Weekly Recap: Car-pedestrian crashes remained elevated in 2014

The death of American Horror Story: Freak Show star Ben Woolf served as a reminder this week that car crashes involving pedestrians remain a problem, and a new study issued on Thursday reinforced that the situation isn't really getting better. The Governors Highway Safety Association found a slight decline, 2.8 percent, in the number of pedestrian deaths in the first six months of 2014. Fatalities dropped from 2,141 to 2,125 compared with the same period in 2013, though the association says it's a statistical wash when factoring in undercounting. Deaths are still 15-percent higher than in 2009. "The number of deaths remains relatively high and is cause for concern," wrote Allan Williams, who compiled the report and is the former chief scientist at the Insurance Institute for Highway Safety. This is the first look at data from last year, and the National Highway Traffic Safety Administration will issue its full-year results later. The GHSA found some progress on the roadways, as 24 states and the District of Columbia reported drops in pedestrian deaths. In some states, the problem isn't even a problem at all: Nebraska and Wyoming reported one fatality apiece, though large population centers in urban areas are where most accidents occur. "This is a clearly a good news, bad news scenario," Jonathan Adkins, GHSA executive director, said in a statement. "While we're encouraged that pedestrian fatalities haven't increased over the past two years, progress has been slow." Other News & Notes Cadillac previews CT6 during Oscars Cadillac previewed its upcoming flagship sedan, the CT6, in commercials that aired Sunday during the Oscars. As expected, the creased sedan carries on Cadillac's recent design language, and the car in the commercial looks like a larger version of the CTS and ATS sedans. The CT6 will be revealed this spring at the New York Auto Show and launch late this year. It will be assembled at General Motors' Detroit-Hamtramck factory on a rear-wheel-drive chassis, and the CT6 is the first car to use Cadillac's revised alpha-numeric naming scheme. The commercials also kicked off Cadillac's "Dare Greatly" campaign, which is the first with its new advertising agency, Publicis Worldwide. Honda unexpectedly changes CEOs Honda unexpectedly announced this week that it will change CEOs. Current chief Takanobu Ito will step down in June and be replaced by company veteran Takahiro Hachigo.

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.

2018 Audi A5 and S5 Sportbacks are coming to America

Fans of hatchbacks have cause for celebration, because Audi confirmed the 2018 A5 and S5 Sportback models are coming to the US. The five-door variant of the classy A5 coupe and convertible line will appear in America this spring. Pricing was not announced. While we will be getting the hatchback, we won't get every powertrain option offered in Europe. Those versions will be offered with an array of gas and diesel engines, and some will be available with a manual transmission. We'll only get two engines here, and they both come with automatics. The standard A5 Sportback will come with the same turbocharged four-cylinder as the A5 coupe and convertible and the A4 sedan. It makes 252 horsepower and 273 pound-feet of torque of torque and is paired with a seven-speed dual-clutch transmission. The S5 Sportback gets the same 354-horsepower turbocharged V6, which also makes 369 lb-ft of torque and sends power through a conventional 8-speed automatic. Both Sportback models are nearly as fast as their two-door siblings, reaching 60 mph in 5.7 and 4.5 seconds respectively. That's just a tenth of a second slower than either coupe. The Sportback also has one more difference compared with the European version. All American A5 Sportback models will come with Audi's Quattro all-wheel-drive. The Sportbacks feature similar interiors to their coupe and convertible brethren, along with the same infotainment options. This includes the available Virtual Cockpit LCD instrument panel and MMI system. Of course the biggest difference between the Sportback and the two-door models is space. Audi claims the Sportback has twice as much cargo room as the coupe. And the back seat will obviously be much more comfortable and usable. View 14 Photos You don't sacrifice too much in style, either. The A5 coupe's distinctive, Coke-bottle character line has made the transition to a longer profile gracefully, and it's complemented by the greenhouse inspired by the bigger A7 Sportback. So if you've always wanted an A5 for its looks, but felt you needed something more practical, you won't have to compromise with the Sportback. Related Video:
