To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

2015 Volkswagen Golf SportWagen First Drive [w/video]

Volkswagen currently offers five Golf models in the US, and in just a few weeks it will add the 2015 SportWagen to the lineup. The previous version sold as the Jetta SportWagen, although it was technically a Golf. For the new model, VW product planners decided to align all the hatchbacks under the same name. The SportWagen employs the same engines as the Golf, but significantly stretches its new MQB architecture. The result is greater practicality in the form of cargo room. With the seats up the SportWagen holds 30.4 cubic feet, almost 8 more than the Golf. The gap widens to nearly 14 cu ft with the seats folded; a max capacity of 66.5 cu ft puts the SportWagen into compact crossover territory. That added functionality leads VW to think it can sway buyers shopping the likes of the Honda CR-V and Toyota RAV4. And with the high-mpg diesel variant – 31 mpg city, up to 43 highway – VW hopes to lure those considering fuel-sipping MPVs like the Toyota Prius V and Ford C-MAX. What separates this Golf from those other two segments is the driving prowess we've come to expect from Wolfsburg's best-selling nameplate. While the silhouette is similar to the outgoing Jetta wagon, designers honed the character lines to give the Golf SportWagen a more modern, angular aesthetic. The LED headlights look sharp, the hood now scoops down at a steeper angle into the front fenders, and the general proportions – in line with other Golf models – have changed. The new SportWagen is lower, longer, and wider and than the Jetta SportWagen it replaces. Specifically, it is 1.1 inches longer, 0.7 inches wider, and despite being about an inch lower, actually boasts more headroom. Inside, things look pretty familiar to the current Golf family. There are small, premium touches such as a sporty, flat-ish-bottom wheel, piano-black trim, and an optional one-touch panoramic sunroof that makes the cabin a bright, airy, and pleasant place to be. Otherwise, it's your standard Golf fare, but with a whole lot more room out back. The same two engines that power the standard Golf – the 1.8-liter turbocharged inline-four TSI, and 2.0-liter turbocharged TDI diesel – are also found under the hood of the SportWagen. Gasoline-powered models come with a five-speed manual or a traditional six-speed auto, while the TDI gets six-speed transmissions across the board – either as a row-your-own manual, or a dual-clutch DSG auto with steering wheel-mounted paddles.

Sunday Drive: Variety is the spice of life

If there's any one new vehicle the entire world is anxiously waiting for, it's the Jeep Wrangler. Yes, of course the iconic off-roader has a loyal following here in America, but you could plop a Wrangler pretty much anywhere on the globe and everybody will know what it is. Put simply, the redesigned 2018 Jeep Wrangler JL has big, muddy shoes to fill, and the readers of Autoblog are just as interested in the Wrangler's rebirth as anyone else. Moving along, we were fortunate enough last week to spend a bit of time in nearly every version of the venerable Volkswagen Golf all in one day. There isn't a Golf we don't like, but there's one, easily identifiable by its three-digit name, that stands above all the rest: GTI. We think it's the best Golf you can buy, even if there's an R-badged variant that slots above the GTI in VW hierarchy. Rounding out our recap are three vehicles that could hardly be more different. The 2019 GMC Sierra, which was seen wearing pretty light camouflage, is a truck. The Lamborghini Terzo Millennio – which isn't going to go on sale, ever, at any price – is a conceptual supercar. And the Honda CB1000R is a retro-themed naked standard motorcycle.
