Drag Race: VW Golf R vs Touareg V8 TDI

Well this is awkward. We're usually used to seeing supercars go at each other, not diesel SUVs and hatchbacks. Still, none of these two cars could be called "slow" in any way.

As you know, the Golf R isn't just a family hatchback. Well, it is, but it's no entry-level petrol-burner. It's got a 2.0 liter turbocharged engine, sending 300 HP to all four of its wheels, which is a recipe of fun regardless of where you live.

The Golf R can reach 62 mph (100km/h) in 4.9 seconds, which no too long ago was supercar territory. The first gen 4.2 FSI Audi R8 hit 62 mph in 4.8 seconds if you remember. So we have ourselves quite a capable hot hatch over here.

In the other "corner" we've got size and we've got torque. Precisely 340 HP and no fewer than 800 Nm (590 lb-ft) of torque. There is of course a massive weight disadvantage but also a disparity in mid-range pulling power.

If the two cars met from a rolling start, we'd actually expect the heavier yet torque-happy Touareg to jump out in front, at least for a bit. But seen as though this was a standing start, it just couldn't get off the line as quick as the much lighter Golf R.

Even so, it was an interesting match-up, and they measured the time/speed all the way up to 160km/h (99 mph). So in the end, we have a pretty clear picture of what the difference is between these two cars.

2012 Aston Martin Vantage V8

Aston Martin is really trying to tell us is that it has upgraded the base Vantage V8 with many of the improvements first seen on the Vantage S.

While the standard six-speed manual transmission remains, the optional six-speed Sportshift automated manual transmission has replaced with the seven-speed Sportshift II.

In addition, the base V8 model gains the Vantage S' quicker steering with a ratio of 15:1 compared to 17:1, bigger brakes with 380mm two-piece ventilated cast-iron front discs and six piston calipers, and 10mm wider tires.

On the outside, the 2012 Vantage V8 inherits a number of styling changes from the Vantage S and N400 limited edition, which include a new lower front bumper piece with a splitter, more sculpted side sills and and a rear diffuser.

The base Vantage's 4.7-liter V8 engine that produces an output of 420bhp (426PS/313kW) remains intact.

The technical and styling changes have been applied to both the V8 Vantage Coupe and Roadster models, with prices starting from £84,995 in the UK and from €108,500 in Germany.

Production of the other Vantage models, which include the Vantage S featuring a 430bhp version of the 4.7-liter V8 along with a bespoke sports exhaust system and a carbon fiber aero package, and the 510bhp Vantage V12 continue unchanged for 2012.

We'll remind you that Aston recently also launched the V12 Zagato , which assumes the role of flagship model of the series and will be produced in a strictly limited run of 150 units.

2012 Maserati GranTurismo Sport 460HP V8

The Sport model is motivated by an improved version of Maserati's 4.7-liter V8 engine that gains 10bhp over the outgoing S model for a total output of 460-horsepower.

There are some visual changes on the outside too, namely the redesigned front bumper with larger air vents, tweaked headlamps with DRL Led technology and darker tail lights.

While Maserati has not yet published any photos of the interior, the Italian company tell us that the Sport gets a brand new set of front and rear seats and a new steering wheel "with a more sporty and muscular look".

2013 Audi S8 4.0-liter Twin-Turbo V8 with 520-Horses

The German firm's engineers further honed the 4.0 TFSI pushing output to 520-horses and a constant 650 Nm (479.42 lb-ft) of torque to the crankshaft between 1,700 and 5,500 rpm.
Power is channeled to all four wheels through an 8-speed automatic transmission and Audi's permanent all-wheel drive system, with Audi making claims of a 0-100km/h (62mph) sprint time of just 4.2 seconds, or 0.6 and 0.7 seconds faster than the 420HP S6 sedan and S7 Sportback, respectively.

The V8 engine features a cylinder deactivation system that can cut down one bank to become a 4-cylinder , as well direct-injection technology, plus energy recuperation and start-stop systems.
As a result and despite a 70HP increase in output over the previous 5.2-liter V10-powered S8, Audi says average fuel consumption has decreased by nearly 23 percent at 13.2 liters per 100 km (17.8mpg US).

To improve handling, the S8 gets a specially tuned adaptive air suspension with variable damping, which can vary the ride height of the body between three levels, and four internally ventilated disc brakes that measure 400mm (15.75 in) in diameter up front and 365mm (14.37 in) at the rear, with carbon ceramic disks offered as an option.

As with other members of Audi's S family, the styling touches on the S8 are subtle. On the outside, apart from the 20-inch alloy wheels shod with 265/40-series tires, the 5.15 meter-long (16.90 ft) S8 gets a different grille treatment, a front apron with a lip spoiler, and a revised rear bumper that incorporates a diffuser and four tail pipes.

Interior modifications include the usual, meaning sport seats, a sport steering wheel and –you guessed it- sportier looking trim.

2012 Mercedes-Benz SLK 55 AMG

Power for the roadster comes from a new naturally-aspirated AMG 5.5-liter V8 engine that delivers 62 more horses and 30Nm more torque than the previous model's eight-cylinder unit, at 422-horses and 540Nm in European-spec, and 415-horses at 6,800 rpm and 398 lb-ft at 4,500 rpm in North American-flavor.

The aluminum V8 engine also features the AMG Cylinder Management system that can shut off four-cylinders from 800 to 3,600 rpm to improve fuel efficiency.

A 7-speed AMG Speedshift automatic transmission featuring three modes (sport, manual and efficiency) transfers power to the rear wheels.

According to the Mercedes, the new SLK 55 AMG completes the standard 0-100km/h (62mph) sprint in 4.6 seconds and reaches an electronically limited top speed of 250km/h (155mph).
The roadster returns a combined fuel consumption of 8.5 lt/100 km, which is 3.5lt or 30% less than that of the preceding model with the 360HP V8.
