A stretched Audi R8 is set to become the world’s fastest limousine.

Limo Broker in the U.K. recently announced plans to build the world’s first Audi R8 V10 stretch limousine.

The street-legal version of the Audi R8 will feature a massive V10 engine that powers the car from 0-62mph in just 3.9 seconds.

The V10 produces 500 horsepower and a top speed of 197mph.

The Audi R8 limousine is set to easily break the current 0-60mph limo speed record of 6 seconds held by a Ferrari limousine.

The Audi R8 limousine will comfortably fit eight people, and is expected to the hit road by summer 2012.

Limo Broker has not yet revealed the cost of the world’s fastest limousine, but we can assume it’s going to be considerably more than the standard Audi R8 V10’s $149,000 price tag.

Porsche only revealed their new 911 Cabriolet at the 2012 Detroit Motor Show earlier this week, but the carmaker has already unveiled another convertible: the new 2012 Porsche Boxster.

Porsche has described the 2012 Porsche Boxster as faster, lighter, cleaner, more economical, and better looking than its predecessor, and said it will be officially revealed at the Geneva Motor Show in March, before going on sale in the UK on 28 April 2012.

It will come with a choice of smaller 2.7-litre (265bhp) and same size 3.4-litre (315bhp) flat six engines and will cost £37,589 and £45,384 respectively.

When compared to its predecessor, the new 2012 Porsche Boxster has a longer wheelbase, widened track and bigger wheels (18-inch on the Boxster, 19-inch on the Boxster S).

The 2012 Porsche Boxster’s shorter front and rear overhangs and more steeply raked windscreen create a streamlined profile. As with previous models, the roof is made from fabric, but it now sits exposed behind the cockpit when its lowered.

There’s also been improvement in the performance department too. The Porsche 2012 Boxster accelerates from 0-62mph in 5.7 seconds – a tenth of a second faster than its predecessor, while the Boxster S takes exactly five seconds – an improvement of two tenths.

A six-speed manual gearbox is fitted as standard, but if you want to extract maximum performance and the best possible fuel economy, the optional seven-speed PDK gearbox is required.

Standard kit on the Boxster includes an Alcantara interior, remote control hood operation and a seven-inch touchscreen. The Boxster S adds partial leather and Xenon headlights to that.

The LA Auto Show provides an essential stage for carmakers to show off their latest models, since California is by far the largest car market in the U.S.

At the 2011 LA Auto Show, held last month, a host of new models and concept cars made their world debuts. Here are some of the most notable cars that made their debut at the 2011 LA Auto Show:

Cadillac XTS

General Motors Co.’s luxury brand unveiled the replacement for its old land yachts, the DTS and STS. The company promises space and elegance with technology for a new generation of buyers. It looks like a larger, rounded version of the CTS, and is powered by a 300 horsepower, 3.6-liter V-6 engine. The all-wheel-drive sedan will hit showrooms in the Northern spring.

Chevrolet Camaro ZL1 Convertible

The convertible version of the fastest Camaro ever. It’s due out this Northern summer as a 2013 model. The ZL1 sports car has a 550-horsepower, 6.2-litre supercharged V-8 and recently hit 170 miles per hour on a German test track.

Fiat 500 Abarth

Italian automaker Fiat SpA rolls out a high performance version of the round and cute 500 mini car. The car, which seats four, is more aggressive looking and its turbocharged 1.4-litre engine cranks out 160 horsepower, 59 more than the base version of the car. It has aluminum racing wheels, a heavy-duty five-speed manual transmission, a spoiler and a racing stripe at the bottom of the door. The Abarth is due to be released in the first half of 2012.

Honda CR-V

Honda unveils a new version of its five-seat crossover, which is one of the most popular vehicles in a fast-growing segment. This is the CR-V’s first update in four years. Expect modest updates to styling and power that should help keep the vehicle competitive.

Honda Fit Electric

The electric version of the Fit subcompact, which was shown as a concept car at last year’s Los Angeles Auto Show, is expected to go around 100 miles in a charge. It goes on sale in the U.S. next year.

Hyundai Azera

The Korean automaker rolls out a new version of its larger midsize car with a sleek body design and side creases. It comes standard with a 3.3-litre six-cylinder engine with gasoline injected directly into the cylinders for higher efficiency. Hyundai claims it will have best in class combined city-highway fuel economy of 23 mpg.

Infiniti JX

Infiniti launches an all-new seven-passenger crossover with an exclusive new feature: A system that automatically engages the brakes if the driver is about to back into something crossing behind the vehicle.

Subaru BRZ

The automaker famous for rugged all-wheel-drive cars and small SUVs enters the sports car market with the rear-wheel-drive BRZ sports car. Subaru is showing off a concept that will look a lot like a BRZ slated for production in the spring of 2012. It’s sleek and low with an aerodynamic front spoiler and a rear wing. The BRZ will have a new direct-injected 2-litre Subaru Boxer engine.

A retired couple managed to get their prized 1956 Bristol 405 Drophead Coupe through a world trip unscathed, but it was a trip to their local Sainsbury’s car park that ultimately put a dent in their classic car.

Geoffrey and Hilary Herdman took 16 months to complete the trip that they described as a “wrinkly gap year” in their 1956 Bristol 405 Drophead Coupe, of which only 42 were made.

Despite taking on some of the toughest roads in the world without causing any damage to their beloved car, it was once they got home and parked the Bristol in a Sainsbury’s car park that they ran into trouble.

After popping into the supermarket, they returned to find another motorist had dented their prized car.

