Being scared of cars isn't unhealthy. Rather, it's a sign of respect for what four wheels, thousands of pounds of mass and gobs of power can do to yourself and others when forced to an immediate, screeching and metal-crunching stop. It's a good feeling. It makes you feel alive. Click "next" to see the cars that get our hearts racing.

Car: TVR Cerbera Speed 12

Why We're Afraid Of It: Starting with the obvious: it's a TVR. The specs almost match up with the Veyron except, you know, it's much lighter. And why is it so much lighter? No complex crumple zones, safety equipment, or electronic nannies to weight you down. But hey, you didn't buy one thinking you were going to live that long anyways.

Car: Dodge Viper SRT10

Why We're Afraid Of It: It'll burn you one way or another. It'll either leave a "Viper tatoo" of charred flesh along your calf as you exit or, if not given the proper respect, out the narrow front windshield. All power and no visibility make this a toy only for the well insured.

Car: Caterham R500

Why We're Afraid Of It: If the Caparo T1 is like driving an F1 car, the Caterham R500 is like driving a motor and not much else. It does 0-to-60 MPH in... NOW. At a hair over 1,100 pounds it's got a power-to-weight ratio of 520 HP-per-ton. Windscreen and heart pills optional.

Who Is Most Afraid Of It: Arcsine

Car: Any Cobra Replica

Why We're Afraid Of It: Oversteer is a helluva drug. Shops like Factory Five have continued to pour more power into Cobra replicas and, in the name o fidelity to Shelby, not much else. It's basically the best way imaginable to piss your pants.

Car: Porsche 930

Why We're Afraid Of It: Though it's the best sort of being scared, the original Porsche 911 Turbo was one of the earliest production vehicles to feature turbocharging. With around 400 HP coming out of an engine hanging out the back, the physics of the 930 are questionable and become that much more frightening when you throw in überturbolag. Stay on the throttle and it'll, almost magically, get you around the corner. Lift and you're toast.

Car: Wienermobile

Why We're Afraid Of It: We enjoy driving the occasional commercial truck, but when you remove the box and throw on an awkward and top-heavy dog-in-bun costume things change a bit. Based on a GMC platform, the latest big Wienermobile is powered by a 300 HP, which is completely manageable. What scares us the most about this particular vehicle is everyone else on the road swerving into us while trying to take video with their cell phone. We hear it's worse than a Bugatti.

Who Is Most Afraid Of It: PDQ2

Car: LS-Powered Cars That Aren't LS Cars

Why We're Afraid Of It: Whether LS1 or LS9 not all cars were intended for large, powerful V8 engines. And while throwing out a flat-head six in an old truck and dropping in an LSwhatever feels right, a Corvette-powered Chevy Aveo or Corvair is a proposition only for those without a history of heart problems.

Who Is Most Afraid Of It: Dmartino

Car: Dodge Caliber SRT4

Why We're Afraid Of It: Sure, 285 Horsepower isn't that much, until you consider it's been put in a vehicle barely designed to handle 100 HP. Buy hey, FWD cars with lots of power isn't necessarily bad, it's why God created differentials... except this doesn't have one. It has a "braking" diff that just hard-brakes one of the wheels on you. It's as comforting as it sounds.

Who Is Most Afraid Of It: Us one winter in Chicago.

Car: Caparo T1

Why We're Afraid Of It: It's considered the F1 car for the street. We'll reiterate: it's the F1 car for the street. Lots of power, not much weight, limited protection, and it nearly killed Jeremy Clarkson. Where do we sign up?

Who Is Most Afraid Of It: Motor_Yakuza

Car: Chrysler Sebring

Why We're Afraid Of It: The Chrysler Sebring Convertible doesn't have half the power most of the cars on this list have, but it feels like it's made of tin, drives like its tires are coated with astroturf, and is so loud with the top down that you're sure death is but a pothole away.

Caterham R500 immortalised – in LEGO
The Caterham Superlight R500 won accolades across the board in 2008, including the prestigious Top Gear Car of the Year.

But you know you've really made it when you're built in LEGO.

LEGOLAND designers were so impressed by the R500's achievement in winning the BBC's top motoring decoration last year that it decided to capture the moment in its famous coloured plastic bricks.
Taking their place within the 40 million-brick MINILAND, one of a number of attractions at LEGOLAND, Top Gear presenters Jeremy Clarkson, Richard Hammond and James May, plus the elusive Stig, can be seen huddled around the famous Caterham Seven in a motorsport-themed area.

