As if it needed any help, the good folks at ABT have taken the R8 and made it even faster. The result is the ABT Audi R8 V10 ($TBA). By tuning the 5.2L FSI engine, they've increased the horsepower from 525 to 600, good for a 0-62 time of 3.5 seconds and a top speed just short of 200 mph. The upgrades don't end there, though: the upgraded R8 also features a new aero kit, new 19-inch wheels, a new exhaust system, and new suspension springs that lower the car slightly, providing even better handling.

2014 Porsche 911 Turbo

This isn't your normal mid-model refresh. The 2014 Porsche 911 Turbo ($148,000 and up) is an all-new model, and as such, it's packing some new goodies. Features like a new all-wheel-drive system, active rear axle steering, adaptive aerodynamics, an entirely new, longer chassis, 20-inch wheels, Porsche Dynamic Chassis Control active anti-roll system, and full-LED headlights. It hasn't lost its edge, either, boasting a turbocharged 3.8-liter six-cylinder engine that pumps out 520hp in the standard model and 560hp in the S model, paired with a seven-speed dual clutch transmission that gets you from 0-60 in as little as 2.9 seconds and to a top speed of nearly 200 mph. They'll be rolling off the boats from Germany just in time for the holidays — so here's to hoping you have a very, very generous gift-giver on your list.

Syrena Sport

It's not that unusual for a classic car to get a modern update, but normally the car's prior version actually made it into production. The Syrena Sport ($TBA), on the other hand, is based off a 1950s prototype that never got the chance to grace a showroom floor. This modern take is based on the Nissan 370Z, and is powered by a 3.7L V6 — instead of the twin-cylinder boxer of the original — that's good for 330 hp naturally aspirated or 450 hp in a turbocharged version. Other features include updated styling and a curb weight under 2,900 lbs. The bad news? Only one example is currently scheduled to be built.

2014 Jaguar XKR-S GT

Sometimes raw power isn't the only upgrade that matters. Although the supercharged 5.0-liter V8 that powers the 2014 Jaguar XKR-S GT ($174,000) is the same as the standard XKR-S with an output of 550 hp, the GT is far better equipped to take on the track. Why? Well, it's the combination of a new aerodynamics package that includes a carbon fiber front splitter, dive planes, extended wheel arch spats, rear diffuser, an aluminum undertray, and a huge carbon rear wing, larger carbon ceramic brakes, wider 20-inch forged alloy wheels, a stiffer suspension, and a revised active exhaust system. The result? A street-legal racer that goes from zero to 60 in under four seconds, boasts a top speed of 186 mph, and will be limited to just 25 cars in the US when it goes on sale in August.

Spyker B6 Venator Concept

Drawing on a heritage that dates back to 1880, the Spyker B6 Venator Concept ($150,000) hopes to rekindle love for the brand with a meticulously built speedster. This two-door, mid-engine affair will be powered by 350hp V6 that mates with a six-speed automatic to drive the 19-inch rear wheels. The aluminum frame and carbon fiber help keep the weight down, while the oversized radiator grille, the 1903-era logo, a turned aluminium fascia on the dashboard, and red cover on the ignition switch recall Spyker's automotive and aeronautical past. Unlike most concepts, the B6 is slated for production; expect to see it stateside in Autumn 2014.

1955 Maserati A6G/2000 Spyder

Perhaps one of the most beautiful automobiles ever created by the Italian luxury carmaker, the 1955 Maserati A6G/2000 Spyder ($4.5 million) is a picture of automotive elegance. One of the only convertibles ever produced in this model, the car features a two-liter straight six producing 180 brake horsepower. This particular car has been lovingly restored to its original condition, with beautiful paint and bodywork, as well as an immaculately-appointed interior. The car was originally built in very limited numbers, and manufactured by a variety of Italian coachbuilders — while this one in particular was constructed by the legendary Carrozzeria Zagato.

Mercedes-Benz SLS AMG GT3 45th Anniversary Edition

Most high-end sports cars try to get as close as possible to full-on racecar capabilities while maintaining street-friendly looks and interiors. Created to celebrate the anniversary of the first SL model, the Mercedes-Benz SLS AMG GT3 45th Anniversary Edition (€446,250; roughly $580,000) says to hell with all of that. It's a true racer, with a ton of parts made from lightweight CFRP, an AMG 6.3-litre V8 engine hand-fitted with help from Bernd Schneider, a special magno graphite matte paint job, a steel roll-over cage, and six-point seat belts. The best part? You and the other four people lucky enough to own one get to pick their new rides up at Mercedes-AMG in Affalterbach, and can even get some race track coaching while they're there.

Maserati GranCabrio MC

Four seats, two doors, no roof — that's the formula for making a Maserati GranCabrio MC ($TBA). Okay, so maybe there's a bit more that goes into this high-powered convertible. Inspired by the GranTurismo MC Stradale, it features a sporty, aggressive body that's longer than the standard GranCabrio, a front end taken almost directly from the MC Stradale, and a rear that's dominated by the large spoiler, which gives greater negative lift at high speeds and houses the third brake light.

The 2013 Hennessey VR1200 Twin Turbo ($TBA) is based on Caddy's sporty coupe, but bests it in the performance department thanks to a twin-turbo 7.0L V8 pumping out 1,066 rear wheel hp — allowing it to rocket from 0-60 mph in just 2.9 seconds on its way to a top speed of 242 mph. Upgrades are also made to the camshaft, fuel system and injectors, brakes, wheels and tires, suspension, sway bars, and interior. Of course, no high-end sports car would be complete without some carbon fiber, which you'll now find on the front splitter, rear diffuser, front fenders, hood, and rear flares.
