Here is a video that explains what exactly vortex generators are, and even how specifically they improve a car’s aerodynamics.

The Pikes Peak International Hillclimb may be known for the number of highly modified race machines vying to be the fastest up the iconic mountain, but few can say they have done it behind the wheel of a semi-truck.

Enter Banks Power Systems, an aftermarket performance shop specializing in diesel engines. In what may be one of the best ways to show off just how capable its aftermarket parts are, the company built a 1000-plus-horsepower turbo- and supercharged semi-truck to conquer Pikes Peak.

Rust—or “nature’s weight reduction,” some readers call it—is a problem for any vehicle, no matter what kind or how old it is.

To ensure that a car has a fighting chance against the elements, manufacturers send their cars through a series of punishing tests to evaluate what does and does not survive.

Under high-horsepower loads, the serpentine belt of your engine can stretch, leaving an increased risk of it slipping off.

To combat this, cars like this supercharged COPO Camaro have a specialized belt tensioner to keep the belt completely taut during runs down the quarter-mile.

Honda put together this video–it remind us of Gran Turismo–as part of the NSX’s 30th birthday celebration. It highlights the various versions of the iconic that have been built since its debut.

Video: Watch the RUF CTR Yellowbird Tackle the Nürburgring
Posted by Colin Wood on Oct. 12, 2020, 8:35 a.m. https://www.youtube.com/embed/OSMCfPASImQ

To say that the RUF CTR Yellowbird was a handful may be an understatement, as its 911 engine was enlarged to 3.4 liters while receiving a pair of turbochargers. Yellowbird was good for more than 460 horsepower and 400 lb.-ft. of torque—in a car that weighed a little over 2500 pounds. At the time, it was simply nuts. 

This is what it’s like to wrangle all that around the Nürburgring.

Video: Just How Much Abuse Does the Nürburgring Put on Brakes and Suspension? See for Yourself
Posted by Colin Wood on Oct. 8, 2020, 10:10 a.m. https://www.youtube.com/embed/bBAy8AmGFTM

The Nürburgring is one of the most challenging and punishing race tracks on the planet. What better place, then, to observe the massive amounts of abuse that the track puts on brakes and suspension components.

Of course, track-focused parts like the ones on this BMW M3 are built to take that abuse, but that doesn't mean it's an easy job.
