We obsessively cover the auto industry…

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.

While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity – besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan. Scroll down for the official press releases from Chevrolet and GMC.

Behold the 2014 Aston Martin Vanquish Volante in all its convertible glory. Like its hard top twin, the convertible Vanquish boasts a 5.9-liter V12 engine with 565 horsepower and 457 pound-feet of torque. That thrust is good enough to push the car to a top speed of 183 miles per hour, and Aston Martin says the 2014 Vanquish Volante is the first of the company's convertibles to bow with body panels comprised entirely of carbon fiber. It also offers the stiffest body structure in the history of the automaker's droptop efforts.

The machine's power three-layer top can be put up or down at speeds of up to 30 mph and can do its dance in around 14 seconds. Interestingly, designers went with a full-length windshield, which runs directly up to the cloth top. there is no sheetmetal (or in this case, carbon fiber) header between the glass and the roof. Very cool.

A six-speed automatic transmission handles shifting duties and a new set of springs and dampers help cope with altered dynamics of the convertible. Aston Martin claims the 2014 Vanquish Volante offers up a weight distribution of 51:49, and a set of carbon-ceramic brakes help bring the whole party down from speed. If you want one, get ready to shell out at least $297,995 for the pleasure. Deliveries are set to begin early next year. Check out the full press release below once you stop gawking at the gallery above.

While its dealer body has been clamoring for new and larger models, Fiat has actually done a pretty good trade selling all manner of 500 variants, from the standard hatchback and 500C cabriolet to its Abarth models, 500e electric runabout and special editions like the Gucci.

Fiat USA was a little slow out of the gates as it built up brand awareness and its dealer network, but it's now chugging along, with combined 500 model sales outselling that of its arch rival Mini (provided you subtract the Countryman crossover, a model for which Fiat has had no direct competitor up until this point). Franchisees are finally about to get the bigger, broader-appeal model they've been seeking in the form of the five-door 500L, but Fiat is still going to be devoting a lot of attention to their whisker-faced icon, the Cinquecento.

As proof, at the first drive event of the 500L in Baltimore, Fiat North America boss Jason Stoicevich confirmed that his company will produce a production version of the 500 Cattiva concept shown at the Detroit Auto Show in January. Stoicevich wouldn't divulge the model's pricepoint or availability timeframe, but he told us, "I can guarantee you it will happen. I just can't tell you when."

The Cattiva is based on the middle-child 500 Turbo, and is essentially a trim-and-tape package, albeit a very attractive one. It includes rich 'Rame' (read: copper) paint with black trim, including 'Nero' gloss black light housings front and rear and a matching roof-mounted spoiler along with unique charcoal 16-inch alloys. Inside, changes are limited to a 'Matte Nero' instrument panel and trim, along with silver stitching on the black sport wheel and shift knob. No word on any improvements to the Turbo's 135-horsepower, 1.4-liter MultiAir four-cylinder, but at least that should keep the price from rising much above the standard 500T's $19,500 MSRP. As far as timing goes, we're thinking that this model won't be too far down the line after the company launches the 500L.

Back when it revealed the 500 Cattiva concept, Fiat also showed a matte gray Tenebra showcar that builds upon the even hotter 500 Abarth, but Stoichevich declined to comment on that concept's chances for production.

The Detroit News is reporting that the National Highway Traffic Safety Administration has opened an investigation on the 2006-11 Suzuki Grand Vitara and 2007-11 Suzuki SX4 due to issues with the airbag and seatbelt for the front passenger seat. So far, NHTSA has received 128 complaints on these vehicles for airbag warning lights, airbag off lights and seatbelt lights, on a vehicle set that totals around 205,000 units, but there is no indication as to how many, if any, injuries have reported.

Via technical service bulletins, Suzuki has already acknowledged two airbag-related issues with front passenger seats on both vehicles, including a programming error for the passenger seat load indicator on 2009 models and an open-circuit problem for the sensor mat that determines if an adult or child is sitting in the front seat. Since this latter issue would not shut off or lessen the impact of the passenger airbag, Suzuki has already extended the warranty for the seat cushion bottom to 10 years or 120,000 miles. After ceasing new-car sales in the US and Canada, potential recall repairs (which still may or may not happen) would be handled by remaining dealers as laid out in the recent court-approved bankruptcy plan.