As well as gaining the Top Gear award, the £38,000 Caterham Superlight R500 proved its giant-killing potential by outpacing supercars like the £1 million Bugatti Veyron.

LEGOLAND'S chief model maker, Guy Bagley, said: "My colleague remembered that the Stig had put the R500 through its paces and how incredible it was on the track. It's such a timeless and iconic car that it was a ‘no-brainer' as our choice for the motorsport area, having already decided to feature Top Gear. Its design lends itself particularly well to our bricks, too."

THE NEW CATERHAM R500 - HARDER, BETTER, FASTER, STRONGER

* 520bhp-per-tonne
* 0-60mph in 2.88 seconds
* 2.0 litre Ford Duratec engine tuned to produce 263bhp
* All-new electronic dashboard including keyless ignition
* Optional upgrade sequential gearbox & launch control

For those really serious about their driving, the famous supercar-slaying R500 moniker is back with the arrival of the all-new Caterham Seven Superlight R500.

The latest model from the British sportscar manufacturer takes the minimalist, lightweight Seven philosophy to a new level with more power, sharper handling and for those venturing on track the option of launch control and the Caterham Motorsport engineered sequential gearbox.

Weighing just 506kg and producing 263bhp, R500 is the most potent race-tuned production Seven yet.

The Series 3 chassis flagship model blasts out 520bhp-per-tonne and is capable of propelling itself from 0-60mph in 2.88 seconds, delivering a pure adrenalin fix for those committed enough to strap themselves into the Kevlar race seats.

The original R500 was legendary, with the old Rover K-series powered machine rewriting performance records for 0-60mph and 0-100-0mph times. This new variant has been equipped to supersede its predecessor by embracing the very latest in lightweight engineering techniques and technology.

Lurking under the lightened bonnet is the all-alloy 2.0 litre Ford Duratec engine. Fed by its roller barrel throttle bodies, the normally aspirated, four-cylinder mill is tuned by Caterham Powertrain (CPT) to unleash a monster; 263bhp with a heaving 177 lb-ft of torque transmitted to the rear wheels. The relentless acceleration is transmitted through each ratio by either the standard 6-speed gearbox or the optional Caterham Motorsport engineered sequential transmission.

To help reign in such extreme performance are race-developed Avon CR500 tyres and a suspension set-up that includes weight saving aero wishbones and fully adjustable dampers. Bringing things ferociously to a halt are four-piston calipers clamping on vented discs at the front and lightweight twin piston rear calipers.

Performance upgrades for the R500 aimed squarely at the track day market include a sequential transmission, launch control, a gulping Carbon Induction Airbox and Eibach Springs and dampers derived from the Caterham C400 race series.

The R500 isn't just about big performance statistics though; refinements and Seven firsts feature throughout and help distinguish it from its stablemates.

In true Colin Chapman spirit, engineers sought to add lightness to the chassis in order to improve the overall performance.

To shed a massive 9kg from the already featherlight chassis utilised by the R400, Caterham left no bolt unscrewed - more carbon and Kevlar feature than previously, thinner body panels have been utilised right through to aluminium rear light housings.

Discreet exterior styling tweaks carried over from the flagship CSR models offer both form and function - the carbon winglets increasing downforce and the cat's tongue grill aiding cooling and aerodynamics. A carbon leather boot cover and clear rear lights are also new.

Housed within the revised chassis is keyless ignition, a quick-release Momo steering wheel with integrated indicator switches and an innovative dashboard featuring flush fitted switchgear, ACES sequential gear change lights and a new Stack display with scrolling text. The carbon dash is also finished with a detailed engraved plaque to show each car's number.

On sale immediately, the factory built Superlight R500 starts at £36,995,

According to PistonHeads, the R500 Superlight is supposed to weigh less than 1080lbs. The power-to-weight ratio is said to be about 500 HP/ton, but who knows for sure what kind of "tons" those are, still word is we should expect 0-60 time of under 3.6 seconds. So will this be another uncontrollable beast, or a divine driving dream? We'll just have to stay tuned and find out. [via PistonHeads]
