Ed Welburn leaves a lasting legacy at GM design

General Motors design chief Ed Welburn retired July 1, and the soft-spoken stylist is leaving a lasting legacy at the automaker and on the industry. He became the first African American to lead design at a carmaker when he took over GM's top spot in 2003. Just six people have overseen the company's design, and Welburn followed in the footsteps of icons like Harley Earl and Bill Mitchell. When Welburn was given expanded global oversight in 2005, it wasn't ceremonial. He helped unite the company's sprawling design empire, and today is in charge of 2,500 people who have a hand in designing GM cars. "He nurtured a creative, inclusive, and customer-focused culture among our designers that has strengthened our global brands," Mary Barra, GM chairman and CEO, said in a statement." Welburn took the helm when GM and the industry were shaking off a general styling malaise that pervaded the 1980s and 1990s. During his 13 years in charge, he took risks, produced a wide range of styles for everything from hybrids to sports cars to big trucks, and leaves GM design in a better place. Welburn's replacement, Michael Simcoe from GM's international design unit, has big shoes to fill. News & Analysis News: Tesla attracted more than 325,000 preorders of the Model 3 in about a week. Analysis: If anything, the Model 3 is more popular than many expected. Elon Musk tweeted that surprising figure on Thursday, and he said just five percent ordered the maximum number of two. That seems to indicate actual owners rather than speculators are fueling the demand. With a starting price of $35,000 before incentives and an electric range of 215 miles, the Model 3 is the Tesla that's attainable for a lot of people. Clearly, that notion is resonating. News: Lincoln has drawn 40,000 hand-raisers for the Continental. Analysis: Okay, that's not a Tesla figure, but it's still an encouraging sign for Lincoln that one of its most famous and historic names still resonates in 2016. It also demonstrates using a real, albeit slightly dusty name, was the right call for the MKS replacement. "No other Lincoln vehicle has generated this much interest in this little time," Lincoln president Kumar Galhotra said in New York last month. The concept that debuted a year ago put Lincoln back on the map, and the production version remains true to that promise. It will stand out on the road when it arrives this fall, and ultimately, that kind of style will determine Lincoln's future.

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.

Koenigsegg sees new Tesla Roadster as the 'gauntlet' thrown down

Christian von Koenigsegg, the man behind the company that holds the current record for world's fastest car, does not like to be outdone. So he did not particularly enjoy hearing the numbers regarding the forthcoming next-generation Tesla Roadster and its vaunted 1.9-second 0-60 mph time. "We kind of had our future mapped out, and then we heard about the new Tesla Roadster and its insane acceleration numbers, and we thought 'Damn, that's put the gauntlet down,'" the Koenigsegg founder and CEO told Top Gear. As he told the site, he enlisted his engineers to start running numbers, and within a couple of days, they'd figured out a solution. "The simplest way of putting it is like this: It's combining direct drive with the hybridization we have in a different format with free-valve engine technology, in a peculiar layout," von Koenigsegg said. He said the powertrain could take a car from 0-250 mph in 14 seconds "or something like this," and said he wants to make a combustion engine with a higher power density than an electric powertrain "for as long as possible." His talk about hybrids brings to mind the Koenigsegg Regera plug-in hybrid, which weighs just 3,505 pounds and puts out more than 1,500 horsepower. It does 0-62 mph in 2.8 seconds — impressive, but a full 0.9 seconds less than the Roadster's purported time. And not surprising for a company that is all about maximizing ponies, Koenigsegg likes to geek out over the details of things like the design of the 1,160-hp Agera RS engine. Could he be talking about the same vehicle as the successor to the Agera RS, rumored to be called Ragnarok? Tesla, meanwhile, unveiled said Roadster at Grand Basel in Switzerland — or rather, it showed off what appeared to be a white, empty design shell that had been shown last year at Tesla's shareholder meeting. And don't forget that the mad scientists over at Hennessey are tinkering with the 7.6-liter V8 for the Venom F5, the key to its quest to hit 300 mph.
