Jay Leno goes old school with 1966 Lotus Elan 26R

On the latest episode of Jay Leno's Garage the guest's are both from inside the garage: the man they call Professor Jim Hall, Leno's master fabricator, and the 1966 Lotus 26R that he spent 18 months building. The Elan 26R was the racing version of the Elan that Lotus founder Colin Chapman began building after watching privateer teams prep their roadgoing Elans for competition duty all over Europe. Built by the factory from 1964-1966, drivers like Jim Clark and Jackie Stewart won silverware in the roadster called "the giant killer."
Hall, a veteran Lotus wrench, started with the 1966 Elan street car and turned it into a 26R that's arguably better than the factory original. Except for the engine block and head, original 26R body and Elan chassis, just about everything is custom built, highly modified or special order, from the fabricated oil pan, brake lines, safety wiring and oval exhaust tubing to the six-speed sequential transmission.
The episode is an unusually-long 21 minutes because, as an in-house build, Leno can go through the process of putting the whole roadster together. When he takes it for a drive and keeps going on about how it sings, you can hear it, too. It's worth the time to check out Mr. Hall's Opus in the video below.

2017 Renault Alpine still looks like a Lotus

Two years ago, an oddly modified Lotus Exige was photographed speeding around the Nurburgring. While that car looked British, at the time Renault's engineers were reportedly developing the suspension for the future Alpine sports coupe underneath with some help from the folks at Ohlins. Now, our spies have spotted this weird Lotus-bodied mule out testing, and it might be a major hint that development for the reborn French brand is getting serious again. Unfortunately, it's hard to pull many details about the future Alpine just from this mule. Up front the air extractors are noticeably covered, and at the rear there's now a panel hiding the engine with just some small vents near the very back. The roof-mounted scoop appears to be the major means of sending cool air to the powertrain. Alpine has been back in the news as of late. At the 24 Hours of Le Mans, the brand's Celebration Concept was unveiled but without many real details. Then, at the Goodwood Festival of Speed, the car was filmed actually moving under its own power. Earlier reports suggest that a production version, possibly called the AS1, might come in 2017 with around 250 horsepower on tap from an engine mounted behind the driver. Engineers would keep weight as low as possible to make the most from that power. While no version in the US is likely, prices in Europe might be about the equivalent of $34,000 to $40,000.

Lotus Evija's wild aero setup is detailed by chief aerodynamicist

The Lotus Evija is a car of firsts for Lotus. To that end, the company has spent a lot of time talking over the details. Today, we get to learn about the wild shape’s aerodynamics and what Lotus engineers were trying to accomplish. Richard Hill, chief aerodynamicist for Lotus takes a dive into all the details, and the video at the top of this post offers a great visual. “Most cars have to punch a hole in the air, to get through using brute force, but the Evija is unique because of its porosity,” Hill says. “The car literally ‘breathesÂ’ the air. The front acts like a mouth; it ingests the air, sucks every kilogram of value from it – in this case, the downforce – then exhales it through that dramatic rear end.” We can see what Hill means as we look at the Evija in photos. Instead of a regular front bumper, this one has pass-throughs that direct the air back into the side of the car. Lotus hasnÂ’t released the all-important coefficient of drag figure yet, but we have to imagine itÂ’s very low. The front splitter (below, left) is responsible for a few different things. The opening in the center takes in air to cool the battery pack that is mounted behind the seats. Then, the outer section of the splitter channels the air to the “e-axle” for cooling of the electrical components. And finally, it also produces downforce.  There are a couple more tunnels for air to pass through in the rear. These “holes” are likely the most distinctive design feature, especially when accentuated with the LED taillights. Hill says that these are also fully functional and help to reduce drag. “They feed the wake rearward to help cut drag,” Hill says. “Think of it this way; without them the Evija would be like a parachute but with them itÂ’s a butterfly net, and they make the car unique in the hypercar world.” On top of all these porous body structures, there are pieces that move. The rear wing can elevate upward from its flush body position and deploy into clean air above, creating more downforce. And then thereÂ’s an F1-style drag reduction system. This uses a horizontal plane that deploys from the car to make it slipperier through air. The final big piece of this puzzle is the underbody sculpting that directs air into the massive rear diffuser. This causes an upwash of air, in turn creating a massive amount of downforce. Hill sums it up quite nicely.
