Vexing Hex: Iranian Designer Pens 6-Wheel Mercedes-Benz Off-Roader

For now, the Unimog remains Mercedes-Benz’s most potent off-road machine -- but we rather like the ideas presented in the design concept crafted by Iranian engineer Siyamak Rouhi Dehkordi.

Dubbed the Mercedes-Benz Hexawheel, the conceptual off-roader utilizes -- of all things -- six wheels. The hallowed portal axles of the Unimog are abandoned in favor of independent suspension at each wheel, but the frame itself is truly interesting.


Like the unusual M561 Gamma Goat military vehicle, the Hexawheel sports a vertically articulated frame, which is hinged around the axis of the center pair of wheels. Dehkordi says the design allows for substantial vertical articulation -- the frame can theoretically travel 28 degrees up and 30 degrees down. A pair of hydraulic rams controls the articulation, provides dampening, and in some instances, work to help push the Hexawheel over large obstacles.

Unlike the Goat, which sported steering on its front and rear axles, the Hexawheel’s rear trailer pivots side-to-side, allowing the 16-foot long vehicle to have an 18-foot turning radius. Further enhancing its prowess off-road is its balanced drivetrain. Dehkordi’s design calls for a diesel-hydraulic drive system, with the engine, pump, and accumulators placed underneath the pickup bed. The fuel tank, located under the cab, helps distribute truck’s 4850-pound curb weight.
We think this is a neat design -- but our only reservation lies with torsion. Long-travel suspension does help traverse obstacles, but when it comes time to twist -- like the Gama Goat does when climbing this hill -- we’d be curious to see how the Hexawheel performs in the real world. Sadly, we think this will remain a digital flight of fancy for the foreseeable future.

Return of tii? BMW Executive Confirms Hotter 1 Series

BMW’s high-performance 1 Series has been spied undergoing development, but no one at the company had actually confirmed the car -- until today. Dr. Kay Segler, president of BMW’s M Division, confirmed BMW’s plans for the car and that it won’t share the M1 name of BMW’s legendary supercar.
Though the M1 name won’t be coming back, we don’t yet know exactly what this car will be called. A number of different names are possible -- 135is, given BMW’s current naming scheme, the 1 Series M, as it is being developed by the Motorsport Division, or even the early return of the tii badge. We saw the 1 Series tii Concept in 2007 and reported that the vaunted tii badge would be coming back in 2011, could this car be it?

Whatever the name may be, the car will have some serious performance credentials. Segler revealed to Autocar that it will produce around 350 horsepower and in excess of 310 pound-feet of torque. Power will come from an M-tuned version of BMW’s outgoing N54 twin-turbocharged, 3.0-liter I-6. Autocar reports that it is likely to use BMW’s seven-speed dual-clutch transmission, but we’re hoping a six-speed manual is available as well.

In order to help the more potent 1 Series put the power to the ground, BMW’s M Division is adding an electronically controlled M differential and also reworking the car’s suspension. The 1 Series’ typical suspension layout remains, MacPherson struts in front with a multi-link rear, but with stiffer springs and dampers and a different set of bushings. In addition to helping the car get better traction, the suspension changes should also improve the car’s handling.

In this time and age, even a product from BMW’s M Division couldn’t escape the political pressure to reduce consumption and emissions. BMW’s Efficient Dynamics systems are likely to appear on the car with features such as regenerative braking and possibly even a start-stop system. These features will reportedly keep the high-performance 1 Series’ fuel economy about the same as a regular 135i -- 20 mpg combined in the U.S.

BMW’s high-performance 1 Series will reportedly go on sale in Europe next year. It is likely to make its way to the States sometime next year as well. It will slot in above the 135i and below the M3 coupe with pricing likely to start somewhere in the mid- to high-$40,000 range. Stay tuned for details as the car’s launch gets closer.

Spyker Set to Sell its Cars in Select Saab Showrooms

Spyker had promised to keep its chocolate discrete from Saab's peanut butter, but it appears Saab's new corporate parent may soon sell its high-end sports cars in Saab showrooms.