Combining moving visuals – slow-motion camera shots, impossible angles, beautiful scenery and, of course, ridiculously fast rally cars – with compelling storylines is a sure-fire way to win some friends in the Autoblog offices. And that's exactly what the video you'll see below has to offer.

As a teaser for a full-length documentary called Easier Said Than Done that's slated to be released on September 28th (internet release coming on October 1st), this video succeeds in whetting our appetites for the rest of the show – promising footage shot in eight countries over a period of 18 months – while leaving enough to the imagination that our ridiculously short attention spans aren't left too far behind.

Check out the video below, then set a reminder in your calendar for the end of September to watch the rest.

Lego has announced that the Mars Rover Curiosity will become the Danish company's next user-designed Cuusoo set to reach store shelves. The company's Cuusoo program allows anyone to submit an idea for a Lego set that could make it to production. After having been among a small group of sets to receive at least 10,000 votes – the minimum required – in the 2012 Fall Review on the Lego Cuusoo site, the Mars Rover Curiosity then survived an exhaustive review process, which not all sets do (sorry, UCS Sandcrawler), before receiving final approval from the company. While it got the nod, pricing and availability is yet to be determined as the set continues being developed for mass production. Scroll down to watch Lego make the announcement on video.

The Mars Rover Curiosity Lego set actually has an interesting back story. Its designer, listed as Perijove on the set's official Cuusoo page, is a mechanical engineer who worked on the real Mars Rover Curiosity at the Jet Propulsion Laboratory, which means his recreation of the rover is highly accurate, not only in how it looks, but also in the details and all of its moving parts. Perijove states that the purpose of his model is "to continue the educational outreach for this incredible mission." The timing couldn't have been better, as the set became popular on the Lego Cuusoo site in late Summer 2012 when the real Curiosity rover touched down and began rolling around on the surface of Mars.

The last set to make it all of the way through Lego's Cuusoo program was the Lego Back to the Future DeLorean, which received approval for production last December. Other autos-related Cuusoo sets that received 10,000+ votes and are scheduled for production review include an incredibly detailed Land Rover Defender 110 and minifig-scale Batman Tumblr.

Detroit's Big Three could become the Big Two. According to an AP report in The Detroit News, state officials have been lobbying for Fiat-Chrysler CEO Sergio Marchionne to select Tennessee as the location for Fiat's joint headquarters with Chrysler Group LLC.

This weekend, Marchionne met with Tennessee governor Bill Haslam at a ceremony celebrating the expansion of a Fiat subsidiary plant in the city of Pulaski. The AP report does not mention any serious talks about headquarters relocation, only that Tennessee officials have been "working me over pretty well," according to Marchionne.

Fiat hopes to complete its merger with the Auburn Hills-based automaker sometime next year, and earlier reports have stated that the company is seeking $10 billion in financing to buy the remaining bits of Chrysler. If the company were to relocate, it would join Nissan and Volkswagen in having major American automotive operations in Tennessee. Of course, that whole "Imported From Detroit" thing would need to go out the window...

Volkswagen has officially built 30 million Golf units since the first hatch rolled off the assembly line in early 1974. The company says the accomplishment has cemented the compact's place as the most successful European car ever built, though we imagine the original Beetle might have something to say about that. Even so, Volkswagen says that statistically speaking, the company has sold 2,000 Golf units for every day of production. Chew on that notion for a moment. The Golf has remained relevant over the past four decades thanks to a steady stream of generational updates, and last year, the Volkswagen Golf took the honor of being named the World Car of the Year.

A Golf TDI was the 30 millionth unit produced, and Volkswagen says the machine will be on display at the automaker's Wolfsburg facility. You can read the full press release below for more information, including a generational breakdown of each Golf model.

While mobile navigation for cars has evolved into a staple, in-cabin feature, motorcyclists have been stuck with paper maps and aftermarket solutions for years. A new Russian company is out to change that with a helmet that boasts integrated nav. LiveMap uses a microphone, light sensor, ear phone and micro display to convey pertinent travel information in full color that the rider can control using voice commands. The system works just like the heads up display found in modern fighter jets.

The system projects directions in the center of the rider's visor rather than in the upper right hand corner as with Google Glass. The team behind the development says this actually safer since the light sensor keeps the directions transparent no matter what the time of day. It also allows the rider to stay focused on what's ahead of the bike. An integrated gyroscope and digital compass keeps the projection oriented correctly even as the user tilts his head or leans the bike. Very cool.

The LiveMap helmet is supposed to offer up to a day's worth of use thanks to a pair of lithium-ion batteries, though a USB charge plug can provide extra juice when necessary. Right now, LiveMap is sourcing funding through Indiegogo. The company is looking to raise $150,000 to create a working prototype. After that, production models could cost around $2,000. That's steep, but hopefully the cost could come down over additional generations. Check out the introductory video below for more information.

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."

At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.

As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.

As Fiat prepares to expand the lineup of the 500 with the roomier 500L, the Italian automaker has just announced a further addition to its enlarged hatchback offering. While the standard 500L has a five-passenger seating configuration, the new 500L Living brings a third row of seats, upping capacity to seven passengers.

Based on the specs Fiat released, the 500L Living has had its overall length stretched by about eight inches to accommodate the extra seats, while width and height stay about the same. We still have no word on the wheelbase of this new model versus the 500L. Fiat also says that the 500L Living will have a luggage capacity of 22.5 cubic feet (we assume that number is with the rear seats folded, which is smaller than that of the five-passenger 500L (12.1 cu-ft with rear seats up and 46.2 cu-ft with rear seats down).

European sales of the 500L Living will commence this summer, but there is no mention as to if or when this seven-passenger Fiat could be offered in the US, to compete against the likes of the Mazda5, Ford Transit Connect Wagon and Nissan NV200. Scroll down for the more information on this new Fiat model.

So then we asked, "Well, what does that mean?"

We met Andreas Sigl, the global director of Infiniti's Formula One involvement (that's him above on the right), at the US Grand Prix in Austin last year, and our questions to him were aimed at understanding what Infiniti was doing and where it intended to go. In spite of regard for its products and increased sales, few outside – and even inside – Infiniti seemed to have a clear idea of what the brand stood for.

Its F1 partnership with Red Bull Racing was a key example of that. A brand with no motorsports pedigree – save for a listless dalliance with Indycar and the Infiniti Pro Series – was suddenly married to the world's marquee racing series, but one being continually declined by other brands and even its own entrants for a lack of relevance to road cars. The introduction of the Infiniti FX Vettel Edition didn't clarify matters; we still didn't understand how Infiniti logos on Adrian Newey's chassis' made the G, M, FX, et al any better – or who was even supposed to make the connection – and if we were exceedingly cynical we could have said the terrifically expensive Sebastian Vettel-fettled FX mutant was a marketing mission that needed a hand grenade but instead got a high-impulse thermobaric weapon.

Seven months after that Austin Q&A with Sigl, during which time Infiniti has become title sponsor of Red Bull Racing and publicly anointed Sebastian Vettel its Director of Performance, we met Sigl again in Montreal during the Canadian F1 Grand Prix. It was there we got an answer to what Infiniti stands for: "We've boiled the brand down to the four 'p's," he said. "Performance, passion, precision and provocation."

So then we asked, "Well, what does that mean?", and Sigl gave us some background on what's been happening behind the scenes of the partnership.

Buick first showed the facelifted 2014 LaCrosse at this year's New York Auto Show, and General Motors' luxury-ish arm has now confirmed that pricing for the updated sedan will start at $34,060 (*including $925 for destination), a increase of $1,505 over the 2013 model.

Buyers will be treated to an updated appearance, both inside and out. On the outside, tweaks were made to the LaCrosse's front and rear fascias, and new wheels are on offer (though the ones seen on the car pictured above seem to have been simply pulled from the 2011 Regal Turbo). Inside, there's a much cleaner center stack layout, complete with a standard eight-inch reconfigurable touchscreen IntelliLink interface. Buick is also offering a new Ultra Luxury interior package ($2,495), featuring Tamo Ash wood throughout the cabin, black synthetic suede on the headliner and leather seats in a new sangria color. Standalone options include different wheels, Bose audio, rear seat entertainment, navigation and a sunroof.

The 2014 LaCrosse's base powertrain is the trusty 2.4-liter four-cylinder engine with eAssist, which is capable of achieving up to 36 miles per gallon on the highway. But for folks wanting more power, a 304-horsepower, 3.6-liter V6 is available as a no-cost option, available with either front- or all-wheel drive.
