Check out Aston Martin's zero-emissions AMR-SB race car

In the above video, Aston Martin reveals its AMR-SB race car. According to the chassis designer, it came at a time that was fairly busy, especially following the company's Le Mans class victory. But they saw it through, and the result is an amazingly light, zero-emissions race car. Aston was able to do this by powering it with the constantly present resource of gravity. Yes, it's a soapbox derby car. We appreciate car companies that have a sense of humor, and that's clearly what Aston demonstrates with this professional intro video for its soapbox racer. The company built it for the Red Bull Soapbox race in England, and it looks just like one of Aston Martin's Vantage GTE Le Mans racers, down to the wing on the back. That wing didn't seem to be attached quite as well as those on the real cars, since it disappears after one of the jumps. The car gets going more quickly than you might expect, too, as the video shows it hitting over 30 mph at a certain point. Check out the fun in the video above. You can also see the whole ride down from the driver's view in the video below. Related Video:

Episode 2 of The Grand Tour will feature knives, explosions, guns, and also cars

Following an immensely successful debut, The Grand Tour will follow up its first episode with exciting, dangerous things. Based on the trailer above, the episode will start peacefully enough with the trio driving up to the tent in South Africa with a convoy of off-road trucks. However, it seems each segment will be much more exciting. Right at the start of the trailer, there are clips of the Aston Martin Vulcan, a 7.0-liter, 820-horsepower V12 supercar, which will likely be the car tested at the "Ebola-drome" this week. Of course the car is communist because it doesn't have a V8. Then things get steadily more dangerous through the trailer. James May is shown as a somewhat unwilling participant at some sort of drifting exhibition. He apparently doesn't like tire smoke in the evenings. We also see that the trio went to Jordan for another segment. This is when we get a glimpse of Richard Hammond playing with large knives. Immediately following are clips of some sort of car chase challenge with large SUVs and luxury sedans, during which James May shoots an assault rifle out the back of an Audi S8. The shooting results in big explosions. It's worth a look yourself, to get in the mood for the next episode which hits Amazon on Friday. Related Video:

Castrol Nexcel is an oil change in a box

Oil changes are a vital part of car ownership. For some this simple bit of maintenance gives them a sense of accomplishment and a closer connection to their car. Others just find it a hassle. Castrol might have a compromise with new tech called the Nexcel that packages the oil and filter into a single, easily removable container. The company claims switching the unit out takes just 90 seconds. Instead of draining the oil for a regular change, the whole Nexcel is replaced each time. Castrol then retrieves the used containers and recycles the fluids inside into other lubricants. The exclusive cadre of ultra-wealthy buyers for the track-only Aston Martin Vulcan get to be the first ones to find out if the Nexcel lives up to the hype. And don't worry, the container can reportedly stand up to the hypercar's punishment. According to Castrol, the Nexcel has been tested to perform at up to 1.8G and can flow as much as 158.5 gallons of oil a minute. The tech also allows Castrol to create specific oil blends to match to different engines. "Today, you can't guarantee the right oil will be used, so the degree to which oils can be tailored is limited. Nexcel is different and can go further. The oil cell enables a concept we call precision lubrication," a spokesperson said to Autoblog. Assuming the Nexcel is a success, Castrol estimates that it could arrive in the first road car in about five years. The company already claims to be in discussions with "several" automakers about potentially implementing the tech. While changes would be far quicker, some enthusiasts might balk at the idea of being locked into oil from just a single brand, though. CASTROL REINVENTS OIL CHANGE WITH NEXCEL: THE REVOLUTIONARY TECHNOLOGY THAT MAKES OIL CHANGES QUICK, SMART AND SIMPLE The Nexcel oil cell, an easy-to-change unit containing both engine oil and filter delivers superior engine performance and improved environmental sustainability The new technology allows your oil to be changed in around 90 seconds, more than 13 times faster than a conventional oil change of 20 minutes The Aston Martin Vulcan track-only supercar will be the first vehicle featuring Nexcel technology LONDON, Thursday 8th October 2015 – Today, Castrol launches Nexcel, a new revolutionary technology that marks the most significant oil change innovation in automotive history.
