We obsessively cover the auto industry…

In Autoblog's recent First Drive of the 2015 Challenger SRT with the 707-horsepower Hellcat V8 we found its engine to be as brutally powerful as the numbers would suggest, even if it wasn't the best handler. However, the muscle-car-styling just isn't right for some buyers that need four doors and proper rear seats to haul around the family. It appears that Dodge has their backs, though, because the Hellcat is very likely on its way into the Charger in the near future. Imagine the looks on your passengers' faces when you stomp down on the throttle.

According to Road and Track, when Dodge submitted the Hellcat for engine power certification to the Society of Automotive Engineers, the company included the Charger on the paperwork. That showed that the automaker wanted the engine checked out for the sedan, too. R&T reckons the 707-hp Charger would hit the road about a year from now, clearing the Challenger for a year of exclusivity with the powerplant.

When the Charger SRT Hellcat does hit the road, it may carry a very special accolade. Assuming nothing beats it in the meantime, it might be the world's highest horsepower production sedan. Think on that for a second. Even a Mercedes S65 AMG only has 621 horsepower, though a good bit more torque at 738 pound-feet to the Dodge's 650 lb-ft. So while the beastly engine is getting put into other models, where else would you like to see it? The Ram? Grand Cherokee? Let us know in Comments.

Sometimes important decisions come down to a split second where you just have to go with your gut. While leaving is son Paul's soccer game in the early 1990s, Ron Cressey spotted a 1959 Peerless GT on a car transporter. It turned out the owner was moving and shipping the car with him. Not wanting to let the opportunity pass, Ron started negotiating and bought the car on the spot. It took him another five years to restore it for vintage racing.

Cressey certainly has an eye for rarity because Peerless is among the lesser known British sports car builders. The company went out of business in 1960 and only sold cars for a few years. For the GT, Peerless took the engine, transmission and front suspension from a Triumph TR3, plus a Jaguar rear differential, and crafted a coupe body over it all.

As usual, Petrolicious contributes cinematography that is among the best anywhere on the web, and its sound mix allows the Peerless' four-cylinder engine to really sing. Scroll down to learn more about this vintage racer and the father/son connection that keeps it at the track.

We can lament the passing of the Mercedes-Benz M156 6.2-liter V8 until the end of time (and we probably will), but none of our moaning is going to stop Mercedes or the madmen of AMG from coming up with more modern, forced-induction mills like the 5.5-liter twin-turbo V8, or this, the company's new 4.0-liter twin-turbo V8. The freshly unveiled mill will make its production debut in the Mercedes-AMG GT, and based on the stats, it should prove a real honey.

Code-named M178, the new, turbocharged mill comes to party with 510 horsepower, but its big trick is the 479 pound-feet of torque it deploys between 1,750 and 4,750 rpm. Engine, thy name is usable power. The new 4.0 can rev to the same 7,200 rpm redline as the 6.2-liter V8 in the SLS AMG, meaning it should be a jolly good engine to wring out. The two turbochargers, meanwhile, can run to a maximum pressure of 17.4 psi and can spin to 186,000 rpm.

The measure of an engine isn't limited to just its power output. In today's world, it needs to be light. According to AMG, the new 4.0 is just that, boasting a dry weight of just 461 pounds, thanks to an aluminum crankcase. AMG even cast an eye on the way the engine's fat is distributed, fitting the turbochargers not outside the cylinder banks, like on a typical engine, but in what it calls the "hot inside V" configuration. That allows a lower, more compact engine package whose weight is better distributed.

Sound is arguably one of the AMG engine's most important aspects, and in that important arena, the 4.0 shouldn't disappoint. Slated to debut in the Mercedes-AMG GT, the 4.0 will be paired up with an exhaust that includes variable flaps that open and close depending on things like the transmission mode and throttle inputs. That should allow the GT's new engine to balance the AMG sound we know and love with a more relaxed, mellow and quieter character in everyday driving.

We'll have much more on both this engine and the car it will debut in, the Mercedes-AMG GT, in the coming months. Until then, there's a wealth of nitty gritty information available in the attached press release, from Mercedes-Benz. Scroll down for a look.

