There are some pretty incredible pickup trucks that you can buy in the United States, such as the Ford F-650. However, few can hold a candle to this 2004 Mercedes-Benz Unimog U500 featured in a recent video from Doug DeMuro and listed up for auction.

This particular Unimog has been registered in the United States since at least 2012 and comes outfitted with a 6.4-liter turbocharged inline-six diesel rated at 260 hp and a monumental 700 lb-ft (950 Nm) of torque. This engine works alongside a four-wheel drive system, an 8-speed automated pre-selector manual transmission and a two-speed 4WD transfer case.

As revealed by DeMuro during his review, it was modified back in 2015 and fitted with a crew cab and a three-way tilting dump bed complete with a custom-built rollover bar and spare tire mount.

Stepping inside reveals an interior unlike any other Mercedes-Benz model. There is a massive windshield that provides you with superb visibility and large windows on the front doors that eliminate any potential front blind spot. There are also three seats in the front row and the driver’s seat has its own suspension system to add some comfort.

There are a few details related to this particular Unimog that prospective customers should be aware of, as revealed by the Cars & Bids listing. For example, the Carfax report shows that it was overturned in 2004 but doesn’t provide any more details. There are also some scratches on the cab and the driver’s seat belt buckle doesn’t work.

However, if you’re looking for a capable off-roader that you can use to traverse continents, this could be it.

 


While recent generations of the Corvette have significant performance advantages over their predecessors, many still prefer the looks of the originals, in particular the C2 and C3 models. For those people, this 1968 restomod could be the perfect car.

Heading to auction on January 7-16, this C3 Chevrolet Corvette has been outfitted with a host of modern modifications that should have a transformative impact on the way it drives.

Underpinning the car is a reinforced Street Shop chassis that includes fully independent suspension from a C7 model. The real highlight of the car is the fact that it has been fitted with GM’s 7.0-liter LS7 V8 that pumps out 505 hp and is coupled to a T6 six-speed transmission driving the rear wheels. While the Mecum Auctions listing doesn’t provide any performance details, the car should probably keep pace with a C7 Stingray in a straight line.

The modified C3 has the same big brake kit as a 2018 C7 Z06, is painted in the same shade of Mosaic Black which was offered for the C7 Z06, and is sitting on Asanti three-piece carbon fiber wheels that measure 20×9 at the front and 20×13 at the rear. Moreover, the car also sports a full-leather interior with orange contrast stitching and orange seat belts.

The auction house expects the Corvette C3 restomod to sell for $200,000-$235,000.

Ever since its inception, Formula 1 has always been the premiere level of motorsport, and as such, the cars that race in it are some of the most technologically advanced on the planet. That being said, what was advanced 50 years ago is not so advanced by modern standards, and we can perform a good comparison by looking at the engines.

The comparison was first brought up on Twitter by Matt Grant, co-owner of Cosworth parts supplier Modatek.

Pictured below are two Formula 1 engine blocks from Cosworth, about 50 years apart. The one on the right is from a 1967 Cosworth DFV (double four valve) 3.0L V8 and the one on the left is from a 2013 Cosworth CA 2.4L V8.

The DFV is one of the most famous F1 engines of all time, powering many iconic cars in the history of the sport. The 90-degree V8 won its first race in 1967 with Jim Clark, and went on to win 155 more until the end of its run in 1983 with Keke Rosberg.

By contrast, the CA might not have been as much of a winning machine as the DFV, but it was still a good engine and allowed many smaller teams, who had restricted finances, to partake in the sport. What the CA’s true claim to fame was, however, was it being the last V8 in F1, since the series made the switch to a V6 hybrid system in 2014.

If we look at the two engines, we can see all the technological progress that has been made in the 46 years that separate them. The first thing you’ll notice right away is the size difference, despite the CA only being 0.6L smaller than the DFV. Thanks to Computer Aided Design (CAD) and Computer Numerical Control (CNC) machining we are able to manufacture much more advanced, efficient designs compared to what was possible nearly half a century ago.

If we look at the piston heads of the two engines below, we can see a similar size difference between them as we did with the engine blocks. Again, the 2013 CA’s piston heads are able to be so much smaller and lighter than the 1967 DFV’s without sacrificing strength due to all the advancements made in manufacturing processes and materials.

And even since 2013, F1’s scientists and engineers have made huge strides in power unit technology and efficiency, now having the hybrid system to deal with in addition to the engine. For example, some of the current F1 engines are able to operate at 50 percent thermal efficiency, which means that 50% of the engine’s fuel is converted into propulsion force and the other 50 percent is lost as heat. That might not sound great, until you realize that a regular road car’s engine operates at a thermal efficiency of around 30 percent. That’s only one of so many advancements made since then, and more are being made every single day.
