It's not the first time we've seen diesel touted as a solution for more efficient vehicles, but Loremo AG's new eponymously-titled vehicle may just have all of 'em beat -- if it can live up to its claims, that is. According to the vehicle's designers, in addition to diesel, they relied on engine efficiency, low weight, and minimal drag to boost the fuel-efficiency, which they say could top out at lofty 150 miles per gallon. With numbers like those, it should come as no surprise that Loremo's also entered the car in the Automotive X-Prize competition but, unlike most of the other entrants, this one will apparently actually be available to the general public relatively soon. That'll supposedly come sometime next year, with Europeans the first in line to get their hands on the vehicle for the relative bargain price of €15,000 (or $22,000) -- a redesigned North American version is then set to follow a year later. As if that wasn't enough Loremo's also promising a spiffier 3-cylinder GT version that'll run you $30,000, and both hybrid and fully electric versions, although those are only described as "in the works."
