1997 Lotus Esprit V8 on 2040-cars

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 Eletre opens a new front in electric SUVs

Ladies and gentlemen, the new era of Lotus as an EV maker begins with this, the Eletre. It takes elements we've seen on the Evija battery-electric hypercar and Emira ICE sports car, wraps them in a larger package, jacks them up, and throws in a lot of new tech for the brand and the market. Let's start with size, which is the easy bit. The Eletre is 201 inches long on a 118.9-inch wheelbase, about 79 inches wide, and 64 inches high. Every one of those dimensions puts the Lotus within a couple of inches of the Aston Martin DBX: the EV being a little longer, with a slightly shorter wheelbase, a little wider, and a roof a couple of inches lower. For us, the side view most closely represents the form we had in mind based on recent spy shots. The front is intense, the yellow of the hero car making the greatest contrast with the polygonal void below. The lights above the leading edge are DRLs and turn signals, the main beams are recessed into that void, hugging the upper edge. The rear, with its Lotus script and full-width light bar fading into triangular intakes along the sides, clearly comes from the sports cars. It can glow in four colors depending on what it needs to communicate, and forms a connection with the light bar across the instrument panel. The SUV proportions and black roof are still playing tricks with our eyes, though; we can't help feeling the Eletre carries its bulk up high. The wheels are an optional set of 23-inchers that hide optional 10-piston (ten!) calipers gripping ceramic composite rotors. Lotus isn't ready to divulge specific battery capacity and motor outputs between those wheels. All we're told is the pack is more than 100 kWh and output starts at 600 horsepower. Every Eletre is all-wheel-drive, with a motor on each axle. The 800-volt electrical architecture can handle up to 350-kW fast-charging, 20 minutes at a station at that charge rate restoring 248 WLTP miles of the Eletre's estimated 373-mile range in WLTP testing. EPA numbers will come eventually. Lotus says the hauler will get to 62 miles per hour in under 3 seconds and hit a top speed of 161 mph. The electronic side mirror housings each contain three cameras, one camera for the rear views, one to help stitch a 360-degree overhead view, and one to help enable self-driving. The charge port is on the front left fender, but keen eyes might notice more shutlines atop the front wheel arches.

Lotus Esprit cancelled? [UPDATE]

Two years ago, we were gobsmacked when humble Lotus shocked the automotive world by wheeling out no fewer than five new models - admittedly in various stages of development - at the 2010 Paris Motor Show. The ambitious onslaught of new sheetmetal came at the behest of then-CEO Danny Bahar who aimed to broaden the British marque's appeal by dramatically expanding its portfolio. Bahar was later thrown out by new Malaysian owners DRB-Hicom in a management shakeup that seems to still be, well, shaking out. Bahar was deposed over accusations of financial wrongdoing and the controversial executive has fired back with a $10.6M lawsuit.
Against this chaotic background, a cornerstone of Lotus' revival plans hinged on the rebirth of its Esprit supercar (shown in 2010 concept form above). According to new reports, however, the Esprit has been cancelled, a victim of the company's uncertain finances and direction. Depending on which rumor you choose to believe, the two-seat coupe was slated to receive a house-built V8 and possibly turbocharging or hybrid power. That may all be moot now, however, as DRB-Hicom is reported to have scrapped Bahar's plans wholesale, a development that apparently includes killing off the mid-engined Esprit, too.
UPDATE: And this, friends, is why we have this story with a question mark and a Rumormill tag - Lotus is denying that the Esprit has been killed off.
