VW to unveil diesel-electric Twin-Up! in Tokyo

We've received multiple reports that Volkswagen will be bringing a diesel-electric concept to the 2013 Tokyo Motor Show, set to take place later this month. The car, called the Twin-Up!, is based on the Up! city car, with some sources claiming this is a thinly veiled concept that will eventually enter production.
According to Automotive News Europe, the Twin-Up! will reportedly return 214 miles per gallon on the US cycle by combining an 800-cc, two-cylinder diesel and an electric motor. It will also boast plug-in capabilities, and will be able to cover 30 miles on electric power alone.
Autocar has a more complete picture of the Twin-Up!'s powertrain, though, claiming it's a modified version of the hybrid system found in the Volkswagen XL1. The Twin-Up! will get a more potent, 47-horsepower electric motor to the XL1's 27-hp unit, but will retain that car's 47-hp turbodiesel. The battery pack will also grow, from 5.5 kilowatt hours to 8.6 kWh. Both of these increases are necessary due to the increased weight of the Twin-Up! - it's some 900 pounds heavier than an XL1.

An inside look at VW's new California R&D center

Less than two months ago, the Volkswagen Group opened a new facility in Oxnard, California (about an hour's drive west of Los Angeles). The $27 million investment, touted as Test Center California (TCC), serves as a research and development lab testing emissions for all brands under Volkswagen's umbrella, including its newest member, Porsche. While still not fully operational, we toured the new 64,000-square-foot building last week and had a first-hand opportunity to see just how much work is involved testing engines and meeting increasingly stringent government emissions standards.
Replacing a similar facility established in 1990 in Westlake Village (about 20-minutes east of the new location), our guide explained how Oxnard was chosen for its temperate climate, varied regional terrain for test drives and low altitude. (The area is only a few feet above sea level - a critical parameter when instrument testing emissions.) The new facility is capable of analyzing hundreds of vehicles, prototypes and customer-owned vehicles, annually.
Most interesting to us was the huge stainless steel climate chamber, with a massive four-wheel dynamometer that allows VW to test running vehicles in both scorching desert and freezing climates without ever leaving the building (an Audi Q7 was running in place during our visit). We were also mesmerized by the countless storage tanks and intricate plumbing of chemicals, stored in both liquid and gas states, needed to perform the variety of tests. Lastly, we took a look at Bugatti's service center on the west coast, located completely within the new center. While there were no supercars on site, the facility is equipped with plenty of spare forged wheels (mounted with expensive Michelin PAX tires) and a Veyron-specific repair jig that allows the vehicle to be completely disassembled, if needed. It is a shame that the facility, which set off all of our automotive geek alerts, is closed to the public.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.
