  • Engineering Explained examines a catback exhaust system

    Finding the aftermarket modifications that will make your car a better performer can be an adventure. Every company under the sun claims all sorts of horsepower, torque, and efficiency gains, but do those claims actually prove out in the real world? Not always. However, some mods will help improve the performance of your car. One of those is a catback exhaust system, which opens up exhaust flow and can save weight. Jason Fenske from Engineering Explained acquired a catback exhaust system for his project Honda S2000. Since he's all about the science of everything, Fenske set out to determine...

  • Volkswagen's new Budack engine cycle
    How does VW's Budack engine cycle work?

    Volkswagen isn't reinventing the way your internal combustion engine works. The automaker has, however, created a new twist on the Otto cycle that's a revised version of the Atkinson cycle.

  • Jay Leno drives a 1974 Porsche 914-6 GT
    1974 Porsche 914-6 GT tribute car visits Jay Leno's Garage

    At the end of the 1960s, Porsche was on the hunt for a model that could slot into the family lineup below the 911. Working with Volkswagen to make this happen, Porsche came up with the 914, and it proved to be quite popular. In fact, the relative affordability of the 4-cylinder-powered 914/4 helped...

  • Here are 5 ways electric cars out perform gas-powered cars
    5 ways electric cars outperform gas-powered cars

    A proper gas-powered car is a joy to drive. Your senses take a joy ride when the sound hits your ears, the acceleration tosses you in your seat, and sometimes even the smell wafts into your nose. The days of gas-powered cars are numbered though. This is a fact we can't deny. Electric cars, however...

  • BMW E30 M3
    Everything you need to know about the BMW M3

    When enthusiasts think German sports car, they often think BMW M3, and there's a good reason for that. The M3 came to life as a race car first, and a street car second. Donut Media's latest "Up to Speed" episode focuses on the M3 and traces the iconic sports car's history back to its DTM racing...

  • Jon Olsson's custom Mercedes-Benz G500

    Jon Olsson isn't just a professional freeskier and ski racer, he's also a horsepower junkie. Why do we say that? Because he owns multiple wild creations that make in excess of 800 horsepower, including one of the most rambunctious Rolls-Royce Wraiths we've ever seen. Now, there's this: his new 800-hp Mercedes-Benz G500 4x4. Absolute Motors, a performance shop in The Netherlands, once again helped Olsson bring his latest creation to life, though the SUV will return for official dyno numbers in the near future. The 800 hp figure is only an estimate at this time. We don't have a full spec sheet...

    Ken Okuyama Kode 0 visits Jay Leno’s Garage

    It’s great to see the practice of coachbuilding, where a custom body is draped across a donor chassis, is alive and well. That’s thanks in part to talented designers like Ken Okuyama. The man is most widely recognized for his work done at Pininfarina, where he penned such masterpieces...

  • Watch this Porsche 911 GT2 RS blow past 200 miles per hour
    Watch the 2018 Porsche 911 GT2 RS blow past 200 mph

    The magic number you're looking for here is 321. That's the figure, in kilometers per hour, that translates to the magic barrier that is 200 mph. This is the number that separates truly fast cars from ones that merely knock on the door of fast. Porsche gets this, and that's why the 2018 911 GT2 RS...

  • This is how you trail brake in a car
    Performance driving technique: how to trail brake

    You're coming hot. The corner is looming large out the front glass and you need to get this vehicle slowed down quickly. If you stomp on that brake pedal, you're likely to lock up the wheels and blow right through the corner. If you don't use enough brakes, you're also going through the corner...

  • Ferrari LaFerrari Aperta
    The wheel weight placement on a Ferrari LaFerrari will surprise you

    I had to hurry to see if for myself. There was a LaFerrari at my local Cars and Coffee over the weekend, but I wasn't in a rush to see this particular car. Instead, I wanted a closer look at the wheels. A friend had tipped me off that they were worth a glance specifically because something seemed...

  • Why the Honda Civic Type R doesn't have torque steer

    The Honda Civic Type R is an impressive little beastie. In fact, if you missed it, we named Honda's hot hatch the Motor Authority Best Car To Buy 2018. We lauded its handling capabilities, and a major part of the magic is how Honda managed to basically eliminate torque steer in a 306-horsepower front-wheel-drive car. Why doesn't it exhibit torque steer or at least much torque steer? Thankfully, Jason Fenske of Engineering Explained is here to, well...explain it. First a definition. Torque steer occurs when engine torque actually affects a vehicle's steering. It's prevalent in high-power...

  • 2017 Hennessey VelociRaptor 6x6
    Why would anybody want a Hennessey F-150 VelociRaptor 6x6?

    Pickup trucks are uniquely American vehicles. They were first envisioned to not only transport people but also to haul whatever their owners needed in a bed.

  • 1991 BMW M5
    BMW explains what to look for when buying an E34 5-Series

    The BMW 5-Series has long been a beloved uber sedan. In its most basic form, it represents a powerful and moderately upscale entry in the mid-size luxury sedan segment. At the upper end of the scale you have the mighty M5, which remains the measuring stick by which other sports sedans are measured...

  • 1967 Chevrolet Camaro
    The Chevrolet Camaro was a direct response to the Ford Mustang

    The world is full of emulators, and the automotive industry isn't short on them. In fact, the Chevrolet Camaro might be the greatest of all time.

  • 2018 Rolls-Royce Phantom
    The science behind Rolls-Royce's oddball four-rotor diesel rotary engine

    This is the strangest engine you've likely never heard about. Back in the late 1960s and early '70s, a number of automakers were experimenting with odd engine setups. Heck, that happens all the time, even today. This particular setup was quite odd, however, in that it was a diesel rotary. Making it...

  • The Devel quad-turbo V-16 makes over 5,000 horsepower
    Watch Devel’s 12.3-liter quad-turbo V-16 make 5,007 horsepower

    When a new hypercar builder arrives on the scene, it's met with lots of skepticism and eye rolling. It's typically all warranted, though, as these cars promise insane speeds, crazier price tags, and an often imaginary waiting list. This is also usually accompanied by press release photos that are...

  • Subaru Impreza WRX rally car

    Before the Subaru WRX landed in the United States, there wasn't much of a market for affordable and practical performance cars. Think about it for two seconds. Before the WRX, name something similar. Sure, performance coupes were big, but not sedans with proper sports car credentials. It's safe to say Subaru changed the U.S. automotive landscape with the WRX's introduction. And now, you can learn all about it thanks to Donut Media. Born from rally racing, the Subaru WRX, called the Impreza WRX for years, came to life on the rally stage in 1993. Subaru first ran the larger Legacy in rally...

Alongside the birdcages, Pierce added bicycles and in 1901 cars were introduced to the...

  • This is an Audi S1 on tracks
    This is an Audi S1 on tracks and it looks like fantastic fun

    When Audi decided to take its diminutive A1, it probably figured that an S variant would soon follow. The automaker probably never considered, however, that someone would buy an S1 and stuff a set of tracks in the wheel wells. Someone did, and all we can say is that we want to give it a go...

    E30 M3 does hill climb with screaming 440-HP E46 M3 engine

    You'll often find builders of hot rods and muscle cars talking about upping the displacement on a given engine. Taking a Ford 390 and turning into a 428, for example.

    Larry Kosilla is our favorite type of automotive mad man. Without his obsession to detail, he wouldn't be a detail king and the person bringing Ammo NYC cleaning products to the world.
