The Evora Cup doesn't have much relevance to you unless you're going to move to Europe and race in Lotus' 2010 GT4 manufacturer series. Actually, though, with a prize fund of "at least 100,000 euros," maybe you should look into it if you have some skill.
Full details on the Lotus Evora Cup car won't be released until the 2010 Geneva Auto Show in March, but already we know it will have an enlarged 4.0-liter version of the Toyota 2GR-FE V6 with dry-sump oiling.
Lotus estimates the mid-mounted V6 will develop about 400 horsepower at 7,000 rpm and about 295 pound-feet of torque at 6,000 rpm. Redline will be 7,250 rpm. The Cup car is supposed to weigh under 1,200 kg (~ 2,645 pounds). The transmission will be a Cima 6-speed dog box with paddle shifters.
The car will have an aero package with a carbon fiber front splitter, diffuser and rear wing developed by Dallara. Running gear will include adjustable dampers and more serious brakes with two-piece aluminum rotors, and six-piston calipers up front and 2-pots in back.

NICE power figure for a NA V6. (You see that BMW?) Lotus is one of the reasons that Toyotas motors are respected like they are. Not only do they last forever, but if you want power out of them, you can get it.

The Evora is a great looking car - it's on my list.
"6-speed dog box" ?? Not familiar with the term, is this a DSG??

@-rick8365
A dog box is the term for a transmission utilizing a dog engagement (opposed to synchronizers mesh gears). A dog box can have either helical or spur gears or both
What is dog engagement? Dogs are basically no more than cogs on a slider. The shifter pushes them into a receiver ring which engages the gear it is attached to. There is a separate dog and receiver for each gear in the transmission. On a racing transmission, there is a lot of "slop" (the gaps in the receiver are a lot larger than the teeth on the dog), which makes it easier to move into and out of the gears at higher RPMs without fully engaging the clutch.
Difficult for street use…more of a racer application.

I'd normally be pretty nervous about a 4.0L V6 being harsh at high rpm IF it wasn't this Toyota V6. Should be a cracking car.

@firstclass, does that mean the dog box trans comes equipt with "poodle" shifters?

It's no Espirit, but I'll take it.
