Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.

F1 title fight gets closer | 2016 US Grand Prix recap

We ran into an old friend at the US Grand Prix: an on-form Lewis Hamilton. Reliability and proper clutch actuation helped the Mercedes-AMG Petronas driver resurrect the kind of performance we haven't seen since July at the German Grand Prix. After demolishing the previous qualifying record around the Circuit of the Americas, he put the field in his mirrors as soon as the lights went out, was never bothered by anyone behind, and crossed the finish line 4.5 seconds ahead of teammate Nico Rosberg. The drive was exactly what Hamilton needed to keep his molecule-thin Championship hopes alive. Rosberg, however, did exactly what he needed to do as well by finishing second. The German had a sketchier path to the checkered flag than Hamilton, getting pushed back to the third at the start by Red Bull's Daniel Ricciardo. Worse, Ricciardo appeared to have the pace to keep Hamilton honest ahead and hold Rosberg behind. Red Bull and Mercedes matched one another's pit stops, and it was clear the German would need more help to pass the Aussie. Rosberg didn't have to make his own luck, Ricciardo's teammate Max Verstappen made the luck for him. Ricciardo pitted on Lap 26, ceding second position on track to Rosberg. On Lap 30, Verstappen's gearbox failed while headed down the back straight. The Dutch teenager said the team told him to try to get the car back to the pits, so he dawdled through a few corners before following more team orders to pull over and park. Verstappen's parking spot and bad gearbox meant marshals couldn't push the car off the track, they needed to use a crane. That brought out a Virtual Safety Car, slowing the whole race down and allowing Rosberg to run a longer stint while losing less time on old tires. When the German came in for new tires on Lap 31 he emerged ahead of Ricciardo, and they ran that way to the end of the race, much to Ricciardo's disappointment. Sebastian Vettel claimed fourth for Ferrari, a placing perhaps due only to Verstappen and Kimi Raikkonen retiring from the race. An otherwise anonymous weekend for the scuderia called attention to itself on race day when Raikkonen had to call it a day after a botched pit stop, and Vettel couldn't make any impression on the teams ahead. Fernando Alonso rode home to a brilliant fifth for McLaren. During the first stint while rummaging around outside the top ten, the Spaniard complained about his lack of pace. By Lap 15 Alonso was tenth, on Lap 34 he was eighth.
