Lotus Emira First Edition starts at $85,900

Last October, Lotus priced the Emira V6 First Edition at $93,900 before destination and taxes. That coupe comes with a Toyota-sourced 3.5-liter supercharged six-cylinder making 400 horsepower and 310 pound-feet of torque when fitted with a six-speed manual gearbox, or 317 lb-ft when fitted with a six-speed automatic. Now, the automaker's finally put numbers to the Emira First Edition with the AMG-sourced four-cylinder; it makes 360 hp and 310 lb-ft and costs $85,900 before incidentals. The MSRP is $8,000 less than the forerunner, but $3,000 more than the standard series Emira V6. Copying the template of the Emira V6 First Edition, the four-pot throws in a bunch of extra gear at no cost. The Lower Black Pack, Drivers Pack, Design Pack, and Convenience Pack are included. Twenty-inch diamond-cut two-tone wheels are standard, but silver or gloss black finishes are no-cost options, as are brake calipers in either black, red, silver, or yellow. All the mod-cons in the Emira V6 are here in the Emira, from the 12.3-inch digital gauge cluster and 10.25-inch infotainment screen to the climate control, navigation, and 340-watt KEF audio. Six exterior colors include Dark Verdant, Hethel Yellow, Magma Red, Nimbus Grey, Seneca Blue, and Shadow Grey. The interior offers seven hues, four in various leather shades and three in Alcantara with contrasting stitching. The meat of the matter is that inline-four bought from Germany. Lotus said the AMG M139 motor's been tuned at Hethel for the Emira, its hardware and software tweaked for placement in the middle of the vehicle and to provide a proper Lotus experience. The exhaust is also a Lotus design. It's mated to an eight-speed dual-clutch transmission that's also seen English revision for work in a rear-wheel-drive sports car.  The only way to tell the Emira apart from the Emira V6 would be to get close enough examine the engine cover or read the badge on the C-Pillar. Perhaps handling or exhaust tuning will put them farther apart, but the initial performance specs don't. The Emira is 0.1 second slower to 60 miles per hour than the Emira V6, and maxes out 4 mph short of the Emira V6's 180-mph top speed. That's not a lot of daylight for an $8,000 price difference. The configurator is up now, so shoppers can make up their own minds.

Race Recap: 2013 Bahrain Grand Prix follows the template of this year and last [spoilers]

The sand, the wind, the penalties, the contact and the one crash - all of them collided to make the Bahrain Formula One Grand Prix a surprise affair from day to day and lap to lap. Oh, and did we mention the tires? Pirelli made a last-minute swap after the amusement park ride that the Chinese Grand Prix turned into with the soft compound tire, and brought medium and hard compounds to the desert. That didn't stop things from falling apart for some teams - literally - and that didn't stop the one team that seems to love the hard compound Pirelli tire.

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.
