What's in a trademark? Sometimes, the next iconic car name

The United States Patent and Trademark Office is a treasure trove for auto enthusiasts, especially those who double as conspiracy theorists.
Why has Toyota applied to trademark "Supra," the name of one of its legendary sports cars, even though it hasn't sold one in the United States in 16 years? Why would General Motors continue to register "Chevelle" long after one of the most famous American muscle cars hit the end of the road? And what could Chrysler possibly do with the rights to "313," the area code for Detroit?

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

Next Opel Insignia to adopt sleeker looks

The very first set of spy photos of the next-generation Opel Insignia have dropped, giving us a look at the more svelte, aggressive, and stylish look of the popular sedan. As a reminder, the Insignia is sold here in the United States as the Buick Regal. There's only so much we can discern from these photos, thanks to the very heavy camouflage. But we can get a look at the new Audi A7-like roofline, which our spies citing similarities to the Opel Monza concept car from the 2013 Frankfurt Motor Show. The Monza link fits with our previous reports, which claimed the gullwinged wagon would serve as a prime source of inspiration for both the Insignia and US-market Regal. Aside from the significantly redesigned sheetmetal, Opel is also increasing the size of its flagship sedan, adding nearly four inches between the axles. According to our spies, the goal is to build a vehicle comparable in size to the Skoda Superb, a roughly Volkswagen Passat-sized sedan based on the VW Group's MQB platform. What's most interesting for US customers, though, is the body style shown here. Like the aforementioned A7, the next Insignia will be offered as a five-door model, rather than a traditional sedan. The five-door hatch would later be joined by a traditional wagon. It's unclear whether the US market Buick will take a similar route, or whether General Motors will demand a four-door variant exclusive to North America. Check out the spy photos above, and keep an eye open for more on the next Insignia/Regal. Don't plan on seeing it at an auto show any time soon, though. It's not slated to debut until the 2017 Frankfurt Motor Show.
