Jay Leno sees how the other half lives with CHP cop cars new and old

Comedian Jay Leno is changing gears from driving fast cars to checking out some of the police cruisers that regularly chase down and dish out punishment to those fast cars. In this episode of Jay Leno's Garage, we get the lowdown on the modifications made to the Ford Explorer for the Interceptor package (which looks pretty tough in its California Highway Patrol livery).
The new Ford is cool, but cooler still are the pack of classic CHP cars that Jay has along for the episode. A 1982 Mustang, 1966 Dodge Polara, 1970 Mercury Monterey and 2000 Crown Victoria are all in the shop. Better still, Jay lays out an argument for ones of the classic cruisers as the best cop car of all time. Get your guesses in now, and then scroll down to watch and learn.

Experts wonder if aluminum F-150 gives Ford a real advantage

There's no doubt that Ford is taking a risk in producing the body of its upcoming new F-150 pickup truck in aluminum. What is up for debate, however, is whether aluminum was a wise risk to take in the first place. Wards Auto took the opportunity to poll some experts on the subject of aluminum versus steel in the automotive sector, with somewhat unsurprising results.
Richard Schultz, a project consultant at Ducker Worldwide, which bills itself as "a leading aluminum industry consultant (though they also deal in steels), suggests that the potential drawbacks to aluminum - higher costs, lower supply - aren't really impediments to the auto industry's increased acceptance of the lightweight metal.
Similarly, Randall Scheps, global automotive marketing director for Alcoa, a massive aluminum producer, counters claims that aluminum is less safe for vehicle occupants, suggesting that the use of aluminum can actually increase safety as it could potentially allow for larger vehicles with more crush space than steel.

Chevy Silverado frame twist test a marketing victory versus Ford

The pickup market is so competitive that all three major American makers are constantly trying to find a way to prove their product is the best. The new 2015 Ford F-150 is grabbing headlines at the moment by winning awards and posting segment best numbers. But in a new video, Chevrolet is taking aim squarely at the 2015 F-250 Super Duty in a battle of heavy-duty truck supremacy against the 2015 Chevy Silverado 2500HD... well, in a single metric anyway.
The big numbers from pickups often come down to payload, towing rating and fuel economy, but for this test, Chevy and Howie Long are challenging the torsional rigidity of the trucks' frames, specifically which one flexes less. Long plays the everyman here having the Chevy engineer explain what's going on in the tests. Unsurprisingly for a video on Chevy's official YouTube page, the 2500HD wins out by a good margin. The company also reports that similar results as shown here have been certified in third-party testing.
Check out the video to see the full test. While this might seem like a marketing win for Chevy, Ford isn't immune to it, either. In 2009, the Blue Oval uploaded a similar video comparing the flex under 225 pounds of weight from the bare frames of the F-150, Chevy Silverado, Dodge Ram (as it was still called at the time) and the Toyota Tundra. The results fell in the Blue Oval's favor, as you can see here.
