There are six modded Genesis’ planned for SEMA: three coupes, three sedans. The coupes have been worked over by Street Concepts, HKS, and Rhys Millen. A rendering of the first tricked-out Genesis sedan from RKSport has rumbled onto the page, and it looks less like competition for the 5 Series than it does a challenger to the Death Star. The Platinum Silver sedan will wear carbon fiber accessories and a couple of spoilers as it hunkers on its oversized TSW wheels.

RKSport’s take on this car is to raise the performance stakes, and it’s going to have Hyundai’s help doing it. The whipped cream on the sunday will be a K&N air intake, Magnaflow exhaust, Eibach springs, Baer brakes, and a body kit. The sunday itself consists of performance upgrades that Hyundai is giving to the car’s Tau V8 engine. The Korean automaker is hush-hush on those changes, but they’re probably good for a bump in the numbers in all the right places. And since you can’t drive the cars at SEMA, they’ll probably look and sound pretty good, too.

Scion’s been a perennial SEMA attendee for the last five years, with customization being a central tenet of the brand. This year, the cool-seeking Toyota nameplate is bringing a sextet of vehicles, three each of tCs and xBs, all customized. The xBs were sent out to customizers to get thematic treatments. The three art cars embody different ideas; one’s a camper in the vein of Westfalia Volkswagens, another’s been chopped and dropped to create a lakebed hot rod, while our favorite is an ersatz Roach Coach. Blaine Fontana was responsible for the camper conversion, while Jeff Soto whipped up the salt flats car, and Kenton Parker decided to celebrate the xB’s non-curvy shape with the foodservice conversion.

Bonneville speed trial cars serve as inspiration for one of the customized tCs, as well. Scion distributed three tCs to customizers for the 2008 Scion Tuner Challenge, with the winner to be announced during SEMA. Eddie Hahm of “Fast Eddies Garage” fame took it retro and created an homage to a time when hot rodding meant more than mounting dubs and a bodykit. Fatlace founder Mark Arcenal dreamt up a DTM racer, while John Pangilinan made an even more butch looking tC with his widebody design. These six cars are sure to be just some of the Scions at SEMA. Indeed, there will be several other custom Scion models at the brand’s booth, like an xD with its top chopped. We’d be down with some of these customs, even if underneath it all, they’re still Scions.

Steve Saleen’s fledgling new company, SMS Supercars, is getting ready to officially debut its first production car and has released a few more photos and information regarding the 570 and 570X Challenger. According to the new press release, the two models are targeted to start at $60,000 and $70,000, respectively. Yes, that’s quite a chunk of change, but SMS is making it worthwhile with an extensive list of upgrades. Starting with the powertrain, the SMS 296 supercharger pushes massive amounts of air to the 5.7L HEMI, and true enthusiasts will be glad to know that a proper 6-speed manual transmission will be doing the shifting. Both models also get a high performance suspension, exhaust, 20-inch wheels, and 14-inch front and 12-inch rear brakes. For the exterior, SMS replaces the front and rear bumpers, side skirts, and hood, and adds a rear spoiler. The 570X model also receives carbon fiber front and rear splitters, a carbon fiber diffuser, and a rear wing that replaces the spoiler. The interior receives upgrades as well, including two-tone leather sport seats, leather door inserts, a leather grip shifter, 200-mph gauge cluster, and auxiliary gauges for the supercharger. Each vehicle will also be personally signed by Steve Saleen.

Not many cars can compete with the Lamborghini Murcielago Spyder’s ability to attract attention. With 640 horsepower on tap, not many cars can keep up with it either. Even German tuner IMSA questioned whether the car could be improved, but, of course, that didn’t stop them from trying. They have developed an engine package that pumps the V12 up to 708 horsepower, knocking off a tenth in the sprint to 60 mph and raising top speed to 217 mph. IMSA adds its GTR widebody kit as well that includes a new front bumper, side skirts with widened intakes, a carbon fiber diffuser and rear spoiler. Inside, the carbon fiber and leather seats have been color-matched to the exterior. It’s not necessarily everyone’s taste, but it is wickedly fast and sure to attract attention.

If you’re one of those take-no-prisoners off-road types, then we’ve found the perfect camper trailer for you. It’s called the Tvan, and it’s made by Track Trailer. The company, Australian-based and located outside Melbourne, has been in business since 1982. Their Tvan model is specially engineered to eliminate the problems found with conventional flip-over type campers (which stow the tent on the bed). With the Tvan, the tent is stowed in the rear hatch allowing your bed to be kept clean and dry. Even better, a hard roof over your head ensures a better night sleep.