"We are signing up Spyker dealerships left, right, and center," Spyker CEO Victor Muller recently told Bloomberg.


Presently, Spyker has only 35 retail outlets across the globe, but that will soon change. Spyker plans on offering its wares -- including the new C8 Aileron -- through a number of select Saab dealerships. Spyker hopes to nearly double its sales network to 60 outlets by the end of this year, and bump that total to 90 by the end of 2011. Doing so may help Spyker move more than the 36 vehicles it sold in 2009.

Adding Spyker models to Saab showrooms will be a big change for most dealers, as pricing and clientele tied to Spyker cars are quite different from that of Saab vehicles. A 2010 Spyker C8 Aileron costs $219,190, while Saab's new 9-5 Aero -- the most expensive Saab model at this time -- starts at $49,990.

Still, every extra dealer helps -- and the extra showrooms are but one of the many Saab resources Spyker hopes to utilize to its benefit. The automaker has previously mentioned using Saab's engineering staff and resources (including the company's wind tunnel laboratory in Trollhattan, Sweden) for new vehicles, and may benefit from lower prices on generic parts that can be used Spyker and Saab models. Muller hopes these moves will help Spyker turn a profit -- something it hasn't done since going public in 2004.

"Spyker will be profitable in its own right, very much helped by its sister Saab," said Muller. "It's wonderful that the company that saved Saab is also benefiting from having done that in its own business."

Helio Castroneves Takes his Fourth Indy 500 Pole

The 2010 Indianapolis 500 won’t start until May 30, but as is so often the case with motorsports events, the action isn’t relegated to one weekend -- or, for that matter, one day. Pole Day -- the official qualifying day for the 500 -- was this past Saturday, and determined the starting order for the 500.

After besting his 2009 qualifying speed by over 3 mph, Helio Castroneves will sit in the pole position once again -- and be the first back-top-back Indy 500 pole-sitter since Scott Brayton’s performances in 1995 and 1996. Castroneves earned the position -- his fourth pole qualification at Indy -- by lapping the 2.5-mile track at 227.970 mph (in 2009, his grid-topping speed was 224.864 mph).

Before snagging the lead starting position, Castroneves held second behind Alex Tagliani. With just an hour and a half left in qualifying, Team Penske withdrew Castroneves’ time for a chance to snag the top position. It paid off -- although he had to sit through a tense 90 minutes as he watched other drivers approach his speed.

“Sitting in that car for an hour and a half was not easy at all, especially with everyone getting closer and closer,” said Castroneves. “I was like, ‘Are we going or not?’ because I can’t handle that much pressure.”

At the end of the day, only Castroneves and teammate Will Power (227.578 mph) posted speeds above 227 mph. Ryan Briscoe, Team Penske’s third driver, will start in fourth place, just behind Dario Franchitti. Tagliani -- who once looked to be the front-runner for pole position -- will start the race from fifth place. Scott Dixon, Graham Rahal, Ed Carpenter, and Hideki Mutoh round out the first three rows respectively.

There are some notable absentees from the top nine positions. Ryan Hunter Reay, who currently sits fourth in points in the 2010 IndyCar series, will start the race from the 17th position, while 2008 Indy 500 winner Dan Wheldon will start in 18th place. Danica Patrick will start the race in 23rd place, attributing her dismal qualification to “one of the worst” cars she’s ever driven. Regardless, she did better than 2004 IndyCar champion Tony Kanaan, who crashed twice in 24 hours exiting Turn One. It’s rather miraculous that the Andretti Motorsports team was able to restore his car for yesterday’s Bump Day, which allowed him to earn a 32nd-place starting position, just shy of last place.

Will Castroneves become the fourth driver to win the Indy 500 four times, and earn back-to-back wins from a pole starting position? We’ll know this Sunday after the checkered flag drops at Indy. Look for the race to start at 1:15 p.m. (EST) on Sunday.
