Gemballa Mirage GT
Based on the Porsche Carrera GT, this car, according to Gemballa, could comfortably top 1000 bhp and chase down the Bugatti Veyron. But this twin-turbocharged version of the 5.7-liter V10 has a 'mere' 750 bhp. Enough to see 60 mph in 3.4 seconds and a theoretical top speed of 250-plus mph. If it looks like a ridiculous flight of fancy, then you're wrong, as one has already found its way to Dubai. In white, of course. Look for an upcoming road test.
The Eibach AMV8 is good, but don't expect it to break the 400-mph mark. The name denotes the horses-actually, there are 425. A complete re-jig of the baby Aston uses Prodrive performance parts that add 45 hp to the bottom line and an Eibach suspension that should stick to the road like the burnt remains of its Pirelli P Zeros. Carbon fiber aerodynamic additions look the part and should help this beauty to its top end of 185 mph.
H&R Mission 400 Plus
Tucked away in a corner was potentially the heaviest hitter. The H&R Mission 400 Plus, developed with Jurgen Alzen Motorsport, will either break the 400-kph (248.56 mph) mark and threaten the Bugatti Veyron's position as the fastest production car in the world, or it will just take off and fly. It works in the wind tunnel, but when you strip a Carrera S of its wing, lower the roof by 5cm and then jack horsepower up to 1070 bhp and torque to 920 lb-ft, anything can happen. The engine comes from the Turbo model, albeit heavily reinforced. Expect the car to go for the record in the first half of 2007 with Alzen himself at the wheel. He has raced everywhere and is a Nordschleife specialist, but this should still be the hairiest ride of his life. Don't, however, expect the car to go on sale; it would kill most mortals.
Tech Art Wide Body
TechArt has gone quite mad with the introduction of the TechArt Widebody, based on the Porsche Cayman S. It's not subtle, but that's the point. And the 8cm extra width allows for a wider track, 20-inch wheels and additional cooling. The 3.4-liter engine has been bored out to 3.8, producing 385 bhp and 300 lb-ft of torque; zero to 60 mph in 4.9 seconds, 190-mph top speed.
Cargraphic GT3 RSC
Ever prepared to push the envelope, Michael and Thomas Schnarr bored the GT3 RSC's engine out to four liters, liberating 420 bhp. Cargraphic won the GT class of the 2006 Tuner Grand Prix with its 996 model, beating the more powerful GT2 models with sheer poise and balance. With the extra pace placed in the new car, we're putting a bet on for 2007.
Carlsson brought out its Mercedes CL conversion with 430 bhp under the hood. Adding a supercharger has turned the five-liter CL into a comfortable rocketship. Subtle external modifications combined with serious performance gains appeal to those with deep pockets and the determination to blitz down the autobahn. Carlsson's biggest cars are all capable of bursting the magic 200-mph bubble, normally the preserve of less refined supercars.
AC Schnitzer Tension
Production versions of the AC Schnitzer Tension, spawned from the concept launched last year, will number only 50. The base car can be anything from a 630i right through to the M6. For those cursed with small engines, Schnitzer will undoubtedly offer its 5.1-liter V8 with 411 bhp.
Abt Sportsline TT-R Dual Fuel
Abt Sportsline came to the Essen Motor Show with a dual-fuel TT-R that produces 355 bhp running on gas or LPG. It also shows that the tuning world is exploring ways to attain high speeds with less negative environmental impact. The supercharger produces almost 100 more hp, good for 60 mph in five seconds dead-almost a second faster than the standard model. A carbon fiber hood, aggressive aero kit and Abt's oversized wheels complete the visuals. It could be a supercar slayer. A clean one at that.
Based on the track-focused GT3 and inspired by the legendary 1973 911 Carrera RS, the RGT comes with a racer's look, sporting bolt-on wheelarches, an integral roll cage, and pin-sharp handling. Weight-saving measures include removing the rear seats and fitting aluminum doors that strip another 30 pounds. Then RUF went to work on the 3.8-liter engine, producing 445 bhp with the aid of titanium and high compression. The car hits 60 mph in 4.2 seconds, 125 mph in 13.5 seconds and a top speed of 197 mph. It's an expensive option at more than $230,000, but it is a RUF.
Hartge Z30 Biturbo
The BMW Z4 M Coupe is an instant classic, but it could be faster. That's where Hartge steps in with its twin-turbo Z30 Biturbo. Now this monster pumps out 380 bhp and 330 lb-ft of torque. It also sports a new suspension, an advanced limited-slip differential (that should help even average drivers slide everywhere on armfuls of opposite lock), and a body kit that adds more muscle. It weighs less than the M Coupe, at 3069 pounds, hits 60 mph in 4.8 seconds and will rocket close to 180 mph.
As well as the CLS-based Rocket that breached 228 mph at Nardo, Brabus brought its T13 tuning kit fitted to an S600. This system includes new turbochargers, a more efficient intercooling system and low back-pressure catalytic converters, as well as reprogrammed engine electronics. Output climbs from 517 to 630 bhp, with torque jumping from 612 to 738 lb-ft. This car hit 203 mph at Nardo and 60 mph in less than 4.3 seconds-right behind the Rocket, and fast enough for an executive barge.
Mansory Continental GT
The workers at Crewe might not be too pleased to see what Mansory has done to their Continental GT. This Widebody version comes in black and orange, and the garish color scheme is continued inside with luminous orange Alcantara trim. Extended wheelarches, a plunging front end, rear wing, and twin-spoke wheels provide all the menace required and more. Under the hood, Mansory has pulled 650 bhp from the six-liter W12 and knocked half a second off the standard model's zero-to-60-mph time. It now clocks 4.5 seconds and tops out at 202 mph, not bad for a car that weighs more than 5060 pounds.
