The Lotus 3-Eleven 430 is the fastest street-legal Lotus built

You're looking at the fastest street-legal Lotus ever built. Weighing in at 2,028 pounds, the new Lotus 3-Eleven 430 can hit 60 mph in just 3.1 seconds and continue all the way to 180 mph. It's a fitting tribute for 40 years of Lotus cars. As expected, the "430" in its name refers to its power output. There's no four-banger screamer in the 3-Eleven 430: The supercharged, Toyota-sourced 3.5-liter, 24-valve V6 produces 430 hp and 324.5 lb-ft. of torque. There's a lightweight carbon-composite body on an extruded-bonded aluminum chassis, and the carbon side panels are partially exposed for that cool carbon look. You also get variable, six-position traction control, with five levels ranging from 1 percent slip to 12 percent slip to off. Lateral acceleration while cornering is a respectable 1.5 g. At the Hethel test track, the new 3-Eleven 430 has reportedly beaten previous Lotus efforts. With a lap time of 1:24, it's 0.8 seconds quicker than an Exige Cup 430, and it also completely obliterates the previous, 2015 3-Eleven by shaving off 2 whole seconds. Only 20 units will be built, so few people will get to experience the 430 at maximum attack. Lotus has priced the 3-Eleven 430 at GBP102,000 on the road in the UK, which corresponds to $142,525.

Aston Martin and Lotus each issue recalls

A pair of head-turning high performance cars are catching some attention off a different kind, in the form of safety recalls. Aston Martin and Lotus have issued recalls for the V12 Vantage Coupe and Evora, respectively.
Aston Martin's affects 169 examples of the 2009-2012 V12 Vantage Coupe. It concerns the tire-pressure monitoring system, and is less a malfunction than it is a compliance issue. The TPMS does not alert the driver until the front tire is more than 25 percent below the recommended cold tire pressure. Federal Motor Vehicle Safety Standard No. 138 states that the alarm must sound when tire pressure is "equal to or less than either the pressure 25 percent below" the recommended cold inflation pressure. To address the issue, Aston Martin will notify owners and reprogram the software, free of charge.
As for Lotus, 80 supercharged Evoras have been recalled, all built between February and September, 2011. The problem involves an engine-mounted oil feed pipe, which could rupture, causing loss of engine oil or a possible fire if the oil sprays onto a hot engine.

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.
