National Geographic Channel balances Ford F-150 on four coffee mugs

Proving that there is still something to be learned on television these days, National Geographic Channel recently introduced a new series called Duck Quacks Don't Echo. On the first episode of this science/comedy show, host Michael Ian Black proposes the idea that a truck can be supported with a ceramic coffee mug under each wheel - yes, he says that the entire weight of a truck can be balanced on just four coffee mugs.
Looking to find out whether this is fact or myth, the show uses a regular cab Ford F-150, weighing in at 4,800 pounds, and four average coffee mugs. Lowered onto the mugs, the idea is quickly put to the test. Can the cups hold up under 4,800 pounds? If so, what, exactly, would it take to break them? Scroll down below to find out.

Weekly Recap: 2016 CTS-V gives Cadillac new momentum for the new year

It's been a rough year for Cadillac. The historic luxury carmaker been in the news for all of the wrong reasons: Declining sales, ditching its advertising agency and the relocation of its headquarters from Detroit to New York. But in late December, Cadillac reminded everyone what it does best: Build some of the rawest and most compelling luxury sedans in the world, as evidenced by the 2016 CTS-V. This monster churns out 640 horsepower from a supercharged 6.2-liter V8. Sound familiar? That's the Corvette Z06 engine, and it makes this CTS the most powerful production Cadillac ever. It also puts the sporting divisions of the Germans on notice. The new CTS-V easily overpowers the Mercedes-Benz E63 AMG S 4Matic and its 5.5-liter biturbo V8 rated at 577 hp, and the BMW M5 (with the competition pack) and its 4.4-liter twin-turbo V8 that pushes out 575 hp. The rear-wheel drive Cadillac can sprint to 60 miles per hour in 3.7 seconds, which is close to the 3.5-second time turned in by the 4Matic-driven E63 S, and a bit quicker than the 4.1 seconds posted by the M5. With Magnetic Ride Control, General Motors' stout eight-speed automatic transmission (also used in the Corvette), Brembo brakes and a carbon-fiber option package that pretty much builds your car out of carbon fiber – it's clear this Cadillac means business. Truth be told, we expected this CTS-V to deliver. It's been a serious sports sedan for a decade, and the recent generation and its 556-hp arrogance have been particularly memorable. But notice what we're doing here? We're talking about product. Not who makes Cadillac's ads, or if the brand's headquarters has a mailing address in NYC. Like the 2016 ATS-V that's due in the spring, the debut of the 2016 CTS-V (on sale in late summer) is a shot in the arm for Cadillac, and its arrival comes during time of transition. The brand is trying to reinvent itself as a modern luxury maker. It wants new customers, a different image and obviously more sales. Those things are going to take time, but with a 640-hp sledgehammer of a sports sedan on tap for next year, Cadillac can still maintain some of its swagger through all of the change.

Radical RXC is a Mustang-hearted racecar for the road

Radical has been building fantastic open-cockpit racers and roadcars for years, for the track day enthusiast who wants a vehicle that looks like it could show up for a start at the 24 Hours of Le Mans. The company's latest creation is the RXC, and while this coupe looks like a prototype racer, it's road legal in the UK and in some parts of the US. When testing a car this, um, radical, the first thought is likely to get it to the track for some big slides and wide open acceleration, but XCar Films takes the opposite approach in its latest video to learn how this racer fares on public roads. The version tested here is the standard RXC with the 3.7-liter V6 out of the Ford Mustang tuned to 350 horsepower with a seven-speed sequential gearbox; but Radical also offers the same engine with 380-hp, a 454-hp Ford EcoBoost 3.5-liter twin-turbo V6, or even a 500-hp V8. Even in the most basic guise, it's a handful to control in the wet, if this video is any indication. The cliche of a road-legal racecar is bandied around a lot in the motoring world, but it truly applies to the RXC. The only problem with seeing the RXC exclusively on the road is that it can never really open up and show its full potential. This racer is indeed chomping at the bit to rocket off into the horizon, but all those pesky road safety laws hold it back. Still, the video is a chance to get a better impression about this thoroughbred sports car. Scroll down to check it out. This content is hosted by a third party.
