We drive the 2016 Ford F-750 Tonka dump truck

The Ford F-750 dump truck stands nearly 10 feet tall and is painted bright yellow. It idles patiently yards away from Ford's test track in Dearborn, MI. "Tonka" is emblazoned on the sides. We pose the obvious question to Ford marketing manager Mark Lowrey: Why do this? "We built this truck to get attention," he replies. And indeed it does. Ford revealed the 2016 F-750 Tonka dump truck in March at an industry show, underscoring that the Blue Oval is back in the business of big trucks after years of teaming with Navistar in a joint venture. The new F-650s and F-750s start rolling off the line at a factory near Cleveland this summer, and the order bank is open now. The trucks come in regular, super, and crew cabs and offer three states of tune for the 6.7-liter Power Stroke V8 turbo diesel, plus a gasoline-fed 6.8-liter V10. Naturally, the Tonka has most powerful diesel mill, with 330 horsepower and 725 pound-feet of torque. The Tonka edition is a paint-and-sticker one-off that Ford is using as a promotional tool. You can't buy one, and it will be touring shows and events throughout the year. Lowrey notes that it calls attention to work trucks in a positive way. The general public usually only sees them when the trucks are blocking the road or making too much noise at a construction site. Tonka trucks, on the other hand, conjure up happy childhood memories. "We're going to do something where someone's going to see this truck and smile," he says. It's hard not to grin as we climb into the cabin of this monster truck. It has a 33,000-pound gross vehicle weight rating and can carry five yards worth of dirt. We're not doing anything like that today – just puttering around Ford's handling circuit inside its product enclave. The course is closed, so even though this track is better suited to calibrating Mustangs, F-150s, and well, almost anything but a dump truck, we're totally relaxed. We depress the button to release the parking brake and are off. The truck is surprisingly easy to drive. The vision ahead is excellent – makes sense, we're nearly one story off the ground, after all. The cabin is simple and cleanly laid out. It looks like a Ford truck, regardless of the size. The diesel engine has a lot of grunt. We can feel the torque. The steering is light, and we have to stomp on the air brakes to slow this thing down. We go 'hot' into a tight corner just for fun. It's not really that fast, but it raises the eyebrows of our film crew, which is set up nearby.

Shelby GT350R offers first mass-produced carbon fiber wheels

In the world of race engineering, reducing total weight is good, but reducing unsprung weight is flippin' fantastic. That's the reason Ford is pushing the envelope in terms of technology for the Shelby GT350R's wheels. Joining the likes of Koenigsegg in the offering, Ford has teamed with Australian outfit Carbon Revolution to produce the CF rollers en masse for the first time. Destined for the hubs of the new Shelby GT350R, the new hoops weigh just 18 pounds each, versus the 33-lbs weight of a similar aluminum wheel. On top of slashing up to 60 pounds in unsprung weight, there's such a reduction in rotational inertia – 40 percent, versus aluminum wheels – that Ford actually has to recalibrate the magnetic ride control system and springs. Thanks to, we're guessing, scenes of crashed Formula One cars disintegrating and spewing shards of carbon fiber all over the track, Ford seems quite keen to do away with the idea that CF is strong, but brittle. The company conducted extensive shock testing, ramming a wheel into a curb at speed. According to the Blue Oval, the lightweight wheel allowed the suspension to respond so quickly that the impact was "greatly diminished," causing the tester to run the experiment again, thinking there'd been a mistake. After recording brake rotor temperatures of 900 degrees Celsius (over 1,650 degrees Fahrenheit, or well past the point that aluminum or magnesium would melt) during testing, Ford and Carbon Revolution actually redesigned the wheels to "a thermal standard more suitable for motorsports," by adding an "incredibly thin, nearly diamond-hard coating that reliably shields the resin from heat." The same process was used to protect engine turbine blades on the Space Shuttle. While the work by Ford and Carbon Revolution should make GT350R customers excited, the work being done here could have serious implications for performance cars in the future. That's the real takeaway here, and is something that should leave fans of all performance vehicles excited.

2023 Grand National Roadster Show Mega Photo Gallery | Hot rod heaven

POMONA, Calif. — From an outsider's perspective, it would be easy to assume that the Grand National Roadster Show has always been a Southern California institution. After all, it celebrates the diverse postwar car culture of the region — hot rods, lead sleds, lowriders, and more. However, the show had its roots in NorCal in 1950 when Al Slonaker and his hot rod club showed their custom cars at the Oakland Expo. The GNRS moved to Pomona, California, in 2004. By then it had grown exponentially and seen about a dozen more car customization trends come and go. However, the show and its centerpiece award, the America's Most Beautiful Roadster prize, celebrate what is perhaps the first of those trends: the American hot rod in its purest form. Today, in its 73rd year, the GNRS is the oldest indoor car show in America. Annually it welcomes 500-800 cars, gathered into special themes like Tri-Five Chevys or Volkswagen Bugs. At this year's show, which was last weekend, a special hall was dedicated to pickup trucks built between 1948-98, including mini-trucks, groovy camper bed conversions, and resto-mods.  However, of all the vehicles presented, only nine are eligible for the America's Most Beautiful Roadster award. Winners get their names engraved on a 9-foot-tall perpetual trophy that was, according to The Ultimate Hot Rod Dictionary, the largest in the world when it debuted in 1950. Slonaker chose the word "roadster" initially because "hot rod" bore slightly negative outlaw connotations in 1950. Only American cars built before 1937 of certain body styles — roadsters, roadster pickups, phaetons, touring cars — are eligible, and they cannot have roll-down side windows.  Cars in the running for the cup cannot have been shown anywhere else before their debut at the GNRS.  Contestants for this accolade essentially build their cars to the a platonic ideal of a hot rod. This year the honors went to Jack Chisenhall of San Antonio, Texas, for his "Champ Deuce," a 1932 Ford Roadster. It's exactly what you picture when you think of a hot rod, but distilled to its absolute essence.  Other standouts included "Green Eyes," a two-tone green 1959 Chevy El Camino  with a heavily metal-flaked bed, "Blue Monday," a 1964 Buick Riviera lowrider, and a personal favorite, "Purple Reign," a purple and black 1951 Mercury. Cars may have started out as tools, but there aren't shows like this filled with custom refrigerators.
