At 9AM Eastern on Monday morning, a fleet of 23 diesel-powered Audis will roll out from Manhattan's Tavern on the Green on a trans-continental trek to demonstrate diesel efficiency. I'm in Manhattan this afternoon preparing to spend the next week in an Audi Q7 TDI on the way to Denver and will be checking in regularly from the road as we pass through Washington, Cleveland, Chicago, Memphis, Dallas and Amarillo along the way. Audi plans to launch its fifty-state-legal Q7 TDI in the US market next spring and it seems likely that some of the other vehicles on this trip may not be far behind.

I'll be on the first two legs and Sebastian, Damon, Drew and Jonathan will take over for the second week of the trip to Los Angeles. You can also follow along at the Audi Mileage Marathon site where there's a Twitter feed following the participants as they cross the continent. There is also a live map showing our location on the road along with two blogs, including one from Audi of America boss Johan de Nysschen. Twitter users can follow audimarathon to see what some of the 200 participating journalists are saying.

They say you get what you pay for. Unfortunately, even with the second release of the Audi A4 Driving Challenge for your iPhone or iPod Touch, the price tag is still fairly representative of the quality of the game. According to Audi, 370,000 people downloaded version 1.0, but we'd be curious to know how many of those copies were still on the devices 48 hours after the user first tried it out. Our guess would be not many. Version 2.0 is certainly much improved. Audi has added new vehicles that can be unlocked, including the A4 3.2 and the mighty R8.

The graphics are also better, compared to the original. Unfortunately, like so many other games on other platforms, graphics and good features don't necessarily equate to great gameplay. Compared to Crash Kart, the vehicles in this Audi game are hard to control, and the game simply isn't much fun because the scale speeds are so slow. Since it's free, go ahead and download the Audi A4 Driving Challenge and try it yourself. Thankfully, not all of the free apps on the iPhone and iPod Touch are of the same quality of this one. Perhaps for v3.0, Audi should hire someone with more experience in driving game design.

Peugeot has been showing diesel hybrid concepts at auto shows for the past several years, and the latest is the new Prologue HYmotion4. Unlike the previous versions that were based on the 307 and 308 C-segment hatchbacks, the Prologue is an all-new vehicle. Also unlike the previous concepts that used a hybrid system where the engine and electric motor ran in parallel on the same axle, this one uses the company's new HYmotion4 system like the RC concept we showed you earlier today. And unlike the four-door coupe RC, the crossover-bodied Prologue flips the powertrain arrangement front to back. The CUV has a 163-hp 2.0L four-cylinder turbodiesel twisting the front wheels while a 27 kW motor sends torque to the rear axle. The combined output when both the diesel and motor are running is 200 hp with 221 lb-ft going to the front wheels and 148 lb-ft to the back. Like the RC concept, front-, rear- and all-wheel-drive modes are available. Since rear-drive is electric only and the motor output only 27 kW, that mode is only available up to 30 mph. The diesel engine up front sends power through an automated 6-speed manual gearbox that allows for manual shifting. Peugeot also claims the electric motor is activated during shifts to provide uninterrupted power flow and smoother operation. Whereas the RC concept uses lithium-ion batteries, the Prologue uses a cheaper nickel-metal hydride battery pack sitting under the rear seat. Altogether, the Prologue is claimed to achieve 57.4 mpg (U.S.) with carbon dioxide output of 109 g/km.

The RC HYmotion4 concept is one of several hybrid concepts using a new through-the-road hybrid system being shown in Paris by Peugeot and Citroen. Unlike the hybrid systems used by current production vehicles, this one has no direct mechanical connection between the electric and internal combustion drive systems. The Peugeot RC has a turbocharged 1.6L four-cylinder in the back driving the rear wheels with 218 hp and 206 lb-ft of torque, while additional propulsion comes from a 70 kW electric motor situated between the front wheels. This way, the RC can operate in either rear-, front- or all-wheel-drive modes. That means it can also operate using internal combustion, electric only or blended modes, respectively. The 3,141-lb four-door coupe accelerates from 0-62 mph in just four seconds when both gasoline and electricity are flowing. The electrons are stored in a lithium-ion battery pack of indeterminate size, but having the electric motor at the front instead of the rear axle means that more kinetic energy can be recaptured through regenerative braking. According to Peugeot, the RC can get 52.3 mpg and output CO2 emissions of just 109 g/km. It's a trick system for sure, but there's no word on whether it's ever going to be produced.

Pininfarina is the Italian design studio perhaps best known for penning almost every production Ferrari over the last half century. The firm, however, does much more than just design exotic sports cars. It has created bodies for more mainstream cars like Peugeots, Alfa Romeos and even Daewoos. The company's latest creation is a compact four-seat hatchback propelled by electrons. Pininfarina has formed a joint venture with French battery maker Bolloré to build this electric car.

