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.

Volkswagen Caddy hauls its cute self into Geneva

Here in the States, we have a small but growing segment of little people-and-stuff-carriers, including new things like the Ford Transit Connect, Nissan NV200, Ram ProMaster City, and so on. But in the Old Country, these little guys are everywhere, and hardly a new concept. One of Europe's best in this segment – the Volkswagen Caddy – has been given a thorough refresh, combining all of the great-to-drive characteristics of a Golf with the functionality of a Touran van. Buyers can choose between four different versions of the 2.0-liter diesel inline-four, or three gasoline engines in 1.0-, 1.2-, and 1.4-liter displacements. There's even a natural gas version. And with its Golf roots, your author is, shall we say, really, really interested in a GTI version of this little cutie. The Caddy you're seeing here is, obviously, a passenger van configuration with windows abound. Buyers can also opt for a panel van variant, for more secretive load-hauling. Have a look at the updated Caddy in the images above, and read all about it in the release below. The new Caddy – always the best choice – world premiere for the fourth generation of the best-seller - Entry-level price reduced due to new versions - Emissions and fuel consumption reduced by new EU6 engines - Safety increased by new driver assistance systems - Design refined with clear edge Hannover/ Poznan, 04 February 2015: Volkswagen Commercial Vehicles is showing the fourth generation of the hugely popular Caddy for the first time. Around 1.5 million of the award-winning previous generation were sold worldwide during its eleven years in production. A success that the new Caddy is intended to continue because the urban delivery van and its privately used brother have been enhanced and refined in every area. In Germany, prices for the new Caddy start at ˆ 14,785.00 (net, panel van) and ˆ 15,330.00 net (ˆ 18,242.70 gross, as Conceptline, replacing the previously familiar Startline), each with the 62 kW TSI entry-level engine and thus, when adjusted for feature content, are even below the level of the predecessor model. The drive systems use state-of-the-art technology, with the Caddy's new engines providing maximum efficiency and compliance with the EU6 emissions standard. The basis for the four TDI diesel versions is always a two-litre four cylinder engine. Their performance ranges from 55 kW / 75 h.p. to the top engine with 110 kW / 150 h.p..

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.
