Banned Lotus 88 F1 car explained by Colin Chapman's son

Racing teams are always looking for ways to gain speed through creative interpretations of the rule book, but speed-obsessed engineers were a little too clever with the twin-chassis design for the Lotus 88 Formula One car. Colin Chapman's son, Clive, gave Goodwood the racer's fascinating story and why the organizers banned it. Lotus' innovation with the 88 was a novel twin-chassis layout. The outer chassis supported the aerodynamic elements and the body, and the inner one held the driver, engine, and transmission. The separate pieces allowed the car to meet the rules in the pits, but the outer chassis would create a seal with the track at speed to preserve the ground effect downforce. The organizers decided this ingenious solution went contrary to the rules against side skirts, and they banned the 88. However, this Lotus was important for a second reason. The inner chassis was F1's first carbon fiber monocoque. The lightweight material is common in racing and performance cars today, but it was a cutting-edge innovation for 1981.

Lotus Elise Cup 260 celebrates the automaker's 70th anniversary

Lotus rides the special edition train nearly as often as Jeep. When you only sell a few models, you need to make the most of what you have. Today, Lotus announced a new very-limited-edition variant, the Elise Cup 260. Just 30 examples will be built and, based on pricing, it doesn't look like it will be coming to America. Hey, the cars are likely all spoken for already. The Elise Cup 260 builds on the Cup 250 and takes influence from the Lotus Evora GT430 and Exige Cup 380. Lotus says this car is even lighter than the already pint-sized Cup 250. Downforce is the name of the game with the Cup 260. The car makes 397 pounds of downforce at 151 mph (44 percent better than the Cup 250), helping the car maneuver around a circuit with copious amounts of traction. The key components here are louvered front fenders, a carbon fiber front splitter and a carbon fiber rear wing that wouldn't look out of place on an FIA-spec GT car. All of the lightweight performance options from the Cup 250 are standard equipment on the Cup 260. The sill covers, roll hoop cover, front access panel and engine cover are all made of carbon fiber. It also uses a polycarbonate backlight glass to save more weight. The Cup 260 has two-piece rotors and two-way adjustable Nitron dampers at all four corners. Strangely, the Elise uses AP Racing calipers up front and a set of Brembo clamps out back. The Elise Cup 260 is powered by a supercharged 1.8-liter inline four making 250 horsepower and 188 pound feet of torque. In the right hands, the Lotus will hit 60 mph in just 3.8 seconds. Top speed is listed as 151 mph. Lotus' Hethel track is the true benchmark of any car to wear the green and yellow badge. On it, the Cup 260 is 2.5 seconds faster than the Cup 250. The exterior has been done up in gold and features a couple of wreaths meant to commemorate the 70th anniversary of Lotus' first car. The car comes standard with Alcantara upholstery, but if it were our money we'd spring for either the yellow or red Tartan trim pack. As befitting any Lotus, weight savings was first and foremost. Things like air conditioning, carpeting and sound deadening material are all optional extras. Pricing has only been announced for Europe, but the UK base price converts to roughly $77,800. Not cheap, but few if any cars provide the pure, unadulterated driving experience of a Lotus. Related Video:

Lotus Evora GX to race in U.S. Grand-Am series

The Lotus Evora has taken many forms as a race car over the past few years, starting in 2009 with the Type 124 Endurance Racer built for the FIA GT. Since then, Lotus has developed a GT4 Cup version designed for a one-make series, the Evora GTE that currently competes in the GT class of the ALMS and the recently introduced Evora GTC.
Now, Lotus has released the Evora GX, a variation of the GTC tweaked to specifically meet the requirements of Grand-Am's new GX class that will launch at the start of the 2013 race season. While the two cars are very similar, using the same lightweight carbon fiber and plexiglass bodywork, the GX version gets a thicker U.S.-spec roll cage, a revised front splitter and bumper, a standard Grand-Am rear wing, yellow headlights and a new fuel filler system. ABS and traction control have also been removed per Grand-Am regulations.
Pricing for the Evora GX is listed at $335,000 with each one built to order, and one customer has already taken the plunge. McMahon Raceworks has placed an order and should have the car on the starting grid at the first race next year.