The B0 uses a hybrid energy storage solution consisting of a 30 kWh lithium-polymer battery and a bank of super-capacitors. While the capacitors have very limited storage capacity, they can absorb and release energy much faster than a battery. That way more regenerative braking can be used and a bigger performance boost is available. Pininfarina hopes to start limited production late in 2009, ramping up volumes as batteries become more available and presumably affordable. The battery pack itself is claimed to have a lifespan of 125,000 miles. A single charge is expected to deliver 153 miles of driving with a maximum speed of 80 mph. Helping to extend the range a bit are solar cells in the roof and on the nose in the area that looks like a grille.

Speculation about Ferrari building a sedan has repeatedly cropped up over the past couple decades, and Ferrari denies it every time it does. As Aston Martin, Porsche and now Lamborghini have been working on four-door cars lately, the idea that Ferrari might has gained even more traction. It looks like the Sultan of Brunei will have to continue relying on Pininfarina and other coach builders for his four-door Ferraris. Today in Paris, Ferrari president Luca di Montezemolo applied full carbon brakes to that theory as he stated in no uncertain terms that as long as he was holding the top office at the sports car maker, "We will never do a four-door." Wtih Ferrari selling its sports cars and GTs as fast as they can be built, Montezemolo is content to let corporate sibling Maserati handle the task of building exotic Italian four-doors.

While Ferrari owners are by definition people of considerable means, they and the company are still not immune to modern realities when it comes to both fuel prices and environmental regulation. At this years Detroit Auto Show, Ferrari displayed an F430 Spyder that could run on E85 ethanol. Similarly, the F1 side of the house is currently developing a kinetic energy recovery (KERS) hybrid drive system that, like current semi-automatic transmissions, could migrate to production vehicles. According to Montezemolo, Ferrari will not be building a V10 engine either as an upgrade to the V8 or downgrade from the V12.

Engineer Bob Kearns had been granted a patent for a design of intermittent windshield wipers in 1967, two years before Ford introduced them in production. Unfortunately for Kearns, Ford had "developed" its own system rather than licensing Kearns' design. Needless to say, litigation ensued and it took until 1995 for the U.S. Supreme Court to finally rule against Ford and Chrysler and award Kearns $30 million. That story has now been turned into a major motion picture being released this week called Flash of Genius, and Ford wants you to know that the facts of the matter are much less dramatic than what the movie portrays.

While reminding people that the facts have been dramatized, Ford also mentions that a jury ruled it did not "willfully" infringe on Kearns' patent. That's not to say Ford and Chrysler didn't infringe – juries ruled that they did. It just wasn't "willful." Did Kearns ultimately win? That's hard to say considering how his life turned out, but he was vindicated. On the other hand, many owners of older English cars would argue that Joseph Lucas invented the intermittent windshield wiper, although again not willfully.

The trickle of images from Sant'Agata continues today as Lamborghini has shipped yet another teaser of the new car that it will show on Thursday at the Paris Motor Show. This time around we get a frontal image of the headlight area. Unlike the last two production models, the Gallardo and Murcielago, the orientation of the light cluster has been switched from vertical to horizontal. There is also a large vent visible implying that the engine is up front this time around. We only have one more day to wait for the full reveal, so it will be interesting to see what Lamborghini has wrought when it unveils the Urus or Estoque or whatever this concept turns out to be named.

The ultimate Aston Martin is only a year old, but it's already getting some updates including a new automatic transmission. The DBS will receive an optional automatic transmission dubbed the TouchTronic 2 for the 2009 model year, a re-engineered version of the ZF six-speed unit equipped in the DB9. Given the DBS' more harder attitude over the DB9, the transmission has been tuned for faster, more aggressive shifts in order to maintain the same acceleration capabilities as the manual transmission version and giving drivers the choice of swapping their own cogs via steering wheel-mounted paddle shifters. When the situation is more relaxed the driver can enjoy some tunes over the new 1,000-watt Bang & Olufsen stereo system. For those inclined to occasionally punish a couple of friends, Aston is now offering a pair of +2 rear seats. The company claims this is at the request of customers, but frankly, customers who make such silly requests should probably be sent elsewhere anyway. The automatic DBS commands a $4,000 premium over the three pedal variant and starts at $273,000.

As the era of the Mercedes McLaren SLR winds down to its conclusion sometime in 2009, Mercedes-Benz is releasing what may be the ultimate example of the breed. The SLR 722 S Roadster picks up where the 722 coupe left off dropping the 650-hp supercharged 5.5L V8 into the open top body shell. With a top speed of 220.6 mph, this may be the fastest open top production car ever built. And unlike the first generation Dodge Viper, Mercedes has devised a soft top that can withstand sustained 200 mph+ top speeds. Mercedes has tapped into McLaren's F1 experience to create the fully carbon-fiber body that can provide the structural integrity needed at those speeds. The semi-automatic top just needs to be unlatched from the windshield header manually before the rest of the process is handled by the electrical actuators. The vehicle dynamics are also aided by dropping the suspension by 10 mm at each end of the car and recalibrating the spring and damper rates. Only 150 examples of the 722 S Roadster will be made available starting Jan. 1 2009.