Faulty Takata airbag inflators keep taking their toll on automakers. Mazda is the latest to be affected in the US by announcing a recall covering 18,050 Mazda6 and RX-8 models to replace the front, passenger-side airbags. Specifically, the campaign covers 18,000 Mazda6 units from the 2003 and 2004 model years built between May 29, 2002, and March 4, 2004, and 50 RX-8 vehicles from the 2004 model year made between June 25, 2003, and June 30, 2003.

As with the rest of the vehicles with these faulty inflators, it's possible for the part to rupture when deploying the airbag and potentially spray shrapnel at the occupant. Mazda's defect notice goes into a bit more detail than most about the problem saying: "some propellant wafers have been produced with an inadequate compaction force, or may have been exposed to uncontrolled moisture conditions (those wafers could have absorbed moisture beyond the allowable limits)."

This isn't Mazda's first difficulty with Takata-supplied airbags this year. The company was among the seven automakers that recalled vehicles in hot-weather states over the inflators. It also had to recently fix 42,000 Mazda6 vehicles in China over the issue.

Repairs of the Mazda6 and RX-8 are scheduled to start in August, and obviously there's no charge to owners. Scroll down to read the recall announcement, or read the complete defect notice as a PDF, here.

The Nissan Cube is on its way out here in the US and Canada. In a way, that's too bad, simply because the Cube's styling was nothing if not distinctive – much like the company's own Juke. However, the flame for uniquely styled models is indeed still burning over at Nissan.

We might never see an exact replacement for the Cube in the brand's lineup, but product planning boss Andy Palmer says that its retirement leaves a spot open in the Nissan lineup for something else. "To be clear, we will morph this space in our portfolio into something iconic," said Palmer to Automotive News. Unfortunately, he wouldn't hint at what that could mean.

However, his lack of suggestions makes it fun to speculate about what oddity could replace the Cube, especially since two of Nissan's more recent quirky concepts might have problems hitting the road. The Bladeglider is mired in Nissan and Deltawing Technologies' ongoing patent lawsuit. Alternatively, the retro-inspired IDx might be too expensive to build profitably. Still, this is the company that created both the (nearly dead) Murano CrossCabriolet and the very successful Juke; it can probably come up with something else delightfully weird.

The Subaru WRX range is growing just a little bit larger, at least in Japan, with the automaker's teasing announcement of a new version called the S4. Unfortunately, the company is keeping details about its latest all-wheel drive sport sedan a closely guarded secret for the moment.

From what we can glean, it appears that the S4 might be a more luxurious take on the WRX. According to the release, the name stands for the four qualities that Subaru wants the sedan to have: "'Sports performance', 'Safety performance', 'Smart driving' and 'Sophisticated feel.'" As part of this focus, the car comes with the company's EyeSight camera system. Thankfully, we don't have too long to wait to find out what all of the buzz words actually mean because Subaru is unveiling the S4 on August 25 in Japan.

The automaker also launched a teaser website for the S4 that you can cheek out, here, but at the moment it doesn't provide any more details about the new sport sedan. The site just has countdown until the August reveal. There's also no indication yet whether this potentially more premium WRX could make it US shores. Scroll down to read the Subaru's rather concise teaser for the upcoming S4.

After a string of recent announcements from automakers, Kia may be the next business to break ground on a factory south of the border. The Korean company is reportedly nearly finished with negotiations to build a $1.5-billion plant near the city of Monterrey in the Mexican state of Nuevo Leon. The state's secretary of economic development confirmed the news to Reuters and anticipated talks to be completed in the first two weeks of August. Unnamed insiders also said that the location was aiming for an annual production capacity of 300,000 vehicles.

Rumors from a month ago first suggested the possibility of the new factory. It would reportedly build two models of small cars, and assembly could potentially begin as soon as 21 months after breaking ground. Currently, Kia only has one North American plant, in Georgia, that builds the Sorento and Optima.

