The 11 most expensive American cars ever

Here's a Pro Tip for all you would-be classic car investors out there: buy Ferraris. With the Pebble Beach festivities kicking off this week, including any number high end car auctions, we thought it would be entertaining to compile a list of some to the most expensive cars ever sold with the bang of a gavel. Trouble is, once you get past the splendor of everyone's favorite Italian sports car maker, that list is pretty boring.
Ferrari dominates the all-time auction sales list; seven of the top ten most expensive cars sold wear the Cavallino Rampante badge, as well as more than half of the top fifty. Sure, a nearly $30-million Mercedes-Benz W196 racecar might be the new top dog as of last year, but it's even possible that Ferrari could take that title back in Monterey this weekend. Long story short: we think a list of the most expensive American cars ever sold at auction is a lot more entertaining to read. Hell, our list has a friggin' Batmobile on it, how can it go wrong?
Follow on below for the top ten cars that are red, white, blue and a whole lot of green.

Ford Figo concept unveiled in India

Ford has officially unveiled the Figo Concept at the 2014 Auto Expo in New Delhi. While it may wear a concept badge, we'd argue this little sedan, which is under 12 feet long, looks ready to replace the current Figo and do battle with other B-segment cars in the world's emerging markets.
"With the Figo Concept, we are showing that choosing a compact sedan does not mean compromising on premium design or smart solutions," said Kumar Galhotra, Ford's VP of engineering, global product development. That premium design includes Ford's familial, trapezoidal grille and Fusion-esque headlights in front, while the rear end reminds us of the last-generation Focus Coupe. While that car wasn't exactly attractive, the chopped off tail looks pretty nice on this smaller car. And if you really don't like the looks of the Figo Concept, just remember - it looks better than the current production model. Aerodynamically, the Figo's shape is quite slippery, which means reduced wind noise and improved fuel economy.
As for the "smart solutions" touted by Galhotra, the narrow confines of Indian streets make driving even the tiniest cars a challenge. To give the Figo Concept a one-up on the competition, Ford has fitted power-folding mirrors that sport a "flexible architecture," which should stand up well to bumps from cars, people or bikes. We don't have any interior images, but Ford is promising a large cabin, that includes a dock that can accommodate a phone or MP3 player, allowing either to be controlled through the car.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
