CAR and Autoweek have tapped their sources within Volkswagen to get the scoop on a rumored mid-engine Elise-fighter that may debut at next month's LA Auto Show. But when working with unnamed insiders, information tends to get jumbled in the process and differing reports emerge that suggest it's all more speculation than hard facts.

Both reports confirm what we've heard before: Volkswagen will limit the cylinder count to four, but that's where the similarities end. Autoweek's sources say that engine choices will be limited to either a 170-hp 1.4-liter Twincharger TSI gasoline engine or a new 125-hp 1.6-liter TDI sending power to the rear wheels through a seven-speed dual-clutch gearbox. CAR pegs displacement of the gasoline engines at between 1.2- and 1.4-liters, with output ranging from 105 to 160 hp. A 1.2-liter TDI producing 75 hp is also being bandied around.

According to Autoweek, the mid-engine coupe will come to market in 2011, while CAR contends production won't begin until 2013. Additionally, CAR reports that VW won't use an aluminum architecture due to cost constraints, meaning that the Modular Sports Car (MSC) will come in at around 2,660 pounds (300kg heavier than the Elise). On the other hand, Autoweek is saying that the concept will tip the scales below 2,200 pounds by tapping Audi for its expertise with aluminum and opening the door to a four-ringed variant with a choice of a 211-hp 2.0-liter TFSI or a 204-hp twin-turbo'd 2.0-liter TDI. Not to mention the possibility of a Porsche 914 successor.

A strut-based suspension will be employed instead of a Golf-derived multi-link arrangement, while parts cribbed from the rest of the VW line – ranging from steering components and brakes to electronics and transmissions – will be used to keep manufacturing costs in check. Autoweek is also reporting that both a coupe and roadster will be offered, which strikes us as totally unnecessary as VW would be better served offering a removable hard-top similar to that on the MSC's target, the Lotus Elise.

Saying that "only a fool would ignore" the emissions of a new vehicle and the current global economy, AMG head-man Volker Mornhinweg realizes that it can't keep building gas-guzzling supercars with reckless abandon. Not that the company will lose its performance edge, mind you. In fact, hybrids and diesels could offer a meaningful performance boost if tuned properly. How so? Torque. Diesel engines are known for their massive axle-shreading twist, and electric motors, an essential part of any hybrid powertrain, make maximum power right off idle, allowing for an internal combustion engine that's tuned for stratospheric revs.

In a recent interview with CAR, the notion of fitting a twin-turbocharged 3.0-liter oil-burning V6 inside the C class was kicked around. Mornhinweg suggests such a vehicle is a distinct possibility as AMG moves forward. Hybrid technology could be based on the new drivetrain powering the recently-unveiled S400 BlueHYBRID. No matter what the future holds, we can be sure that the AMG crew is obviously not made up of a bunch of fools, and will therefore continue to offer cars with the highest performance pedigree, regardless of what's underhood.

The Mazda MX-5 is one of the world's best handling cars under $25,000, and as much as we Americans want more power and size to turn the Japanese roadster into a proper pony car, that's probably not going to happen. Increased fuel economy and CO2 reductions will force the MX-5 into the same situation as larger vehicles. It has to get more efficient and lighter to stay competitive. MX-5 program manager Takao Kijima told Drive that Mazda is looking at alternative powertrains for its little roadster, but the Zoom Zoom specialists are also looking to drop 10% of the car's weight.

One way to improve efficiency is with diesel technology. Diesels can be 30% more efficient than petrol powerplants, but beefier diesel parts means that total displacement must be smaller than the current engine's 2.0 liters. Another idea is a hybrid, which, like the diesel, would provide instant torque that would also add weight to a vehicle that's just about to go on a diet. Kijima also stated that any MX-5 would absolutely have to have 50/50 weight distribution, meaning that a hybrid with its heavy batteries would by tricky, but not impossible. For our money, we'll take a 10% lighter Miata with a smaller turbocharged, direct-inject gas engine with ethanol injections.

Car and Driver recently strapped its test gear to the new Chevrolet Corvette ZR1 and, as expected, recorded some impressive numbers. All eyes have been on the supercar Vette as it enters the boxing ring to duke it out with the heavy-hitting Dodge Viper SRT10 ACR, Nissan GT-R and Porsche GT2 (among others), and it looks like the latest Corvette will more than hold its own. According to C&D's trusty electronic gear, the supercharged 638-hp beast knocked off a 0-60 mph time of just 3.4 seconds as it continued towards a blistering 7.6 second 0-100 mph run. The quarter mile was cracked in 11.5 seconds @ 128 mph (Chevrolet claims 11.3 seconds, but the guys at C&D didn't believe in "...that sort of drivetrain abuse" to get lower numbers). The top speed also remains unverified as the team "ran out of room" before they could hit the claimed 205 mph. Under braking, the ZR1 set a new C&D record as it hauled itself down from 70 mph in just 142 feet. Of course, we must mention the obligatory claimed Nürburgring lap time of 7:26 (at the hands of Chevrolet). So you don't have to Google the competition's best-claimed Ring times yourself, here they are: Porsche GT2 - 7:32, Nissan GT-R - 7:29, and the Dodge Viper ACR - 7:22. Of course, we'd like to see all four on the track under identical conditions, and with some digital timing gear!