Mr Herdman, a retired chartered accountant, said while they were travelling they were constantly warned about the dangers – from theft of the vehicle to kidnap and worse – but other than a few minor repairs, including a couple of punctures, they did not have any problems.

“It was very nice reflection on human nature. The bad thing is when we got back I leave the car in Sainsbury’s car park and find there is a large dent in the front wing,” he said.

“A car is for using, it’s not a work of art … well, it is a work of art, but it is to be used rather than put in a glass cage and admire. And so these are things you have to face up to.”

During the couple’s first 24,000 miles of their world trip, they only had to spend US$125 on repairs, while the dent caused in the car park could cost them around £300.

“I was just walking back towards the car and I thought ‘gosh, that doesn’t look right’ and there was a large dent in the near-side front wing, someone had obviously overly crocked it parking next to me and put a dent in,” Mr Herdman, 68, said.

Mr Herdman finished off the restoration of the Bristol – started by its previous owner – after buying it in 1999.

In April 2001, Mr Herdman, a member of the Royal Automobile Club and president of the Bristol Owners Club, got the classic car back on the road.

The car, which is the 29th to roll off the production line, is now believed to be worth around £90,000.

Mr Herdman has travelled 135,000 miles in the car since 2001 and believes it would have completed around 500,000 miles in total.

“We love driving it to bits, it’s a very, very comfortable car, both of us can fall asleep when the other one is driving,” he said.

“It’s just a lovely car to drive.”

Mr Herdman and his wife, 70, a retired lawyer, started their incredible journey in July 2010 from Miami, driving up the east coast of North America to Halifax before crossing Canada and then heading south down the west coast.

After a couple of months in South America, they headed across to Australia before the car was shipped back via Turkey for the drive back home to England through Europe.

The couple, who are from London and currently living in Sussex, eventually returned to England in November.

The Wazuma V8 has become the world’s most expensive quad bike with a price tag of €200,000.

Built by French company Lazareth, the one-off Wazuma V8 can hit a top speed of 241km/h and is so powerful, it is only permitted to be driven off-road.

The special bike boasts a Ferrari engine with 250bhp and handlebars from a BMW M3.

Manufactured this year, Lazareth describes the quad as an ‘atypical three-wheel vehicle’, with the rear two wheels linked together.

Weighing in at a relatively light 650kg, it also features huge 18-inch wheels with racing slick tyres.

“The Wazuma offers matchless driving sensations with a unique design,” a spokesman for Lazareth said.

“It is designed to be simple, aggressive and high-performance. It is first of all a masterpiece of engineering, a sculpture.”

It is up for sale for €200,000 on luxury website JamesList.

It’s a car enthusiast’s worst nightmare – a fleet of high-performance cars, including eight Ferraris, has been involved in the ‘world’s most expensive car crash’ after a multi-car pile-up in Japan.

A rare Zenvo Automotive ST1 supercar has gone on sale for £1.14 million.

There are only 15 of the £1.14 million Zenvo ST1 supercars – which boast a top speed of 233mph and 1250bph – in the world.

An exact replica of the Chitty Chitty Bang Bang car, which took a fan 12 years to build, is expected to fetch over a quarter of a million pounds at auction.

The world’s most expensive luxury sports car, the Bugatti Veyron, certainly attracts more than its fair share of attention.

So it was hard to miss when it was illegally parked in a disabled parking spot in Essex, England recently.

It even caught the eye of an unimpressed traffic warden, who slapped the £839,285 vehicle with a parking ticket before it had been in the space half an hour.

A crowd of passers-by gathered to admire the 16-cylinder supercar.

People stopped to take photos on their mobile phones of the car’s gleaming bodywork and sleek lines.

But a nearby traffic warden alerted to the vehicle by the crowd was not prepared to let the rich driver get away with breaking the rules.

As bystanders posed with the Bugatti, the warden filled in a parking ticket and placed it on the windscreen – which was not displaying a disabled badge.

The owner – allegedly an expensively-dressed man in his early 40s – looked (not surprisingly) unconcerned at the ticket, according to witnesses.

He simply got in his beloved car, sat back on the luxurious leather driver seat and drove away.

The Bugatti Veyron is the fastest car on earth and can accelerate from zero to 60mph in just 2.5 seconds.

Porsche unveiled its new Porsche Panamera GTS at this year’s LA Motor Show.

The new GTS is being pitched as the most dynamically focussed model in the range to date.

It is based on the 4S and is powered by the same 4.8-litre V8 engine, but it’s been tuned to produce an extra 30bhp and 20Nm of torque, pushing its output to 424bhp and 520Nm.

Porsche claims these figures will translate into a 4.5-second 0-62mph time – half a second quicker than the 4S.

Other features which set the new Porsche Panamera GTS apart are its adaptive air-suspension, which sits firmer and 10mm lower than the Panamera Turbo, its wider rear track and its bigger brakes when compared to the Panamera Turbo.

But perhaps the most exciting of features is its ‘Sound Symposer’, which is claimed to transmit engine sound into the cabin via the A-pillars.

Active suspension and Porsche’s Sport Chrono pack are fitted to the Porsche Panamera GTS as standard, and so is Porsche’s Sport Plus programme. This mode lowers the car, switches it to a firmer damping rate and adjusts the angle of the rear spoiler, producing genuine downforce at higher speeds.

Finishing touches include larger air intakes in the front bumper and an optional gloss black detailing package for the exterior, including matt black tailpipes. An exclusive body colour of Carmine Red is also available.

UK sales will begin next February, with prices set to start from £90,409.
