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.

2020 Lotus Evora GT First Drive | Exquisitely analog

OJAI, Calif. — WeÂ’ve glimpsed LotusÂ’s EV-powered, 2,000-horsepower, $2 million future, and itÂ’s a glorious vision, for sure. But the boutique brand has also updated its more attainable gas-powered offerings back here on Earth, in the form of the 2020 Lotus Evora GT. Our first drive offered a revealing (and thrilling) taste of what might be among HethelÂ’s last traditionally-powered sports cars. For those unfamiliar with the Evora, the diminutive 2+2 was launched in 2009 as a grand touring-capable alternative to the laser-focused, ultra-featherweight Elise. Power hails from a Toyota-sourced 3.5-liter V6 with Lotus-modified induction and exhaust hardware, with everything from the throttle calibration to the spark plugs tweaked, and oil sump baffles added to reduce sloshing during high g-force maneuvers. While supercharger oomph was added to the Evora 400Â’s powerplant in 2015 (breaking the, you guessed it, 400 horsepower barrier), the latest GT spinoff incorporates mods from the non-U.S.-spec Evora 430, which brings total output to 416 hp and 317 lb-ft of torque. As before, a six-speed manual comes standard (and accounts for approximately 70% of sales), while an automatic adds $2,700 to the $96,950 starting price. Thanks to an infusion of carbon fiber and composite bits, the Evora GT tips the scales at only 3,175 pounds – for context, thatÂ’s only 33 lbs more than a Porsche 911T – aided by a bonded aluminum tub that manages both light weight and excellent torsional rigidity. Opt for the carbon pack ($10,000), and youÂ’ll shave an additional 71 pounds from the equation. Further mass reduction is available via forged wheels ($3,250) and titanium exhaust ($8,000). Revised aerodynamics in the form of tucked-in wheel arch vents, a slight drop in ride height, and a larger rear spoiler conspire to double downforce, producing 160 lbs of force at the 188-mph top speed. If youÂ’ve ever endured the awkward ingress and egress of a Lotus Elise, the Evora feels refreshingly conventional: simply slide in, click in, and adjust your mirrors diligently because, at least if youÂ’ve ordered the carbon package, visibility through the rear windows is almost entirely obscured by thick louvers. Like that other British performance brand (looking at you, McLaren), Lotus stuck to its guns by retaining a hydraulic steering rack that conveys road surface nuances and feedback with refreshing accuracy.

Lotus Type 132 electric SUV previewed ahead of March 29 debut

Lotus is about to unveil its most important and most controversial car. It will jump into the electric crossover segment when it launches a model called Type 132 internally, and it released a short video that gives us a preview of what the people-hauler looks like inside and out. Aimed at the Porsche Cayenne, among other high-riding and high-horsepower machines, the Type 132 will spearhead the British firm's entry into the mainstream; it likely won't be a high-volume model but we're betting it will become the best-selling Lotus. The preview video reveals a handful of styling cues, like a light bar that stretches across the rear end, and it confirms that the cabin will offer a long list of tech features. Drivers will face a digital instrument cluster and a meaty steering wheel with backlit buttons and a pair of shift paddles, though it's too early to tell what purpose they'll serve. We know that the Type 132 — a name which won't be retained for production — will be entirely electric so the paddles will very likely not be connected to a gearbox. Both are labeled "+" and they may be used to adjust the level of regenerative braking. If that's the case, then odds are there's also a "-" symbol on each paddle that's hidden from view in the 1:12-long teaser video (shown above). Lotus Type 132 preview View 4 Photos Spy shots taken in China in February 2022 suggest that the Type 132 will tilt more towards the sporty side of the crossover scale; Lotus isn't interested in rivaling, say, the Mercedes-Benz GLS in terms of passenger and cargo space. The sheet metal will hide a modular platform called Evolution Architecture, and the crossover will reach 60 mph from a stop in under three seconds in its most powerful configuration thanks in part to a dual-motor powertrain. It will be interesting to find out how Lotus, whose founder's now-famous motto was "simplify, then add lightness," will offset the lithium-ion battery pack's significant weight. Lightweight materials, like carbon fiber, will certainly play a role. Lotus will introduce the Type 132 online on March 29, and production will start shortly after in a new facility located in Wuhan, China. Looking ahead, the company plans to continue its model offensive by releasing a four-door sedan that's called Type 133 and tentatively due out in 2023, a second SUV known as Type 134 that we should see in 2025, and a sports car dubbed Type 135 that will make its debut in 2026.
