Audi A8 could spawn Mercedes-Maybach S600 rival

Five years ago, there was no middle ground for big luxury sedans. You either bought a $100,000 Mercedes-Benz S-Class, Audi A8, or BMW 7 Series, or you spent $225K on a twelve-cylinder Bentley Continental Flying Spur. But today, the market is changing. Bentley sells a V8-powered Flying Spur for around $200,000 and Mercedes is successfully selling a longer, twelve-cylinder, ultra-lux S-Class for $190,000. The middle ground is growing, and Audi wants in on the action. Audi is looking closely at the Mercedes-Maybach S600, according to Dr. Stefan Knirsch, the company's new technical leader. The company recently introduced a one-off A8 limo, shown above, although we'd imagine an S600 rival would be a more manageable size. "We are thinking about it," Knirsch told AutoExpress at the launch of the new SQ7. "The success of the extra-long version of the S-Class has got us wondering about whether there could be a business case for that in the future." Knirsch's comments raise a number of questions about a potential ultra-lux A8. Would it be longer than the A8L? The extra backseat space is a key part of the Maybach S600's appeal. What about the badge? Audi doesn't have a nameplate to rival Maybach to distinguish such an exclusive A8 from its more affordable siblings. Will the Audi offer more or fewer shades of black/silver than the S600? But the biggest question is what a bigger, more luxurious A8 could mean for the rest of the A8 range. As AE explains, Mercedes has done a remarkable job of fleshing out the S-Class range, with the normal sedan, Maybach, Coupe, Cabriolet, and their accompanying AMG variants. The Maybach S600 started that process – could an extra-large competitor kickstart Audi's full-size luxury expansion? The A8 has long been subject to gossip that it'd spawn an A9 Coupe (2014's Prologue Concept only fed that particular rumor mill), after all. Beyond hinting at a more luxurious A8, Knirsch expounded on another piece of exciting news: the next A8 will get Level 3 automation. That would mean full driverless ability "with the expectation that the human driver will respond appropriately to a request to intervene," according to the SAE's official definition. While Audi confirmed last year that the A8 could drive itself at speeds up to 37 miles per hour, Knirsch's more specific comments make it sound like the system could be even more advanced than originally thought.

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.
