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.

Shocking footage has surfaced online showing the moment a massive semi-truck side-swiped a Tesla Model 3 in the U.S. last year.

This video was recently posted to the Wham Baam Teslacam channel on YouTube and reveals that the incident occurred on a tollway in Colorado. While the truck driver was to blame for the crash, it could have been easily avoided.

As the front-facing camera of the Tesla reveals, it was approaching a large semi-truck in the right lane. Suddenly, however, the trucker merged into the lane being occupied by the Tesla. The truck slams into the side of the Model 3, shattering its passenger-side windows and sending it into the median where its driver, Aaron Smith, managed to swerve around the cable barriers before coming to a stop.

Images taken of the Tesla after the crash show that both the passenger side doors were scratched and dented heavily by the truck. The passenger-side front wheel was also ruined, as was the front bumper. Unsurprisingly, the narrator of this video says that the Tesla was determined to be a total loss.

Could the crash have been avoided? Yes. If you re-watch the clip, you’ll notice that the trucker had his turn signal on and was looking to change into the left lan, so perhaps the Tesla driver could have backed off the throttle to let the truck in. Not that this is any excuse for the truck driver, who should have taken much more care when changing into the left lane. Had they looked in their mirrors, they would have seen the approaching Model 3.

 

At the time of its introduction, the Porsche Carrera GT was the finest, road-legal supercar the German automaker had ever created. It was an instant classic and yet despite being applauded by pundits, famed German tuning company Gemballa thought it could do better. The result was the Mirage GT.

Just 25 examples of the Mirage GT have been produced over the years with owners given the ability to spec out each car to their personal tastes, whatever they may be. The example featured is one of the more aggressive cars built and is currently up for sale.

Listed through Alain Class Motors in Dubai, widely regarded as one of the premier supercar/hypercar dealerships in the world, this Mirage GT is adorned in a shade of matte black and complemented by a host of red accents, including the outer edges of the wheels, brake calipers, headlights, and engine cover. Porsche enthusiasts may hate it but it’s certainly one way to stand out, even in Dubai.

In creating the Mirage GT, Gemballa transformed the exterior, developing new front and rear fascias while also adding distinctive side skirts, an enlarged rear wing, and a bespoke engine cover. Modifications continue in the cabin with this car sporting red leather across the seats, steering wheel, and parts of the door panels. The cabin also features areas of exposed carbon fiber and black leather.

Gemballa opted against messing with the Carrera GT’s beloved 5.7-liter V10 engine and only fitted it with a new exhaust system that boosts power up to 645 hp.

No pricing details for this Mirage GT have been provided in the listing, but that kind of tells you something about what it’ll cost you, doesn’t it…
