Yeah, it's more than 10 better | 2018 Lotus Evora Sport 410 Quick Spin

Doesn't it drive you crazy when you get a new toy and within weeks they announce a new, improved version? That's exactly what Lotus has done with the new Evora 400. Just as this two-plus-two coupe is wowing US buyers with its combination of light weight and old-school ride and handling, those sneaky devils have gone and produced a lightweight, sport version. Your correspondent attended the launch to test the waters, but in the process found that you'll still have time to enjoy your stock 400 model, since the Sport won't be gracing US shores before next summer – Lotus still has to engineer its lightweight construction for US safety regulations. And will you then want to swap for one at a likely price in excess of $105,000? Read on. Not if you plan to carry the kids, since the new Sport 410 is now strictly a two-seater. The vestigial rear perches, along with the air conditioning, stereo wireless, rear bulkhead glass, sound insulation, door trims, and even the mud flaps have been jettisoned to reduce mass. As a result, you can't see much out of the rear-view mirror except carbon-fiber stays. Other weight-saving measures include new carbon-fiber panels for the roof, rear deck, and front and rear panels. There's a new lithium-ion main battery saving 25 pounds and an optional titanium exhaust system that's lighter and sounds saucier. Total weight saving is 154 pounds compared to the 400, which makes the curb weight a feather-like 2,923 pounds despite the addition of a new transmission oil cooler. It pushes itself into the ground harder, too. Aerodynamic tweaks such as the front splitter and rear spoiler increase downforce from 19 pounds to 40 at 100 mph and from 71 pounds to 141 at 150 mph. Lotus has tweaked its inlet-charge-cooled and supercharged 3.5-liter V6 Toyota Camry engine to yield 10 extra horsepower for a total of 410 (hence the name) at 7,000 rpm and 302 pound-feet of torque at 3,500 rpm. The 410 will hit 60 mph in 4.0 seconds with the six-speed manual, or in 3.9 with the six-speed automatic. Suspension adjustments include re-valved dampers and an effective spring-rate increase thanks to the lighter weight. The hydraulically assisted steering and AP Racing brakes with two-piece rotors remain the same, as does the geared Torsen-type limited-slip differential. The Sport runs on specially forged Magnesium lightweight wheels shod with Michelin Pilot Sport Cup 19/20-inch tires front/rear.

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.

Lotus stepping up to LMP1 in World Endurance Championship

Only a couple of years ago, it looked like the top tier of prototype endurance racing was in trouble. Peugeot shut down its program, leaving the LMP1 category all to Audi to dominate. Only six cars entered the Petit Le Mans in 2012, and the season was cut short. But the top class in the FIA World Endurance Championship has since blossomed. And it only looks poised to grow further.
Audi and Toyota will each be back on the grid this season, joined by Porsche. But the latest news has Lotus stepping up to the big leagues also. (Well, sorta: the German-run squad uses the Lotus name and colors, but has no more to do with the automaker than the Formula One team of the same name.)
The Lotus LMP1 will be based on the same Lola-based T129 chassis used until now in the LMP2 class, with former F1 driver Christijan Albers leading the driver lineup. In addition to Audi, Toyota and Porsche, the solitary Lotus entry will also compete against privateer Rebellion Racing in a nine-car LMP1 grid throughout the season.
