Brabus claims the world’s fastest, most powerful sedan with new SV12 R Biturbo 800

Mercedes-Benz is no stranger to wickedly powerful and insanely fast luxury sedans. After all, its AMG models are among the fastest and most powerful on the market. Leave it to specialty Benz tuner Brabus, then, to take it the extra mile… and then some.

The freshly unveiled Brabus SV12 R Biturbo 800 claims the mantle as both the fastest and most powerful sedan on offer. To get there, the German tuner has tweaked the 5.5-liter V12 from the S600 to 6.3 liters, fitted a new crankshaft, camshafts, cylinder heads, air intake, exhaust, turbochargers, quad interoolers and bigger pistons, and of course, remapped the ECU. The result is a massive 788 horsepower (800 in metric form, hence the name) and 1,047 pound-feet of torque. The twist is so massive, however, that Brabus had to electronically limit it to 811 lb-ft. Don’t worry – performance hasn’t been hindered. 0 to 62 sprints are managed in just 3.9 seconds and its Autobahn-devouring top speed is electronically limited to just 217 miles per hour.

Bigger brakes help keep the beast under control, as well as a new limited-slip differential. A full aero kit and upgraded rolling stock are on hand, as well, completing the “we mean business” look. Check it out for yourself in the gallery below, and hit the jump for Brabus’ official release.

Report: Washington to require that ‘quiet’ cars get alert sounds

Hands down, one of the few pleasures of driving a hybrid is cruising around in all-electric mode. There’s just something that’s undeniably cool about silently whisking along, but if a new auto safety bill makes its way into law, we can kiss even that one pleasure goodbye. A coalition of automotive manufacturers and advocacy groups for the blind have joined forces to make sure that silent-running vehicles will make more noise in the future. The logic is that the blind and other pedestrians are at risk of being struck by quiet hybrids and EVs. We can’t really argue with that one.

If passed, the bill would have the National Highway Transportation Safety Administration propose regulations for an “alert sound” within a year and a half, and finalize the rules within three years. Drivers would not be able to turn off the noise. So far, there’s no word as to how loud the noise would be or what it will sound like, but the technology already exists to make that sound signature variable – concept cars like the Brabus Smart High Voltage EV shown above can simulate the sound of everything from a buzzing bee to a good ol’ American V8 with hidden speakers inside and outside of the vehicle, with the sound varying according to engine speed. If we absolutely have to be making a racket while we drive on all-electric power, we vote for sounding like George Jetson’s daily commuter, but we’re not exactly crazy about user-selectable EV ‘ringtones,’ lest one’s daily commute become an auditory assalt of Star Wars Tie Fighters and clydesdales.

Infiniti FX50 S Dressed Up in Styling Package by Brabus' CRD Division

Here’s a proposal from this year’s Frankfurt Show that somehow managed to escape our radar. Supposedly a concept study, the Infiniti FX50 S Limited Edition was created by Car Research and Development or CRD for short, a subsidiary of the Brabus Group that works directly with automakers and their national importers. Among other cars, CRD was responsible (…) for the creation of the Dodge Avenger-based Startech Starster that appeared at the 2007 Frankfurt Show.

The Infiniti FX50 S Limited Edition show car gets a set of bespoke 21-inch turbine-design light-alloy wheels in a grey finish, while the front grille, side air inlets in the front fenders and the roof bars are also painted grey.

The luxury SUV’s cabin is upholstered in high-quality leather with contrasting light brown stitching while the carbon-fiber trim in a dark brown finish and the alcantara trim on the headliner and pillars round off the interior upgrades.

And yes, we too are wondering why Brabus / CRD even bothered to call this creation a concept study…

Report: Dodge version of Alfa Giulietta coming for 2012

According to the latest reports, the Alfa Romeo Giulietta will serve as the basis for the Dodge Caliber’ssuccessor, and it’s set to arrive in late 2011 as a 2012 model. USA Today credits Sergio Marchionne, CEO of Chrysler and Fiat, with the proclamation that some form of Giulietta will wind up as a Dodge. Considering last year’s five-year plan that shows the Caliber discontinued after 2011, Chrysler will need something to fill its place in showrooms.

Refreshes will carry the venerable LX cars, and the Sebring has been transformed into the more promising200, but those moves are mere stopgaps. Without a small car to sell against its domestic rivals, Chryslerand Dodge will be at a significant disadvantage. Fiat has expressed its desire to expand its stake in Chrysler beyond its 20 percent level, and the only way that’s going to happen is if the automaker succeeds Stateside. Enthusiasts have looked longingly across the Atlantic at the Giulietta, and if the car connects as well with the public at large and carries the right blend of quality and verve, it could be a boon for Chrysler.

Alfa Romeo Giulietta G430 iMove Marangoni debuts in Bologna

Think of Alfa Romeo and the color you’ll likely be picturing is red. But a custom version of the Giuliettaunveiled at the Bologna Motor Show has gone a decidedly greener route.

Outfitted by Italian rubber company Marangoni and fashion house Conte of Florence, the Giulietta G430 iMove is based on the Giuletta 1750 Quadrifoglio Verde and distinguished by special green tires riding on 19-inch Barracuda Karizzma alloys. But that’s only the tip of the proverbial iceberg when it comes to the modifications carried out on the special Giulietta.

A Ragazzon stainless steel exhaust system boosts output up to 232 horsepower, while a Tarox braking system, KW suspension and custom aero kit also factor in to the program, along with a golf-themed leather, Alcantara and carbon fiber interior by Conte of Florence. There’s even a Segway scooter mounted in the back, and you can get all the details about the show car in the press release after the jump and view it in detail in the high-resolution image mega-gallery below.