In the last few years, Mexico has become of hotbed of North American automobile production. Mazda, Honda and Volkswagen all recently opened new or expanded factories to build cars there. There are even more on the way with a joint venture plant from Mercedes-Benz and Infiniti and BMW's announcement of its own $1 billion undertaking in Mexico.

Autoblog reached out to Kia for official confirmation of the Mexican factory, and the company emailed the following prepared statement to us:

"As one of the world's fastest growing automakers in recent years, Kia Motors Corporation is currently evaluating various options for the establishment of a new overseas manufacturing plant in order to secure future growth for the brand. As a part of these efforts, and to better cope with the ongoing supply shortage situation in the Americas region, Mexico is being considered as a possible location of our next overseas production facility."

Ask anyone who's anyone about Aston Martin and they'll tell you about exclusive and highly desirable two-door luxury GTs – the kind James Bond would drive – but it would be all too easy to forget about the other side of the equation. The company's full name is, after all, Aston Martin Lagonda Ltd., but while the latter name is seldom used, it's about to make a rare comeback.

The British automaker has just confirmed "strictly limited series production" of a new Lagonda saloon, previewed by the two teaser images you see here. The super sedan will be built in the same facility that previously produced the One-77 supercar at the Aston Martin factory in Gaydon and will be available in strictly limited quantities by invitation to select customers exclusively in the Middle East.

Aston Martin has revealed precious few technical details of the new project, but the design clearly pays tribute to the iconically wedge-shaped 1976 Aston Martin Lagonda sedan designed by William Towns, with elements from the recent Zagato-designed Centennial editions evident as well. It will be based on Aston's ubiquitous VH platform that underpins just about everything it currently makes, and given the proliferation of the company's long-serving 6.0-liter V12 engine, we figure it's safe to say that'll provide the motivation as well, with at least the same 565-horsepower output as the Vanquish and the new V12 Vantage S Roadster, if not more.

The announcement, of course, hardly comes as a surprise. Just a few months ago we spotted a disguised prototype for this very vehicle undergoing testing, and Aston has been toying with the idea of a Lagonda revival since the debut of the rather controversial Lagonda crossover concept at the 2009 Geneva Motor Show to mixed reviews. There was since talk of partnering with Mercedes-Benz to revive the Lagonda line along with Maybach, but that ultimately fell through – although the two are still collaborating in other areas, including the provision of a new line of engines and other technologies.

Lagonda was originally founded independently in 1906, was acquired by legendary Aston chief David Brown in 1947 and has popped on and off the radar screen ever since. It remains unclear whether the new sedan will revive the Lagonda handle as a nameplate or as a separate brand, but you can delve into the press release below to read what Aston has confirmed thus far.

Today, we have the Porsche 918 Spyder. Before that, there was the Carrera GT. While both of those cars are dramatic departures from the traditional, rear-engine Porsche formula, they owe their very existence to another wild child of the iconic German brand – the 959.

Like so many of the great performance cars of yesteryear, the 959 was a homologation special, built just so Porsche could go racing in the clinically insane Group B rally series. Fewer than 400 959s hit the streets, but those that did were some of the most advanced cars of the 1980s. A rear-mounted, twin-turbocharged flat-six sent its power through a still-rare all-wheel-drive system, creating a race-inspired rocket that was, for a short time, the fastest production car on the planet.

Xcar has the story of the 959, from its inception to its conquest of the Paris-Dakar rally, which is interspersed with a drive of the legendary coupe. Scroll down for the full video.

40+ gas guzzlers that aren't

The Gas Guzzler Tax affects many high-performance vehicles, but there are plenty of cars that straddle the line simply because their fuel economy ratings are slightly above the cut-off. Here, Seyth Miersma explains the tax in detail, and lists over 40 gas-guzzlers that manage to avoid this charge.





Review: 2014 Audi SQ5

Audi offers a delicious S4 Avant in other markets, for folks who want a fast, luxurious, people-and-cargo-hauler. But as associate editor Brandon Turkus explains, we Americans aren't totally left out in the cold with the absence of this S4 in our market. Audi's own SQ5 might be exactly what these customers are looking for.





