Progressive Automotive X-Prize competitors roundup

With about three weeks left to go, the Progressive Automotive X-Prize has already got 25 submissions (20 names have been publicly released) with creators ranging from college students to large auto makers already in the game. Here's the deal with the contest: the cars must be production-capable and fall in with federal safety guidelines, and it's got to be possible to produce and sell 10,000 of them annually, with a working business plan in place for this to happen by 2014. The car must deliver at least 100 MPGs, and CO2 emissions can't exceed 200 grams per kilometer. The prize for the competition is ten million dollars. We've seen some of these in the past -- Aptera's 2e, MDI's AirCar, and the Tata Nano are all on offer -- but there are a few new guys, too. Some of the more interesting entries are the totally rad looking diesel Avion which has gotten up to 103.7 miles per gallon, Kinetix Motors' diesel-electric hybrid E4 Sports Hatch, which should cost less than $25,000 with a top speed of 95 miles per hour. The company also claims the sporty ride goes from zero to sixty miles in 6.1 seconds. Finally, there's Physics Lab of Lake Havasu Green Giant, an electric truck that gets 50 miles per gallon on its battery, with plans to bump that figure to 100 miles per gallon using other sources of energy. Check out the gallery of other prospects, and hit the read link for the full, delicious list.

Tazzari Zero's preliminary specs released

Italian industrial firm Tazzari has announced preliminary specs and launched a new website for its plug-in auto, the Zero. Measuring 113.5 inches long and sporting 15-inch wheels, the city-bound electric car weighs in at 1,200 pounds -- 312 of that from the lithium-ion Fe battery. It'll handle 88 miles with a full charge that takes 9 hours to fill, but you can reportedly juice up to 80% in just 50 minutes. Top speed is 56 MPH, so don't expect to be driving this on the highway, and it can go from 0 to 31 in under 5 seconds. The company says it's due out later this year in Europe and the Carribean for less than 20,000 Euros ($25,760), and yes, there's a dozen Crayola-inspired colors available. Hit up the official site for a trailer.

Takeoka Jidosha Kogei's electric minicar gets slightly more macro, even more cute

Japanese minicar manufacturer Takeoka Jidosha Kogei's Milieu R is the perfect car for anti-social folks, featuring only one seat and a range of 50km that's just enough to make your commute while being limited enough to get you out of going to the bar afterward. Thus far those who socialize only with (very) small animals have been left out of the company's offerings, but that all changes with this new prototype, the T10. It's ever so slightly larger, gaining 90mm in length and 40mm in width, making room for a shelf to the left of the driver's seat intended for some sort of pet (we're guessing hamster, possibly a petite guinea pig). The other specs, including that 50 km range and top speed of 55 km/h, stay the same, meaning there'd still be no concerns about getting to work early or having to socialize afterward, but we're not sure its charming looks make up for a price tag set to be somewhere north of ¥856,000 (about $9,520); awfully close to that of a "real" car. At least it looks a little safer than the HUVO.

Luxury cars for under $30,000

The conventional wisdom, among most folks, anyway, is that buying a used car is usually something done out of necessity, by those on a budget -- that is, people who want, or need, to "move down" from the new-car market because a new model is simply out of their reach.

Bottom line, the Lexus reputation is for high-end luxury, quality and long-term dependability.

However, there is another category of used cars that appeal to those with a bit more disposable income: used luxury cars.

For some buyers, the used-luxury market is a way of getting into that Lexus, Lincoln, Infiniti or Porsche you always wanted, without laying out $70,000 or $80,000 for something you're not actually going to live in.

For others, scouring the used-luxury-car listings is a way of re-visiting the halcyon years of their youth. At this point, some of these used-luxe models have been around so long that they almost qualify as vintage throwback editions.

Recently, Consumer Reports magazine issued its list of best and worst used cars, and divvied them up by price range. Using CR's recommendations as a guideline, here is a list of some of the best used luxury cars currently on the market in the $24,000-30,000 price range.
