2007 Lotus Elise on 2040-cars

This 450-hp electric Lotus Evora is powered by Tesla and Chevrolet

When someone mentions an electric Lotus, the first thing that comes to mind is the Tesla Roadster, the California-based automaker's first vehicle. That car started life as an Elise before being heavily massaged and adapted by Tesla's engineers. In a similar spirit, the people at Onpoint Dyno are close to finishing Blue Lightning, a track-ready all-electric Lotus Evora. Blue Lightning uses a Tesla drive unit and a Chevrolet Volt battery pack, both mounted in the middle in place of the Evora's 3.5-liter Toyota V6. It's putting down about 450 horsepower at the wheels. The car was built for time attack sessions, so power is fed through custom forged wheels and super sticky Pirelli PZero Trofeo R tires, the same ones found on the last Chevrolet Camaro Z/28. There is a custom digital instrument cluster in place of the Lotus gauges. There's also a regen paddle on the left side of the steering wheel. With a full charge, Blue Lighting should go about 120 miles. While the car runs under its own power, it's only about 90 percent complete. It has no power steering, no firewall in between the seats and the motor and battery pack, no A/C, and a large hole where the shift lever used to be. Other final touches include fine-tuning the brakes and suspension. There is also a custom rear bumper coming that should make it look more like the new Lotus Evora 400. Onpoint Dyno expects the car to hit the track in the next month or so. Related Video:

The black and gold Lotus Evora Sport 410 GP Edition is heading to America

Few race teams have such deeply iconic liveries as Team Lotus. From the Gold Leaf cars from the late 1960s to the bright yellow Camel cars that lasted until the early 1990s, arguably none is more iconic than the John Player Special cars that brought world championships to Emerson Fittipaldi and Mario Andretti. Now that same sleek black and gold paint scheme can be had on the new Lotus Evora Sport 410 GP Edition. Even better, it's heading to America. While the GP Edition isn't anything more than a special paint scheme, what a wonderful design it is. The livery is based on the John Player Special Team Lotus cars that competed in Formula One between 1972 and 1986. The black paint is accented with gold stripes along the hood, fenders, doors, and rocker panel. Gold Evora Sport 410 logos adorn the rear while a "Word Champions" emblem flanks the engine cover. The Evora Sport 410 is the lighter, faster version of the thoroughly reworked Evora 400 that we drove last year. Lotus says it's the fastest road car the automaker has ever built. It hits 60 miles per hour in 3.9 seconds and tops out at 190 mph. They US version has been specially curated by Lotus engineers in order to be both light and meet federal crash test standards. Unfortunately, Lotus is only building 150 total each year for worldwide markets. Related Video:

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.