Acura NSX burns at the 'Ring

Remember that Acura NSX prototype we saw running 'round the 'Ring the other day? Well, there's been a tragic turn of events. It appears the car we spotted earlier has gone up in flames, coming to a charred end while doing some further Nürburgring testing. Thankfully, nobody was hurt, and we've got a full gallery of the flame-broiled NSX, here.

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.

One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.

Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics – although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.

Nissan has been playing its cards pretty close to its chest when it comes to the production costs for Leaf battery packs. The company recently put a price on replacement batteries for customers at $5,500 plus the requirement to return the old battery. If the decommissioned battery is worth $1,000 to Nissan, as they have stated, that means the battery costs about $6,500 to make, right? Maybe even less if Nissan wants to turn a profit, as automakers are wont to do? Wrong.

Green Car Reports spoke to Nissan about these battery costs, and found that the automaker actually loses money on selling the replacement battery for the Leaf at the current price. Jeff Kuhlman, Nissan's vice president of global communications said, "Nissan makes zero margin on the replacement program. In fact, we subvent every exchange." All you English majors will know that "subvent" is a fancy way to say "subsidize." Kuhlman added, though, "We have yet to sell one battery as part of the program."

The fact that Nissan offers its replacement batteries for less than it costs to manufacture them is telling of a company both cares about what its customer needs and is dedicated to the success of its product. In this case, both of those things encourage people to give up fossil fuels and adopt electric mobility, which is heartening. As more people switch to battery-powered driving, though, battery technology should become better and cheaper, and the scale of production should cause manufacturing costs to decrease. Eventually, Nissan could easily see itself breaking even selling the Leaf battery replacements.

Nissan Leaf replacement battery is covered under the same eight-year, 100,000-mile warranty as the battery in a new car.

Imagine the King of Rock n' Roll driving a car and you'll likely picture a pink Cadillac or a yellow De Tomaso shot full of holes. But Elvis also owned a 1957 BMW 507 roadster, and now that roadster is returning home to BMW headquarters.

The 507 was a rare bird, of which only 254 examples were ever made. They were sold mostly to celebrities and royalty, but Elvis Presley was a GI when he bought it while stationed in Germany. The example that he bought had been displayed at the Frankfurt Motor Show, used as a press car and raced by Hans Stuck (which is how Elvis came to see it in the first place), so when he took delivery of it second-hand, the dealership had a new engine installed. It was originally white, but legend has it that Elvis got tired of women writing their phone numbers on the side of it in lipstick that he had it repainted in red.

Stories differ on what exactly happened to it next, with some saying that he returned it once the lease was up and other saying that the army shipped it back to him in the States after his tour was over. But what we do know is that the car sat for many years, neglected but sheltered from the elements. Now it's heading to the the BMW Museum in Munich, where it will be on display until August 10, after which the BMW Group Classic department will undertake a comprehensive restoration of the star-studded roadster that's expected to take two years of work.

While its days may be numbered, Ford isn't just going to let its Falcon sedan limp out for the Australian market. No, the Blue Oval is releasing a refreshed Falcon for its final years, and it's lead by this, the new XR8. That's right, this dead-car-driving is going to go out on a high note.

Ford's global design DNA dominates the looks of the new Falcon, with a grille reminiscent of the US market Fusion and the European-market Mondeo. The headlights aren't a straight port, and boast their own unique LED running light pattern (at least on the XR8), but the overall look is strikingly similar. Out back, LED taillights highlight the rear of the Faclon. Despite the substantial new fascia, this is still a mid-cycle refresh. That means most of the rest of the Falcon's body panels are carryovers from the current model.

The XR8 model, shown above, arrives with a supercharged V8, allegedly displacing 5.0 liters. Unfortunately, details on the Falcon's mechanicals are in remarkably short supply. Ford has committed to a range of turbocharged four, as well as turbocharged and naturally aspirated six-cylinders, in addition to the V8, although specifics on those mills aren't available.

It isn't just information that's in short supply ­– official images of the new Falcon are limited to the pic you see above. Of course, we're working on getting more of both, and as soon as that happens, we'll be sure to update this post. Scroll down for the brief, styling-focused press release from Ford.
