Hyundai's trifecta of SEMA-bound Genesis Coupes is complete, and the latest tuned, rear-wheel-drive two-door comes courtesy of Street Concepts. Unlike the turbo'd models from RMR and HKS, the Street Concepts Coupe is packing the 3.8-liter V6 fitted with a custom cold-air intake and a Magnaflow exhaust. According to Street Concepts' owner, Shawn Williams, their aim is to "maximize the driving capabilities of the Genesis Coupe while striving for a level of practicality..."

To that end, the only performance mods – outside of aiding the V6's breathing – include a modified suspension, Brembo brakes and 19-inch Volk wheels shod in performance rubber. The exterior benefits from a black camo and "stealth fighter-inspired paint design," along with tinted head and taillights, APR rear wing and custom grille. Inside, carbon fiber trim joins a pair of Cobra seats with black suede accents and an Infinity audio system.

With the Coupes covered, we're waiting to see who Hyundai tapped to tune its three Genesis sedans. We're sure they won't be nearly as entertaining on the track, but a few VIP-styled sedans could do a lot to stoke the image of the Genesis.

Somebody's got to beat back the ugly afflicting the four-door Porsche Panamera when it arrives. 9ff, the Dortmund, Germany-based firm, is actively recruiting orders for its tuned version of the highly anticipated curve-ball from Porsche. There are no details or pictures on the 9ff website, though there is a rendering showing a slightly abstract version of how a warmed up Zuffenhausen sedan may look. While we're sure the car will be an awesome performer, 9ff will push the envelope even further. It's a brilliant bit of marketing -- basically selling shares in the tuner's Panamera program before the car has arrived. If enough orders come in, the company will be flush with cash to develop the fastest, most hideously nasty looking car to ever wear the Porsche crest. Yes, even worse than the Cayenne and its nostril fetish.

A third teaser shot of Lamborghini's mysterious concept car has surfaced on the web just weeks before its debut at the 2008 Paris Motor Show. All signs point to a front-engine, four-door coupe concept similar in form to the Porsche Panamera and Aston Martin Rapide. The first teaser merely showed the car's rear diffuser, but the second showed its front wheel with a fender vent clearly visible that indicates a front-mounted engine. This third teaser shows the rear taillight and what we can clearly see as the cut line for a trunk lid. The taillight itself features LEDs and seems to be inspired by new taillight designs on the Reventon and LP560-4. Though we don't have a name for the concept yet, Lamborghini recently registered the name "Urus" with the Italian copyright office. All will be revealed soon enough, though expect a few more teasers between now and Paris.

Live images of the Chevy Orlando, possibly shot during GM's own photo session, have surfaced online, showing the seven-seat crossover in all its conceptual glory ahead of its unveiling at the Paris Motor Show next week.

The Orlando shares the same Delta II platform as the Chevy Cruze, with power provide by a 2.0-liter turbodiesel, and blends some traditional Chevy styling cues with a blocky, upright silhouette and show-friendly lighting tricks. Unlike other pie-in-the-sky concepts, the Orlando's interior looks downright drivable, with two-tone leather seats, a traditional steering wheel and a center stack that wouldn't shouldn't look out of place on anything rolling off the General's assembly line.

Clean diesel or hybrid drive? It's an intriguing question, and one that's not quite so easy to answer. There's the price of diesel fuel to consider, which runs a few dimes over that of regular gasoline. Then there is fuel mileage. Does the Volkswagen Jetta TDI have a shot at dethroning the Toyota Prius as the undisputed mileage champion of the U.S.? To get a preliminary answer to some of these questions, Popular Mechanics put almost 500 miles on both cars, dividing up their miles between the city and the highway. It's not a knock-out for either car, but it may offer some early answers to a few questions.

First, the mileage. In the city, there's just no beating a hybrid, which uses its electric motor to good effect and scores over ten mpg better in the stop-and-go traffic of Los Angeles. On the highway, though, the Jetta TDI is able to eke out a narrow victory, scoring less than one mile per gallon better. Once the price of crude is factored in, the Prius remains the overall cheaper car to keep filled up. Of course, there is more to the story than that, including which car is a better to drive -- according to PM, the Jetta. Finally, the TDI qualifies for a $1,300 tax credit that the Prius can't claim. It's too close to call. Expect a rematch soon enough.

Ford and GM claimed losses of over $20 billion in the second quarter of 2008, which is more than the GDP of some developing countries. Chrysler has seen larger sales decreases than its fellow Detroit automakers, but in terms of cash losses, team Pentastar is way ahead of the domestic pack. Chrysler CEO Bob Nardelli gave dealers the financial lowdown Tuesday, but declined to provide details to reporters. Even though Chrysler's losses of $400 million are far less daunting than its U.S. counterparts, the Auburn Hills, MI automaker is far from overjoyed. Nardelli told dealers that the losses came in spite of large-scale cost cutting, and he mentioned that 2008 sales were down 24% year over year.

