Watch divers pull 1973 Ford Mustang Mach 1, Mazda RX-7 from a river

It’s like the ultimate barn find, only swap out the relatively ideal dry confines of a barn for a watery grave. Adventures with Purpose, a YouTube channel devoted to the exploits of a group of divers in Oregon that specializes in pulling submerged cars from the water, recently found six vehicles in the Tualatin River, near Portland. The most notable finds? A 1973 Ford Mustang Mach 1 fastback and a Mazda RX-7 sports car, plus a Chevrolet LUV pickup, which is not shown being pulled from the water. As you might expect, neither are exactly in top condition, with the badly rusted Mustang basically disintegrating into scrap pieces as itÂ’s pulled onto a flatbed truck parked on a boat ramp. The RX-7, meanwhile, is caked with mud, its windshield and roof crumpled, but itÂ’s basically intact. A hat tip goes to CarBuzz for spotting the videos. The divers use inflatable salvage bags to help raise the vehicles. They removed the MustangÂ’s rusted and encrusted V8 first — the '73 model came with either 302 or 351 engines — and had to pause to remove some of the thick mud that had built up inside the car. Other things they found from both pulls include an old sledgehammer, a stop sign and a rusted Washington state license plate. This content is hosted by a third party.

The whole Mach 1 salvage operation took two days. “A lot of you are going to be a bit upset at how destroyed the Mustang Mach 1 became after we tried removing it from the river,” the team wrote in its description. “In our defense, there was an extra 8,000 pounds of mud inside the car, along with the Mustang being underwater in the river for over 40 years.” The Adventures with Purpose team says it has recovered 326 cars, six guns, two bodies and a tractor, among things.

Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.

Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.
