Ultra-rare Maybach 57S Coupe ordered new by Moammar Gadhafi is for sale

One of Maybach's rarest 21st-century cars is for sale in Holland, and it owes its existence to one of the most controversial African leaders in recent history. Dutch exotic car dealer Auto Leitner listed a Xenatec-built Maybach 57S Cruisero coupe ordered and customized by Colonel Moammar Gadhafi but built after his death. Short-lived German coachbuilder Xenatec chose to start with the short-wheelbase 57 rather than with the longer and more stately 62. It didn't alter the sedan's length or wheelbase; instead, it created the Cruisero by extending the front doors, removing the rear doors, and adding more rake to the roof pillars. Several other minor visual tweaks set the coupe apart from the sedan, and the interior was given a more superficial makeover. Xenatec made no mechanical modifications, so power comes from an AMG-built 6.0-liter V12 twin-turbocharged to 604 horsepower and 738 pound-feet of torque. It spins the rear wheels via a five-speed automatic transmission. Although the coupe weighs 6,000 pounds, it takes five seconds to reach 60 miles per hour from a stop. The 57S Coupe was not a hefeweizen-fueled hack job haphazardly welded together in a shed. It was authorized by Daimler, and it was engineered to the same standards as the regular-production car. Executives were confident that they could sell 100 units to politicians, entrepreneurs, oligarchs, and other wealthy people around the world, but Xenatec filed for bankruptcy and closed after making only eight when one its main investors, a Saudi Arabia-based company named Auto Kingdom, abruptly stopped funneling money into the project. Gadhafi configured Auto Leitner's 57S Coupe, which was the fourth one built, and he should have taken delivery of it in 2012, but the Libyan Civil War that erupted in 2011 and ultimately led to his death on October 20 of that year derailed those plans. It was instead sold to another buyer whose identity is unknown. What's certain is that the person who ended up with Gadhafi's Maybach rarely drove it: its odometer shows about 1,429 miles. Highly optioned, this 57S is equipped with 20-inch wheels, soft-close doors, heated and massaging individual rear seats separated by a fridge, rear tray tables, front and rear air conditioning systems, a rear-seat entertainment system, and, for good measure a fire extinguisher.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.