The privately owned automaker still has $11 billion on hand, but Nardelli warned that if Congress doesn't approve a $25 billion loan, more job cuts and other cost cutting measures would be necessary. Chrysler also needs the federal loan to reach its goal of bringing just one of its three recently introduced EVs to market by the end of 2010.

This may not be the first effort at creating a Ferrari motorcycle, but it may very well be the best. Alfredo "Dino" Ferrari, the departed son of company founder Enzo, was said to have raced specially-prepared motorcycles in the 1950s. In the 1970s, Kay Engineering crafted a racing bike, now said to be worth half a million dollars, with full factory backing to honor Enzo Ferrari. In the '80s, legendary motorcycle designer Arlen Ness styled a one-off chopper on the Testarossa, while some guy named George crafted a pair of Ferrari-powered superbikes. Last year someone built a custom Scuderia Ferrari chopper for the retiring Michael Schumacher (who has since been trying his hand at motorbike racing), and earlier this year a collector crafted a model of what a Ferrari sportbike could look like. We're sure some more will be brought to our attention in the comments below, but while some of these creations have been more convincing than others, this one has to be the slickest.

The concept motorbike is the work of Israeli designer Amir Glinik, who centered his design around the theoretical application of the Ferrari Enzo's V12 engine, chopped down to four cylinders and modified to drive just one wheel in a motorcycle frame. Around the V4 engine, Glinik has designed a fluid shape that may appear more futuristic in its styling than inspired by current roadcar designs, but certainly catches your attention. Glinik has even planned out the theoretical controls, which blend elements from an F-16 fighter jet (more common in his home country than Ferraris, anyway) and the Scuderia's high-tech Formula One steering wheel, supplemented by a weatherproof touch-screen LCD atop the fuel tank.

Onetime Ferrari designer Frank Stephenson, now at arch-rival McLaren, was quoted as saying that the closest the average person will get to owning a Ferrari would be a Ducati. True as that may be, what you see here may be the most well thought-out and enticing application of the Ferrari ethos to two-wheeled motoring we've seen yet.

As reported recently, even though Toyota halted Tundra production for a while, the company pledged not to lay off its workers. At a total cost of potentially $1 billion to the company, Toyota instead placed the employees in retraining and civic works programs during a Kaizen and Development Period.

What kinds of civic programs? One of them, in San Antonio, is called the City-Toyota Green Clean-Up Project, which has put up to 340 workers on the streets to "clean, paint, and plant." Factory staffers have painted curbs, picnic tables and trash cans, trimmed trees and plants, and cleaned up lots. While employees do want to get back to the factories, they're enjoying the time away and being able to give back to the city -- all the while earning their regular wages and benefits.

A second round of city improvement will begin next month. After that, Toyota expects to have all hands on deck again at the factory in November, building 2009-model-year Tundras.

We can think of few better ways to spend our evenings than bending, welding and beating metal into submission to produce our own car and it seems that we are not alone. MAKE reader, Utah resident and Flickr user proximacentuari took the design of the Ariel Atom -- currently one of the most desirable track cars in existence -- and replicated it in his home garage. What's more, he documented the entire process with pictures and uploaded the whole thing to the internet. This is the coolest show-and-tell ever.

Powering the beast, known by its builder as z59, is a Honda K-Series four-cylinder engine from a wrecked Acura RSX. It's an impressive build, taking "15 months and at least 800 hours of work in the garage," all done without any official Ariel schematics. "The frame is completely custom. I didn't make a single measurement off the real car... what you see is a series of very educated guesses," according to the builder. Much of the car is made from scrap parts, including the bodywork from a number of old appliances, a kayak and a doghouse.

The Ford Falcon is all Australian. It has always been driven by the rear wheels, and it has always been designed, engineered, and built Down Under. The automotive world is rapidly changing, though, and Ford is one of many OEMs that are driving towards global vehicle architectures and a less diversified corporate parts bin. What does that mean for the Falcon? Nothing for quite a while, as the once hot-selling Aussie special just received major rework in April, and another redesign is many years away. When it does go under the engineering knife it will likely have more in common with the Ford Taurus than anything native to the Outback.

Ford product chief Derrick Kuzak is working towards what the Blue Oval calls "One Ford." That means, for example, that there will be only one C-segment platform for like-sized crossovers, wagons, hatchbacks, coupes, and sedans, and that platform would be used in all regions around the globe. Ford will still have a rear-drive platform for performance vehicles, but the rabid push for fuel efficiency and weight reductions means that the chance of future Falcons being motivated by the rear wheels is slim. Plenty can change between now and 2015, so we'll keep our dimming hopes for a RWD Falcon for all alive, but the prospects look less rosy by the day.
