VW Jetta TDI dyno shows HP loss trying to recreate cheat mode

Volkswagen is working on a fix for diesel-engined vehicles that are out of compliance with emissions regulations in the US and other countries. We're told that engineers will be presenting a solution internally sometime this month, but that doesn't mean we'll actually see it in the wild this month. One big question we have about the coming fix is, will it affect the car's performance? That question relates to another we have about the engine as it is: How much performance would the 2.0-liter diesel lose right now if it were turned down to pass US emissions? The Fast Lane Car tried to sketch some answers by going to a shop in Denver, Colorado to run a 2011 Jetta TDI with a six-speed DSG transmission on an all-wheel-drive dyno. The thinking was that if you ran all four wheels the car would think it was on the road, whereas if you ran only two the car might think it's being tested. We'll get straight to the numbers: the stock sedan is quoted at 140 horsepower and 236 pound-feet of torque. When run with all four wheels turning it produced an uncorrected 114 hp and 214 lb-ft at the wheels. When run with just two wheels in motion the Jetta got 113 hp and 188 lb-ft at the wheels. Reading the graph, we're told that power differences between the two runs were as much as 15 hp and 32 lb-ft. You'll need to take some salt with these numbers, though, because the dyno and test protocol in the video are nothing like those used by the EPA. The shop attempts to trick the Jetta into 'emissions testing mode' by using the front wheels only for the two-wheel-drive run, but we have a feeling the software code at issue is far more sophisticated than that, since the ICCT, UVA, the EPA, and CARB investigated the situation for more than a year and couldn't figure out. Also, the technician adjusts for being a mile above sea level with a correction factor of 1.2 applied to horsepower and torque, which inflates the disparity in the final power differences over the two runs. Go to YouTube and read the lengthy comments on the video left by Andrew Price for a more thorough dissection of what could explain TFL's disparities. You can watch the video above, and feel free to try and dissect the results yourselves in the comments below. Related Video:

Bentley considering diesel engine for new SUV

Turns out, in case you didn't know, the rich are just like regular people. They too are concerned about the environment, even when tooling around town in their super-luxurious Bentleys. So the automaker is weighing the idea of offering a diesel engine in its SUV offering, which could help satisfy customers' demands for more fuel-efficient engines.
Chairman and CEO Wolfgang Schreiber told Autoblog in a roundtable interview at the Geneva Auto Show that the automaker is researching whether or not a diesel engine makes sense for the brand. Bentley, owned by the Volkswagen Group, could in theory use a diesel engine from anywhere in the Volkswagen Group family. We at Autoblog have hopes they'll revive the V10 TDI used in the VW Touareg until 2010, but ever-stricter emissions laws would likely make that problematic.
But rich people aren't so much like us that they'll be worried about petty things like pricing. Schreiber admitted the diesel engine could be a $15,000 option, which he said customers would probably find "acceptable." Given that the cheapest Bentley today starts at $177,000, typical customers probably won't be diddling around worrying about an extra 15 grand.

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..
