-volume players have been forced to find economies of scale. Much of this comes out of necessity, of course. Aston Martin's recent deal with Mercedes-AMG points toward German hardware going under the hood and into the cabin of the upcoming DB11, and it's safe to assume that this was not a decision made lightly by the Brits, as the brand has built a reputation for the bespoke craftsmanship of its vehicles. There's little doubt that the DB11 will be a fine automobile, but the move does jeopardize some of the characteristic "specialness" that Astons are known for. Yet the world is certainly better off with new Aston Martins spliced with DNA from Mercedes-AMG rather than no new Astons at all, and the costs of developing cutting-edge drivetrains and user interfaces is a burden that's becoming increasingly difficult for smaller manufacturers to bear. Even Ferrari is poised to make some dramatic changes in the way it designs cars.

Evo drives the Audi R18 E-Tron Quattro on track

Audi invited Evo scribe Richard Meaden to the Misano circuit in Italy to drive the Audi R18 E-Tron Quattro - and not just any R18 Quattro, were such a thing possible, but the No. 2 car that took first place at Le Mans this year driven by Marcel Fassler, Andre Lotterer and Benoit Treluyer. Meaden got just four laps in the diesel hybrid racecar - a warm-up, two hot laps and a cool down lap - so this wasn't about testing the R18 E-Tron's limits. In fact, Meaden makes it clear that such a thing isn't even possible for less than a professional driver; when driving at his limits (admittedly in Audi's very expensive car being watched by dozens of Audi engineer eyeballs), the data showed he was using 60 percent of the pedal effort of the professionals. Nevertheless, Meaden does have a lot to say about how the car delivers its massive ability, and with the wide-view shot of the cockpit we also get to see how busy and how intimate an endurance driver's office is.

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.
