  • Volvo Drive Me autonomous car pilot project in Gothenburg, Sweden

    Volvo in 2014 announced an ambitious project that would see autonomous car prototypes handed to members of the public for evaluation. As part of the project, called Drive Me, 100 of the prototypes, all of them based on the XC90 SUV, would be lent out to participating customers in Gothenburg, Sweden starting in 2017. Volvo on Friday announced it had started building the 100 XC90 prototypes. The prototypes will now undergo a rigorous testing phase to ensure their self-driving technology functions exactly as required. Once this testing phase is finalized the vehicles will be handed over to the...

    Can you improve acceleration by adding weight?

    Before you start shaking your head and shouting "No!" at your computer screen and preparing an angry email about how stupid we are, hear us out. Our host Jason Fenske from Engineering Explained is referring to the addition of weight when traction is limited, such as in snowy or icy conditions. In...

    How variable intake manifolds create more power

    Your intake manifold. It takes in air and sends it to your engine's combustion chamber. This is basically the start of the combustion process. After all, you can't have combustion without air. Engineering Explained is here to walk us through the process and explain how a variable intake manifold...

  • Kia's new 8-speed automatic transmission

    Kia has taken the increasingly unusual step of developing its own automatic transmission, a new 8-speed that debuts in the automaker's Cadenza sedan set to arrive in dealers within the next couple of weeks. In the Cadenza, the 8-speed mates to a 3.3-liter V-6—but it's safe to assume that the Korean automaker will extend its high-tech gearbox to other engines moving forward. The 8-speed isn't Kia's first attempt at more than a half dozen gears; the company's rear-wheel drive K900 flagship utilizes an 8-speed automatic that was developed by Hyundai. But unlike the K900, the Cadenza (not...

    The 2017 Jeep Wrangler just received modern headlights

    A new Jeep Wrangler is on the way, but that doesn't mean the current model isn't getting enhanced for 2017.

  • How Infiniti's variable compression engine works

    You know what variable valve timing is. You're quite familiar with Honda's VTEC system. Now Infiniti has something new for you dive into, and it's all about changing an engine's compression ratio. The Infiniti VC-T engine can change its compression ratio from a low of 8:1 to a high of 14:1. How does it work? Engineering Explained is here to clue us all in. Using a turbocharger and the variable compression ratio, the engine in question can alternate between power and fuel economy needs. Most engines are better in one area while losing out a bit in another. In this case, though, there's none of...

    Why the Ford GT uses hydraulic-assist power steering

    Every new vehicle these days seems to have electric-assist power steering. This type of system saves weight, space, and a bit of fuel. It's not, however, always the most enjoyable setup from an enthusiast standpoint. EPS systems often lack steering feel. We're happy to report, then, that the new...

    What's the difference between steel and rubber brake lines?

    Your car's brakes are pretty darn important. If you have lousy pedal feel, you should do something about that, right? Stopping is at least as important as going. So when you're looking to fix or upgrade your brake system, should you go with rubber lines or jump up to steel brake lines? Engineering...

Luckily, our pal Jason Fenske with Engineering Explained is...

  • Tesla Autopilot suite of features  -  with version 7.0 update

    Buried somewhere between longer range and furious acceleration (and resulting "meh" by the collective automotive journalism brain trust), Tesla on Tuesday nudged up the price of its Autopilot feature. The fine folks over at Electrek were paying attention and noticed that Tesla's online configurator now notes that Autopilot is a $3,000 extra from the factory, or $3,500 if enabled later. That's an increase of $500 (or 20 percent for math majors) over the price Monday, which started at $2,500 and $3,000 respectively. Tesla confirmed to Motor Authority that it hasn't changed the Autopilot...

    How Porsche gave the world more turbos, faster

    Buried deep within the 2017 Porsche 911 Turbo is an engineering "no-duh." Talk to anyone with a cursory knowledge of the widowmaker from Stuttgart and they'll say the old Turbo 911s required three feet in any given corner: one for the brake, one for the clutch, another to feed the throttle so...
