This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.

Lotus-based Radford Type 62-2 shows its retro-styled interior

England-based Radford introduced the Type 62-2, a limited-edition coupe with a heritage-laced design, earlier in 2021. But it didn't show us the interior. Now, Radford finally revealed what the car looks like inside, and it's a blend of retro styling cues and modern tech that enthusiasts will love. At first glance, the Type 62-2's cockpit looks like it's from a different era. The driver faces a meaty three-spoke steering wheel, the shift linkage is exposed, and there is a pair of Bremont instruments (one is a clock, the other is a stopwatch) positioned on the passenger-side of the dashboard. We could be describing a 1970s rally car. However, a closer inspection reveals features buyers expect from a car in 2021. Look behind the steering wheel (whose spokes are made with carbon fiber) and you'll spot a digital instrument cluster with a layout that can be configured by each buyer. You could, in theory, ask for the tachometer to be front and center, for example. Screens positioned on either side of the dashboard display the footage from the cameras that replace the exterior mirrors, and a phone dock that doubles as a wireless charger is hidden behind the build plate located on the center stack. Users can set their phone there to access navigation and music apps.  Radford Type 62-2 John Player Special View 5 Photos Buyers will have three basic trim levels to choose from: Classic, Gold Leaf, and John Player Special. Each one will receive a specific look inspired by liveries that Lotus race cars have used in the past, though buyers will be invited to configure their car exactly how they want it. What won't change is the engine: it's a supercharged, 3.5-liter V6 that found its way into the Type 62-2 from Toyota via the Lotus Emira. Bolted to either a six-speed manual transmission or a seven-speed dual-clutch automatic, it develops about 430 horsepower in the Classic model, around 500 in the Gold Leaf, and approximately 600 in the John Player Special thanks in part to a specific supercharger. Radford will build 62 units of the Type 62-2, and production is scheduled to start before the end of 2021. Deliveries will begin in early 2022. Pricing information hasn't been announced, but don't expect this rare British coupe built largely by hand to come with a bargain price.

Lotus C-01 motorcycle shows its carbon-fiber face

Well, this isn't exactly what we were expecting. The images you see above come from Motorcycle News in the UK and are apparently official renderings of what the upcoming Lotus C-01 motorcycle will look like. As you can see, it's sort of a power cruiser, with a raked-out front end and extremely wide rubber out back.
Power will reportedly come from a liquid-cooled V-twin engine sourced from KTM, similar to the one used in the Austrian's brand's own RC8R, but tuned to produce around 200 horsepower. It appears that the powertrain and all its related necessities will be housed in a carbon fiber monocoque (whether the bodywork serves as a stressed member or not, we can't say) in a traditional-looking black (really, exposed carbon fiber weave) and yellow color scheme.
From the looks of these renderings, the C-01 might be intended as a competitor for the Ducati Diavel and ought to be very quick in a straight line. We're not so sure that's what a motorcycle wearing the Lotus badge should be, even if its builders are only using the marque's name under license, but we're looking forward to seeing the final result in production trim.