Fans of the classic B-Body Dodge Charger from the late '60s and early '70s have long been disappointed that Chrysler released the modern Charger as a four-door sedan. Despite being a sales success, there is still a faction of die-hard MOPAR fans who believe it was a mistake to put the Charger name badge on anything other than a two-door. We'll be polite and leave the '80's four-cylinder front-wheel-drive Charger out of the discussion – oops. A company by the name of Force Performance is currently working hard to rectify the situation by chopping up an LX-based Dodge Charger into a coupe. As you can see from the pictures in our gallery, the scalloped doors from the 68-70 Charger have made the conversion along with a twin-nostril split grille reminiscent of the classic '69. We can also see a well-domed hood, which is necessary for clearance over the insane HEMI V8 engine that's both twin turbocharged and supercharged. Three blowers, hence the TriCharger name. Awesome. Thanks for the tip, Orange Bread!

Nissan continues to parade around a 370Z prototype near the Nürburgring in Germany, and today our spy photogs have nabbed its interior during a refueling stop. As you can see, the interior is definitely a Nissan, and in facts looks Infiniti-esque thanks to the large nav screen and joystiq-controls dominating the center stack. The spies say the quality of materials appear to be a vast improvement over the current model, and you can see this particular prototype's interior is wearing bright orange suede door panel inserts and orange seats. Certainly livens things up, no? Elsewhere there are three gauges atop the dash that point towards the driver and big paddle shifters behind the steering wheel, which our sources suggest may indicate that Nissan will use a version of the GT-R's six-speed dual-clutch transmission. That may not be the case, however, as the current car's five-speed automatic with paddle shifters, which Infiniti already pairs with the company's 3.7L V6 in its G cars, would look the same from peering in through the car's windows. Check out more interior and exterior pics that we've added to our gallery of 370Z spy shots below.

In a recent post about the 2009 Dodge Challenger SE, KickingTires quotes director of Dodge brand marketing, Mike Accavitti, saying that there will be no convertible version of the reborn muscle car in Dodge showrooms. Apparently the platform would require too much additional hardware to handle the extra flex from cutting the roof off, and the added weight would push the car too far into the Sumo class. And that would be with just a simple manual soft-top, not one of them there new-fangled retractable hardtops that are the top du jour for convertible buyers. There's also the issue of cost and the fact that Dodge's market analysis seems to indicate there isn't a huge market for them. We understand the reasoning and know that even the coupes are going to be low-volume, but we would humbly like to suggest a limited run of SRT-8 convertibles at double the coupe's asking price. Say 20 or so. Buyers will pay twice the sticker price at least and mothball them immediately so they can be exhumed in 2050 and be the '71 Hemi 'Cuda convertible equivalents of their day.

Nissan's upcoming redesign of its Z car is almost here, and proof positive is this prototype caught cruising around in the vicinity of Germany's famed Nürburgring. The redesign is on full display here, with the boomerang-style headlights and taillights first seen on the new Maxima clearly visible. The whole front end is new but retains a visual connection with its predecessor, while big fender flares give away that the new car might be rolling on a wider track. There are also a few more kinks and creases on the new car, which are on display in the chunky C-pillar. We think it looks terrific as an attractive evolution of the current 350Z. The new car will change its nomenclature slightly to 370Z when it debuts this auto show season thank to the addition of Nissan's new 3.7L V6 that will be producing well over 300 horsepower in the new Z. Word has it that Nissan has also worked hard to address one of the biggest criticisms against the current car: weight. We'll probably have more spy shots of the 370Z as soon as Nissan begins running it around the 'Ring, and wouldn't be surprised to see the car officially debut at next month's LA Auto Show.

There are already a ton of Ford Mustang variants on the market, and Dodge has seen fit to offer three separate Challenger models, the SE, R/T and SRT8. Could Chevy do the same with the new fifth-gen Camaro? It's possible, though there's been no official word from General Motors as of yet. A Z28 model to join the base and SS trims would seem like the next logical step if the line were to be enlarged.

A talented designer who goes by Jinx on Camaro forums has created some renderings of what a Camaro Z28 could look like. He envisions a supercharged 6.2L LSA engine underhood with 550 horsepower. That hood would need a power bulge to cover the supercharged mill, and the rendering features a clear opening like the latest ZR1, along with a carbon fiber splitter up front. An enlarged lower air intake would feed the intercooler and is also flanked by functional brake cooling ducts. Quad exhaust tips give those spent gases plenty of room to exit. If a Z28 were to come from the General, they could certainly do worse than to use this guy's design. Check out more of his renderings in the gallery below.

The rumormill is a funny thing, and sometimes it can run amok. This appears to be one of those times. The DigitalCorvettes.com forum posted a note earlier this evening saying that Corvette ZR1 production has been halted (Bowling Green is shut down this week, so no Vettes are being built at the moment) and suggesting that the ZR1 may be cancelled. A post on dealer Rick "Corvette" Conti's blog, linked in the referenced DigitalCorvettes thread, added to the intrigue.

Autoblog has contacted GM's Terry Rhadigan, who handles global communications for the Chevrolet brand. We presented the DigitalCorvettes link and asked for an official response. His was very clear:

"Not true."
