OMG: BMW Now Has DSG. They’re Calling It DCG, For “Double Clutch Gearbox”

I took a little drive this weekend to see a friend and kept my speed around 65 to see what would happen to my gas mileage. I hit and stayed at 30 MPG…in a car that has 330HP and 330ft/lb of torque (BMW 335i). I was really pleased with my car this weekend; it was fun as hell to drive on the roads I was on, and knowing it was fairly efficient just made it that much better.
Anyway, it got me thinking about cars for a moment so I decided to go price a 335i and an M3 for giggles. That’s when I noticed an option on the M3 that I’d not seen before–the “M Double-clutch Transmission with Drivelogic”. Hmm, what is this I wondered…
Turns out it’s the BMW version of Volkswagen’s DSG. This thing is utterly sick. It’s a transmission with two clutches. As you move through the gears a second clutch remains open and waiting for you to switch into the gear above or below the one you’re in. So when the change happens (which is anticipated by the computer), it happens almost instantly because the other clutch has already rev matched your other gear.
Do has boner.
