Chrysler Shows 8300cc V10, 500-horsepower Tomahawk Concept Motorcycle--Or Maybe It's An ATV--At Detroit Auto Show

From a press release issued by the Chrysler Group of Daimler-Chrysler:<BR><BR><img src="../issues/jan03/chrysler1.jpg"><BR><BR>Dodge Tomahawk: Breaking Boundaries at Full Throttle <BR><BR>Life just got more extreme. Much more extreme.<BR><BR>The Viper-powered Dodge Tomahawk concept vehicle shatters all the barriers of conventional thinking about personal transportation. This four-wheel, single-passenger vehicle is a sleek, rolling sculpture that combines art-deco styling with extreme engineering.<BR><BR><img src="../issues/jan03/chrysler2.jpg"><BR><BR>The 500-horsepower Viper V-10 engine powering the dual rear wheels gives this radical vehicle a potential top speed of nearly 400 miles per hour – for anyone who wants to test it. The Tomahawk roared into public view at the North American International Auto Show.<BR><BR><img src="../issues/jan03/chrysler3.jpg"><BR><BR>"The Dodge brand philosophy always challenges us to grab life by the horns," said Trevor Creed, Senior Vice President – Design, Chrysler Group. "In the case of Tomahawk, grabbing and holding onto anything for dear life is a necessity. It's just that extreme and passionate; a glimpse into the soul and commitment of true enthusiasts."<BR><BR>Initial reaction to the concept vehicle typically comes in two words: "Wow" and "why."<BR><BR>The "wow" is easy to understand from Dodge, the brand that continues to drive its foot to the floor - most recently with the all-new 2003 Viper, Heavy Duty and Light Duty Rams and an SRT lineup dedicated to engineering the most powerful production vehicles in their segments. <BR><BR>But "why" would a company, famous for its innovative car and truck designs, go down this particular path?<BR><BR>"Tomahawk is an icon of the extreme thinking for a brand that is known not only for the legendary Viper and Ram, but also for all new, innovative vehicles such as the Magnum SRT-8 and Durango concepts," said Creed.<BR><BR><img src="../issues/jan03/chrysler4.jpg"><BR><BR>That extreme thinking produced a machine in the true tradition of power-junkie passion, powered by a 505 cu. in., 8300 cc aluminum Viper V-10 engine. <BR><BR>"This is a bold faced slap against mediocrity," Creed said. "Tomahawk is a scintillating example of what creative minds can do when given the opportunity to run free. It is a pure mechanical sculpture and a joyous celebration of the artistry and emotion of design."<BR><BR>The Dodge Tomahawk is a Chrysler Group design concept that is as much a Viper-powered work of art as it is a whole new type of vehicle invention. It is both a sculpture that can be ridden, as well as a bold statement about the Chrysler Group's enthusiast culture and passion for design.<BR><BR>"Tomahawk moves design concept introductions and the concept car game to a whole new level – as only Dodge and the Chrysler Group can," said Creed.<BR><BR>DODGE TOMAHAWK CONCEPT VEHICLE SPECIFICATIONS<BR><BR>GENERAL INFORMATION<BR><BR>Body Style: Single-seat Viper-powered motorcycle concept vehicle<BR><BR>DIMENSIONS:<BR><BR>Overall Length: 102 inches<BR>Overall Width: 27.7 inches<BR>Overall Height: 36.9 inches<BR>Wheelbase: 76 inches<BR>Seat Height: 29 inches<BR>Curb Weight: 1,500 lbs.<BR>Track, Front: 8.75 inches<BR>Track, Rear: 10 inches<BR>Weight Dist., % F/R: 49/51<BR>Ground Clearance: 3 inches<BR>Fuel Tank Capacity: 3.25 gallons<BR><BR>ENGINE: 8.3-LITER, OHV, 20-VALVE SMPI V-10<BR><BR>Type and Description: 10-cylinder 90-degree V-type, liquid-cooled<BR>Displacement: 505 cubic inches (8277 cc)<BR>Construction: 356-T6 aluminum alloy block with cast-iron liners, aluminum alloy cylinder heads<BR>Bore x Stroke: 4.03 inches x 3.96 inches (102.4 x 100.6)<BR>Valve System: Two pushrod-actuated overhead valves per cylinder with roller-type hydraulic lifters<BR>Fuel Injection:Sequential, multi-port electronic with individual runners<BR>Compression Ratio: 9.6:1<BR>Power (SAE net): 500 bhp (372 kW) @ 5600 rpm (60.4 bhp/liter)<BR>Torque (SAE net): 525 lb.-ft.
