Volkswagen formally introduces super-efficient XL1

Lightweight and low drag are hallmarks of great sportscar design. But when paired with a super-efficient, hybrid powertrain, you have the Volkswagen's XL1 that has been formally introduced in Geneva today.
When the 1,700-lb, carbon-fiber-bodied two-seater hits the road, its claimed 261 miles per gallon will make it the world's most-fuel-efficient production car. Though "production car" might be a stretch since VW said in a February press release that the XL1 would be built using "handcrafting-like production methods." We translate that to mean you won't be seeing many of these cars on the road. Though no one at VW has mentioned pricing yet, early rumors suggested a six-figure price tag.
That's supercar budget for a vehicle that has a 47-horsepower, two-cylinder diesel engine and a 27hp electric motor. With numbers like that, owners can expect 0-62 mph times of 12.7 seconds and top speed near 100 mph.

How VW's hyper-efficient XL1 will influence the next Golf

In 2007, the European Union mandated fleet average CO2 emissions of 158.7 g/km. For 2015, that figure will drop to 130 g/km, and the target for 2020 is an ambitions 95 g/km. Thanks to some German politicking, that target will be phased in from 2020 to 2024, but it will still apply to 80 percent of passenger cars in that first year. In US miles per gallon, that's the equivalent of going from about 35 mpg to 42 mpg to 57 mpg. The current Volkswagen Golf is rated from 85 g/km of CO2 to 190 g/km depending on model - and zero for the e-Golf, so for the next-generation MkVIII hatch due in 2019, to meet the goal, Volkswagen engineers will need to introduce a bunch of new tricks. According to a report in Autocar, VW be mining its hyper-efficient XL1 for some of them.
Predictions for the next Golf include a variable-compression engine, an electric flywheel and an electric turbo, along with taking greater advantage of coasting. Volkswagen could be getting help from Audi with the electric turbo and variable-compression engine and electric turbo, with Audi already having shown off the former and brand technical boss Ulrich Hackenberg confirming the VW Group is working on the latter. It's possible the flywheel system could also have the mark of The Four Rings: Autocar mentions a British system that Volvo is testing, but the R18 e-tron Quattro racer has been using one for years.
The need for such features is because the company won't be able to net enough future gains from just aerodynamic improvements and advanced materials. As price will be a factor (the regulations are expected to "add hundreds of euros to the cost of building a car"), adding much more aluminum or carbon fiber is an unlikely option. We're told the next generation won't be longer or wider than the current car, and being Europe's most popular model, VW doesn't want to make a big bet on futuristic aero, but the report says the MkVIII will "likely" have "the most aerodynamic treatment yet seen on a production vehicle," the area where lessons learned from the XL1 will truly be seen.

Interested, then not: Marchionne not 'chasing' a VW merger

Update (March 15, 2017) : Automotive News reports that FCA CEO Sergio Marchionne, regarding the suggested VW and FCA merger, said in a press conference "I have no interest." He also said that he "will not call Matthias," the CEO of VW. He did add that he would be willing to entertain anything VW brings up, but he has "no intention of chasing him." Despite this, Marchionne still took a moment to reinforce his favorable stance concerning mergers and consolidation. Last week, Volkswagen's CEO Matthias Mueller effectively shut down Fiat Chrysler CEO Sergio Marchionne's idea of the two automakers merging. However, it seems Mueller has softened, if only just, to the idea. According to Reuters, the CEO said in a press conference he is "not ruling out a conversation." However, he did say that he would like Marchionne to discuss with him directly the possibility rather than to the media. Though this statement certainly doesn't mean such a merger is happening, it's far more open than when he said outright the company isn't in any talks with anyone at the moment. His new stance also indicates that there may be people (lawyers, accountants, etc.) behind the scenes working out possible ways a merger could work. And even though this new development makes the prospect of a merger between the two companies a bit less bleak, it's still a long way from the "will they, won't they" relationship between GM and FCA. FCA's pursuit of GM involved emailing CEO Mary Barra and the threats of a hostile takeover, the latter of which resulted in some awkward statements about hugs. Only time will tell if VW becomes open enough for Marchionne to talk about hugs again. Related Video:
