Lotus introduces Certificate of Provenance program

Lotus is diving into its vast archives to make it easier for owners to trace their car's history. It launched a global program called Certificate of Provenance that provides historical information about a specific car. Available through authorized Lotus dealers, the Certificate of Provenance includes details like the car's VIN and its original color. It also notes the date the car rolled off the assembly line in Hethel, England, and the date it entered the company's dealer network. Key specifications, including the engine, the transmission, and the extra-cost options the original owner ordered, are printed on a personalized Build Specification Letter. Owners who order the certificate will also receive a letter from Lotus CEO Phil Popham in which he pledged to explain the changes going on at the company, and how it's preparing for the future. Summing up the situation in a letter will likely be easier said than done, because Lotus (which is now controlled by Geely) is undergoing a complete transformation that includes a major product expansion and a renewed focus on the American market. It called the Evija, its first electric model, a trailblazer whose technology will permeate other battery-powered cars.   Related: Geely, with Volvo's help, plans to grow into a global auto giant   In addition to the aforementioned documents, enthusiasts who order a Certificate of Provenance will also receive an aluminum plaque engraved with the owner's name, a leather keychain, a carbon fiber bookmark, and a Lotus pen. Pricing starts at GBP170 plus the cost of shipping in the United Kingdom, a sum that represents about $225. And any Lotus owner can order it regardless of whether they own a 1959 Elite or a 2020 Evora GT. The first car certified by Lotus is a 1981 Esprit Turbo (pictured) that stands out as the last company car ordered by company founder Colin Chapman. Wearing registration number UVF 464X, it remained in Chapman's possession until his death in 1982, and it was sold to a private buyer the following year. Lotus recently purchased it with 11,000 miles on its odometer, and it plans to restore it before adding it to its heritage collection. Chapman didn't settle for a regular-production Esprit Turbo. He ordered his car with power steering (which wasn't available on the Esprit at the time), a lowered suspension, and modified brakes. He also ordered BBS wheels. Related Video:

Lotus won't launch a 3-Eleven successor until it overhauls its range

Lotus has received an enthusiastic response to limited-edition models like the 3-Eleven. It's open to the idea of making similar cars, but Autoblog learned fans shouldn't expect to see one until it has overhauled its range. "There is room for it, but we have so many things to do that we're already committed to. Getting a new product range out there is the priority," Matt Windle, the firm's engineering boss, told us during an interview. The decision to wait is a wise one, because Lotus has a lot on its plate for a small company. It's putting the final touches on the electric, 2,000-horsepower Evija, it's allegedly working on a new Esprit with hybrid power, and unverified rumors sketch the outline of an SUV pegged in the same segment as the Porsche Macan. On the other hand, the global market's appetite for few-off models is healthy. Bentley had no trouble selling 12 examples of the Bacalar, for example, and even Aston Martin wants a piece of the pie. This trend isn't lost on Lotus; it knows it's in a unique position to capitalize on it. It competes at a lower price point than most other companies making limited-edition cars, and its "light is right" motto is still revered in enthusiast circles. While its car-building division is busier than ever, its engineering arm has the bandwidth to work on special projects. "Lotus Engineering, the consultancy side of the business, is going strong as well. We've been talking about bespoke programs with other companies. That's one way we could deal with that, and it would take it away from the main product development teams. Nothing is confirmed yet, but there are a lot of discussions going on," Windle revealed without giving too much away. Lotus has been there before. It notably helped John Z. DeLorean bring the DMC-12 to the market, and it transformed the Opel Omega into the fastest sedan in the world. Some of our geekier readers will remember the "handling by Lotus" emblems on the Isuzu Impulse. It has worked on several General Motors engines, too, including the EcoTec unit that once powered several Saab, Saturn, Chevrolet, and Pontiac models. The next limited-edition Lotus will have big shoes to fill whenever it arrives. The aforementioned 3-Eleven stood proud as the fastest street-legal Lotus when it made its debut in 2015, and the 430 variant (pictured) launched in 2018 put an even greater focus on performance.

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.