Is the next Dodge Viper really just a reskinned Alfa 8C?

Snakes are known to regularly shed their skin to reveal a shimmering new coat underneath. Doing it the other way around would be a unique trick, but if the latest reports are to be believed, that might be what we’re looking at.

Last week at a dealers’ conference, Fiat/Chrysler chief Sergio Marchionne reportedly pulled the covers off a new-generation Dodge Viper. With the current model having already been axed, our interest was, to say the least, piqued by this development. New reports emanating from the exclusive preview have given us cause for a little more consternation, however.

According to AutoWeek, the new Viper – expected to arrive sometime late next year as a 2012 model – looked eerily like an Alfa Romeo 8C Competizione with a more Dodge-like front end. That would be a shame, since the Alfa’s styling is its biggest asset; its chassis and performance dynamics, less so. Giving the 8C – based, as it is, on age-old Maserati architecture – a new shell and calling it a Viper strikes us as all kinds of wrong. Then again, like a great many rumors in the autosphere, this could all be mere conjecture.

Monterey 2010: Alfa Romeo centenary celebrated con brio

The year 2010 marks the 100th birthday of Alfa Romeo, the great Italian automaker that has given us some of the most lust-worthy road and race cars of, well, the last century. It was fitting, therefore, that Concorso Italiano celebrated the occasion with gusto. They even let the Alfas spell out the annual message to the heavens: a simple “100.” It would have been interesting to see them try to use 100 cars to do so; goodness knows there were at least that many Alfas on hand.

Check out the gallery and you’ll see a small sampling of the great variety of Alfas on display. As much as we like the new 8C Competizione, we have to say our favorite Alfa Romeo at Concorso was probably John Shirley’s 1938 Alfa Romeo 8C 2900B. Just take a look at that rear!

Report: Alfa Romeo Giulia sedan to launch next year?

With the new Giulietta now out in the open, Alfa Romeo’s attention is turning to its big brother. Set to replace the 159 sometime next year, the highly-anticipated nuova Giulia promises to improve on the outgoing sedan’s lackluster driving dynamics.

Based on Alfa’s variable C/D platform, the Giulia is tipped to get a McPherson front suspension with a twin-link rear setup. As with the Alfa 159, the Giulia is expected to be front-drive, with the trick Q4 all-wheel-drive system available as an option, hooked up to a variety of turbodiesel and MultiAir gasoline engines.

Unlike the MiTo and Giulietta, both of which are hatchback-only, the Giulia promises both four-door sedan and five-door wagons as part of the mix. The tantalizing end of the range, however, is tipped to include an in-house GTA model – with at least 300 horsepower, all-wheel drive and seven-speed dual-clutch transmission – and a lightweight, front-drive version with 350 horsepower to be co-developed with famed Alfa tuner Autodelta.

Alfa Romeo Announces UK Pricing for 2010 MiTo with New MultiAir Turbo Engines

Buyers in Britain will be able to order the 2010MY Alfa Romeo MiTo with new turbocharged petrol engines featuring the Fiat Group’s revolutionary MultiAir technology from early January with first deliveries expected in Spring. At launch, two engine versions will become available, 1.4-liter Turbo with 135bhp that’s priced from £15,165 (about USD$24,600), and the range-topping 1.4-liter Turbo Cloverleaf (Quadrifoglio) with 170bhp and a starting price of £17,895 (around USD$29,000).

The Fiat Group’s new MultiAir system directly controls the air and combustion in engines cylinder by cylinder, stroke by stroke, through the intake engine valves without using the throttle.

According to the Italian carmaker, the use of this technology results in a 10% reduction of CO2 emissions and fuel consumption, and a 10% engine power increase as well as a 15% torque improvement over an engine without this system.

New Alfa Romeo Giulietta with up to 235HP: First Official Photos [Updated]

*Update: Alfa Romeo has officially announced that the car’s name is ‘Giulietta’

After an bevy of factory spy shots and more recently, a squabble with the current and former employees of the Italian firm’s Milan plant that led to a last minute decision to drop the ‘Milano’ name, Alfa Romeo has finally published the first official image of its new compact hatchback that will replace the 147 and compete in the all-important C-segment in Europe.

Even though there have been rumors about the use of the ‘Giulietta’ name, the Italians have yet to announce something official.

However, there’s still some time left to choose a name as the compact hatch won’t be fully revealed until the Geneva Motor Show in March 2010.

The 147′s replacement, which will be made only as a five-door model, is based on the Fiat Group’s new C-Evo platform that will also be used in future Chrysler and Dodge products.

Measuring in at 4,350mm in length, 1,460 mm in height and 1,800 mm in width, with a wheelbase of 2,630mm, the new compact hatch is slightly longer, taller and wider than the current 147. It also features a boot capacity of 350 liters.

When it arrives in Alfa’s showrooms in spring next year, the hatch will initially be offered with a choice of two petrol and two diesel engines, all turbocharged.

The range will include the 1.4-liter TB and 1.4-liter TB Multiair petrol units with 120HP and 170HP respectively, and the 1.6-liter JTDM and 2.0-liter JTDM diesels with 105HP and 170HP respectively.

Later in the year, Alfa Romeo will introduce a sportier version wearing the “Quadrifoglio Verde” (four-leaf clover) badge to compete against the VW Golf GTI and Renault Megane RS. The QV will be powered by a 1.7-liter (1,750cc) four-cylinder turbocharged petrol engine delivering an output of 235 horsepower.
