2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.

A Lotus worthy of the legend | 2017 Lotus Evora 400 First Drive

Lotus is back, both literally and figuratively. After the British brand's two-year absence, the Evora 400 marks its return to the American market. It also shows what's in store as Lotus moves forward after a rough few years. We'll cut straight to the point: The Evora 400 is the best car Lotus has ever made. The heritage of the brand founded by Colin Chapman is centered around the holistic benefits of light weight and simplicity. But historically, light was a synonym for fragile. Heap on the old British build-quality stereotypes like leaking windows and intermittent electrics, and you have the Lotus reputation for brilliant but fickle cars. Owning a Lotus is a badge of honor, the car-culture equivalent of riding a fixed-gear bicycle. And while quality has improved, even modern Lotus models like the Elise, Exige, and previous Evora have a decidedly minimalist approach to comfort. That lack of modern amenities kept sales to a minimum before crash-test standards forced Lotus's hiatus from our shores. And by modern amenities we mean basics like functional air conditioning, a cabin you can climb into without pulling a muscle, and trim pieces that don't fall off from normal use. So when we say the Evora 400 is the best Lotus ever, we mean that in more than one way. It's of a material and build quality befitting the $93,785 starting price, and it retains the almost telepathic connection to the driver while increasing performance on all fronts. The 400 in the name stands for 400 horsepower. Power still comes from a Toyota-sourced 3.5-liter V6, but a new supercharger is now intercooled and delivers about 9 pounds per square inch of boost, up from 5.5 psi. It's a 55-hp jump, with a modest torque increase of 7 pound-feet, to 302. The numerical suffix, though, might suggest this is just a variant, like the Evora S was to the original Evora. Not so. Lotus says over two thirds of the parts are new, including front and rear body panels. The new Evora has a cleaner look, less like an inflated Elise and more like the mid-engine exotic that it is.

The footwell is also 3.3 inches wider. Getting in and sitting now just feels like it does in most other cars, which, for Lotus, is a revelation. Hey, there's room for a dead pedal to the left of the clutch!

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.