As Track is experienced building military trailers, much of their heavy-duty technology finds its way into the Tvan. Features such as an asymmetric link suspension with Koni shock absorbers, 10 inches of wheel travel, and a 30-degree departure angle allow the trailer to follow the tow vehicle over nearly every terrain. With a hot dip galvanized steel frame, it is also built to take abuse and last. Of course, the kitchen appointments are stainless steel with abundant power outlets, lights, and ventilation to take the edge off of roughing it. It even comes with a 70-liter “food grade” water tank as standard equipment. Now, we found you the camper, you just have to figure out how to get it here… unfortunately, the Australian company isn’t shipping to the States.

When you think about the Toyota Venza, we doubt the first thing that comes to mind is customization. But that hasn’t stopped Toyota from tapping Street Image, Inc. and long-time partner Five Axis to create a duo of Venza project cars for November’s SEMA Show in Las Vegas.

The two low-slung crossovers (don’t call them wagons) attempt to highlight and accentuate the active lifestyles of the Venza’s core demographic, beginning with the Street Image variant (above) that boasts an upgraded engine and brakes, massive rollers, a lowered ride height, body kit, a black/burgundy interior and a sat-nav-equipped entertainment system. Toyota says the Street Image SportLux version attempts “to give the occupants the feel of a refined sports car while retaining the Venza’s utility and functionality.” We say, good luck.

Five Axis makes a slightly more compelling case for customizing the Venza with a stow-away rack system created by Magna Car Top Systems that can transport everything from bicycles to skis. New front and rear bumpers, wider fenders and pot-hole averse 20×10.5-inch wheels round out the exterior mods on the Venza AS V.

We’ll be checking out both models in Vegas in a few weeks.

Every autumn the naval base on Coronado island in San Diego plays host to dozens of vintage car racers for a festival of speed as part of Fleet Week, the largest military appreciation event in the country. The runways are a natural asphalt playground, and the Southern California weather never fails to provide plenty of sunshine. Nine separate classes of cars run throughout the weekend, from Pre-1941 Sports and Racing cars all the way to 1966-1972 Historic Trans-Am cars. Our particular favorite were the 1955-1960 Sports Racing cars that included a stunning 1957 Ferrari 250 TR, a pair of Jaguar D-Types, Maserati T-61 Birdcage, and a beautiful Aston Martin DBR-2. Spectators could also take tours of the pit area, browse the Meguiar’s car club corral, take Naval ship tours, and explore a display of modern military vehicles and planes. We didn’t stray much from the track, however, so that we could bring you plenty of photos of all the different groups of cars.

With the M5-battling Jaguar XFR looming high on the horizon, German tuning house Arden’s release of its new AJ21 comes at the perfect time. The XF-based performance sedan, details of which have been trickling out for several months now, offers a range of modifications to give the sharp cat that extra edge.

As you can see from these new images, Arden’s given the Jag’s appearance a serious makeover, much to the benefit of its aerodynamics. The front end has been thoroughly redesigned to include a bigger grille and vents to help the engine get the air it needs, while the front spoiler keeps things planted. Around back the diffuser and discreet spoiler keeps the tail nailed as well, with side skirts helping along the way and integrated vents to help cool the rear brakes. The package also includes a revised suspension and 21-inch forged alloys, but the real treat is underhood where Arden has worked its magic on the entire range of engines available on the XF. The range-topping supercharged V8 has been bored out from 4.2 liters to 4.5 and is aided in producing 500 horsepower by a custom crankshaft, con rods and pistons. The same enlargement can be done to the naturally-aspirated V8 for 380 hp, with the 2.7-liter diesel six tuned to 250 hp instead of the stock 207.

We loved the look and concept of Katech’s Corvette Z06 ClubSport that we showed you last month, as did many of our readers. The emphasis on light weight components and track-ready components make it suitable for both street and racing duties, plus it’s one of the most beautiful renditions of the Corvette we’ve seen to date. Our only complaint was that Katech provided just one photo to drool over. Fortunately, they remedied the situation by sending us a set of beautiful high-resolution photos, which we’ve added to the gallery below. You can also view more info on the car in the press release after the jump in case you missed it the first time around.

The Firehawk name is well known by GM performance buffs, having graced some of the highest performing Firebird models from 1991 until 2002. Built by New Jersey based SLP (Street Legal Performance), the Firehawk models received various levels of performance upgrades and could hang with the best of American muscle during its day: the later models could run 0 to 60 mph in around five seconds and passing the 1/4 mile in the mid 13’s. While the Firebird wasn’t revived along with the Camaro, SLP has decided to use the G8 to revive the Firehawk name with three special edition cars based on the V6 and V8 models as well as a supercharged version. The cars will be sold through Pontiac dealers and will carry a full warranty. Sound great, right? Current Firebird Firehawk owners don’t think so. After hearing the news on LS1Tech.com, many of the members were outraged that the Firehawk name would be watered down on something besides a Firebird, in particular a four door sedan. In all fairness, SLP owns the Firehawk name and can use it how it wants, so we’ll reserve judgment until the car is actually unveiled and we can see how it performs. Thanks for the tip, Russ!
