Volkswagen throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

UAW tactics called into question at VW's TN plant

The United Auto Workers is in hot water with some of the very workers it is trying to unionize at Volkswagen's Chattanooga assembly plant. According to The Tennessean, eight Volkswagen factory workers have filed complaints against the UAW with the National Labor Relations Board, claiming the union "misled or coerced" them into formally asking for union representation.
The UAW has instituted a major push at the Chattanooga plant to represent the 2,500 hourly laborers that build the VW Passat by using what's called a card-check process. The tactic is opposed by the National Right to Work Legal Defense foundation, the group representing the workers. The card-check process demands that a company recognize a union that obtains the signatures of more than half its workforce, according to The Tennessean. This tactic is in contrast to the more traditional route, which sees employees vote on union representation.
The workers filing the complaint claim that the UAW told them the cards merely called for a secret ballot, rather than an outright demand for union representation. Workers also allege that the UAW has made it overly difficult to reclaim their signed cards, some of which were signed so long ago that they have been rendered invalid. Although the cards can force a company's hand, federal law still allows the company to ask for a secret ballot before yielding to unionized workers.

Cruze Diesel Road Trip reveals the good and bad, but no ugly

Most of us have strong opinions on diesel-powered cars based on our perceptions of and experience with them. I used to thoroughly dislike oil burners for their noise, smoke and lackluster performance, and the fact that they ran on greasy, smelly stuff that was more expensive than gasoline, could be hard to find and was nasty to get on your hands when refueling. Those negatives, for me, trumped diesel's major positives of big torque for strong acceleration and better fuel economy. Are any of those knocks on diesel still valid today? I'm not talking semis, which continue to annoy me when their operators for some reason almost never shut them down. At any busy truck stop, the air seems always filled with the sound – and sometimes smell – of dozens of big-rig diesels idling endlessly and mindlessly. Or diesel heavy-duty pickups. Those muscular workhorses are far more refined than they once were and burn much less fuel than their gasoline counterparts. But good luck arriving home late at night, or departing early morning, without waking your housemates and neighbors with their clattery racket. No, I'm talking diesel-powered passenger cars, which account for more than half the market in Europe (diesel fuel is cheaper there) yet still barely bump the sales charts in North America. Diesel fuel remains more expensive here, too few stations carry it, and too many Americans remember when diesel cars were noisy, smelly slugs. Also, US emissions requirements make them substantially more expensive to certify, and therefore to buy. But put aside (if you can) higher vehicle purchase and fuel prices, and today's diesel cars can be delightful to drive while delivering much better fuel efficiency than gas-powered versions. So far in the US, all except Chevrolet's compact Cruze Diesel come from German brands, and all are amazingly quiet, visually clean (no smoke) and can be torquey-fun to drive. When a GM Powertrain engineering team set out to modify a tried-and-true GM of Europe turbodiesel four for North American Chevy Cruze compacts, says assistant chief engineer Mike Siegrist, it had a clear target in mind: the Volkswagen Jetta TDI 2.0-liter diesel. And they'll tell you that they beat it in nearly every way. "I believe we have a superior product," he says. "It's powerful, efficient and clean, and it will change perceptions of what a diesel car can be." The 2.0L Cruze turbodiesel pumps out 151 SAE certified horses and 264 pound-feet of torque (at just 2,000 rpm) vs.
