Turns out that the Honda P-NUT is not some sort of twist on the UX-3 unicycle thing we saw in Tokyo recently. Instead, the concept vehicle is a three-seat thing enclosed in lots of glass and angular lines. Honda says the P-NUT is ready for one of three possible powertrains: an efficient gas engine, a gas-electric hybrid, or a pure electric set up. There’s not a whole lot of room for any of these powerplants up front because the driver’s leg room extends almost all the way to the front of the concept. Good thing the power source is intended to be mounted in the rear.

Let’s be clear, this is a pure concept car. There are no side mirrors (but there is a back-up camera). Bumpers? Bah, Honda barely put headlights on this thing. Still, the Honda ‘Personal-Neo Urban Transport’ could make for a pretty sweet ride through a city, with lots of sight lines for the three inhabitants (a driver in the front middle, two passengers arranged behind and to either side) to see out of.

Mini brought its birthday presents to itself out to the LA Auto Show for their North American debut today. The Cambden and Mayfair were there, but we spent a lot more time ogling the Coupe and Roadster. As you may recall, Mini created these two sports cars to celebrate its 50th anniversary and showed them off alongside the two special edition Coopers at the Frankfurt Motor Show. The changes are slightly less obvious on the open-top roadster, but you can definitely see that there’s no back seat and the windshield is laid back a claimed 16 degrees over the standard Cooper. The backwards baseball cap on the coupe is a bit odd looking in pics and the real world view doesn’t do much to change that impression.

None of the display vehicles sported any detail changes but it was still fun to see all of them packed into a booth the size of Toyota’s Venza section. Ian Robertson of BMW did share a few more details about the future of MINI, with the “R60″ 4-door-4-liter-4wd about to get a real name and even more models in the works. For now we have the Coopers and Clubmen and the coupe and roadster to keep us happy. Check out the gallery below.

Buried deep within Mitsubishi’s (re)presentation of its PX-MiEV plug-in hybrid concept from the Tokyo Motor Show was a line about a global small car that Mitsubishi will be bringing to the US in 2010. That’s it, one line. We didn’t think too much of the announcement until Mitsubishi’s Product Communications Manager Moe Durand walked up and said, “In case you missed it, the small car is the Colt.” Dang!

Dang because we really like the new EVO-nosed Colt, especially in Ralliart trim. Additionally, now is a wonderful time to bring over a small car. Don’t believe us? Just ask Ford (Fiesta) and Mazda (Mazda2). The Colt will be going up against some pretty hefty (albeit lightweight) competition in the form of established B-segmenters like the Honda Fit, Toyota Yaris and Nissan Sentra.

And while we haven’t driven the new Colt, the stats aren’t exactly overwhelming – in top trim, a 1.5-liter MIVEC four-cylinder spits out 104 hp and 104 lb-ft of torque. Routed through a CVT transmission that’s probably plenty of grunt for day to day small car activities. And odds are Mitsubishi will drop a slightly buffer mill into the Colt for US duty. But just picture this – what if Mitsubishi gives us the Ralliart Colt? Maybe with a turbo. We, for one, would really be in favor of that (hint, hint). Either way, here comes the Colt.

Although Nissan and Infiniti won’t have an official presence at next week’s LA Auto Show, the luxury marque will unveil its 2011 M sedan at an event the night before the show and plans to webcast the proceedings at 7:00 pm PST on December 1.

Joining the thoroughly redesigned M on stage will be the updated 2010 Infiniti G and the oft-spied the 2011 Infiniti QX. Although official details haven’t been released for either model, a set of promo shots have already leaked out, showing a slightly reworked fascia equipped with a few organic creases, new foglamp surrounds and a tweaked grille. The QX receives a similar, although much more elaborate redesign, with a bulging hood, acres of chrome and a canted D-pillar.
