Watch the Lotus Esprit evolve from 1976 to 2004

Seeing a model as long-lived as the Lotus Esprit evolve over time generally requires some clever photography or graphical work, kind of like this. This video doesn't require any of that trickery, though, because it features every single model year of Espirt in one glorious row of awesome British cars.
Taken at the 2013 Lotus Festival at Brands Hatch in the UK, it features Esprits from 1976 all the way to its last model year in 2004. It really puts into perspective the slow evolution of the mid-engined, wedge-shaped Lotus, as it went from a very 1970s design to something decidedly more modern.
We've got the full video below, which starts with a red 1976 model, travels down the line to a silver 2004 Esprit, and then all the way back to the original. Take a look, and let us know what you think.

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.

Radford Type 62-2 is rad, a coachbuilt sports car based on Lotus underpinnings

There’s a new coachbuilder out there, and the company calls itself Radford. Today, Radford revealed its first car — the Type 62-2 — and itÂ’s based on the chassis and underpinnings of the Lotus Evora. ThatÂ’s an extremely good place to begin building from. Plus, the company has some big names attached to it. F1 racer Jenson Button is the one who dialed in the carÂ’s driving dynamics. Mark Stubbs, formerly of Bentley, Bugatti, Aston Martin and more, led the design process. And Ant Anstead, now co-hosting "Wheeler Dealers," is handling the build/production work. There may be an Evora underneath all the new bodywork, but this vehicle doesnÂ’t look like one on the outside. Instead, itÂ’s meant to take after the original Lotus Type 62 race car. Take one quick look at both, and it appears as though Radford has done a standup job of getting it there. ItÂ’s even been revealed initially in livery worn by the old Type 62. WeÂ’ll note that there will be two cars with slightly different looks. The first is a “Classic” version without a wing and fitted with staggered 17/18-inch wheels. The other model is called “Gold Leaf,” and it has the Type 62Â’s wings, can be done in the livery you see here and features larger center-locking 18/19-inch wheels. Thanks to the aluminum-intensive structure of the Evora, the Radford Type 62-2 weighs just under 2,205 pounds. Radford saved additional weight by using all carbon fiber body panels. This lightweight body is propelled forward via the 3.5-liter Toyota-provided supercharged V6 used in the Evora. Its base tune in the Type 62-2 offers up 430 horsepower. However, upgrading from the Classic to the Gold Leaf brings an increase to 500 horsepower. Radford says it gets the extra power via upgraded pistons, connecting rods, camshafts and new electronic engine mapping. If you want the extra power in the Classic, Radford says you can still optionally have it. As you may already suspect, a six-speed manual transmission is available on the Type 62-2. Unlike the Evora, though, you can also spec a seven-speed dual-clutch automatic transmission. ItÂ’s the only transmission available if you spec the engine up to 500 horsepower, so pick your poison on that front — thereÂ’s no manual available for the high-power version. As for the suspension, Radford says itÂ’s lowered the car more and changed the suspension geometry a bit compared to the standard Lotus design — thanks, Jenson.
