Among the many turbocharged tuner cars and monster-truck four-wheelers crowding the SEMA showfloor next week, there will be a cadre of Lincoln MKS sedans, suitably modified but standing somewhat back from the extremism of the rest of the show. Three of the cars will be on display, each offering a...

Combining the 2.5L turbocharged powerplant from the WRX STI with the Forester's roomy platform, the Forester XTI show car is one of the highest-performance SUVs this side of a Cayenne. Due for debut at the 2008 SEMA next week, the Forester XTI also lays claim to a 0-60mph (96km/h) time of less than...

While Chrysler may have ruled out adding a convertible variant of the 2009 Dodge Challenger, no fewer than three open top versions of the rejuvenated muscle car will be on show at this year’s SEMA event in Las Vegas. The first custom convertible, announced two weeks ago, is the creation of...

As the annual Specialty Equipment Market Association (SEMA) show in Las Vegas draws near, more details of the cars that will be on show there trickle out.

Techart is well known in the aftermarket tuner scene for creating some of the greatest performance kits for Porsche cars, so it comes as little surprise that there has been plenty of interest in the German tuner’s latest kit designed for the facelifted 911 range. The GT Street R is fitted...

It's hard to imagine truly making the Audi RS6 any better at what it is: one of the most insanely powerful and over-the-top family cars around. But the gang at DKR Tuning have applied their skills at ECU tuning to deliver another 80hp (59kW) and some mildly upgraded aesthetics to the already strong...

Techart is well known in the aftermarket tuner scene for creating some of the best functional aerokits for Porsche cars, so it comes as little surprise that there has been plenty of interest in the German tuner’s latest kit designed for the facelifted 911 range. The pieces are constructed...

Modified Mercedes-Benzes are far from uncommon,and the methods applied are likewise becoming rote: big, flashy wheels, a new, agressive body kit and, of course, more power. Lorinser sticks with this tried and true formula and ends up with something not to far from the manufacturer's specifications...

One of the most highly modified Pontiacs at next month’s SEMA Auto Show won’t be an official General Motors offering but the car should serve as a major endorsement for the ailing carmaker and could even boost interest in the tuning scene for one of its top models. The car is a fully...

ABT Sportsline is a specialist when it comes to modifying Audi vehicles but the German tuner’s usual assortment of modifications involves some serious horsepower numbers and extensive body work. Its latest creation, on the other hand, could best be described as automotive artwork and is...

Nearing the celebrated 100hp/liter metric...

The Lexus IS F is something of an enigma - at once an entry-level luxury sedan and a performance beast, offering legitimate power figures but hampered somewhat by its automatic transmission. Another of the problems those that ply their IS Fs on the track may have bumped into is the speed limiter -...

The Ford Mustang is many things to many people, but rarely is it considered an efficient or 'green' vehicle. A German LPG advocacy group and tuning shop Rollin on Chrome have come together to change that perception, however, producing a 300hp (228kW) LPG-fueled custom Mustang GT, which joins the...

German tuner Irmscher is a specialist when it comes to modifying Opels, having worked with the brand for more than 40 years and previously installing a V8 engine in the compact Opel GT. Not surprisingly, it's one of the first companies to work on the new 2009 Insignia sedan, and has now released a...

Unlike some of the recently announced and soon-to-be-shown SEMA design concepts for the Mercedes-Benz GLK - one of which was even done by Brabus - the Brabus version of the GLK that will see public sale is considerably more restrained. With no gratuitous side-scoops, a minimal front-end redesign...

The 2009 Chevrolet Corvette ZR1 is currently listed at a lofty $103,300 (not including taxes) but you can get similar performance in a standard Corvette, at least in a straight line, with the addition of Katech’s new 'Air Attack LS7 Supercharged' crate engine. The latest powerplant from the...
