VW Tiguan grows up, gets bigger

The compact crossover segment continues to do huge business around the world, and Volkswagen is showing just how important the niche is by debuting four versions of the all-new, second-generation Tiguan at the Frankfurt Motor Show. Now riding on VW's MQB platform, the latest version has had a growth spurt, but it has also shed 110 pounds in the process. The first of them will hit the international market in April 2016. While the design is still definitively a VW, the latest Tiguan looks more aggressive and expands to 2.4-inches longer, 1.2-inches wider, 1.3-inches lower. There's also three more inches of wheelbase than the outgoing generation. At the front, the grille stretches all the way across and connects with the headlights to visually widen the look even more. In profile and at the rear, things are now a bit more angular, but the changes give the model a more chiseled style. In Fall 2016, VW will debut an even longer wheelbase body for the Tiguan. According to the company, this version will be aimed directly at customers in the US and China that prefer larger vehicles. The added inches outside translate to more room for passengers and cargo inside. Even with the seats up, there's an extra 1.8 cubic feet for stuff in the back, and those sitting in the rear get 1.1 inches more knee room. As an added amenity, buyers can option a 12.3-inch Active Info display digital instrument panel. Europeans gets a choice of eight engines: four fueled by gasoline and four by diesel. They range in power from 123 to 237 horsepower. Expect far fewer options when the Tiguan eventually arrives on these shores. Both front-wheel drive and 4Motion are available, too. In addition to having standard, 4Motion, and R-Line variants on display in Frankfurt, VW also has the Tiguan GTE plug-in hybrid concept at the show. It combines a 1.4-liter TSI engine and an electric motor mounted to the six-speed DSG to offer a total system output of 215 hp. The 13 kWh lithium-ion battery also lets the PHEV cover 31 miles on electric power and get an estimated 124 miles per gallon on the European cycle. That's not too bad, but the roof also features solar cells that VW claims can add another 621 miles of driving range per year under ideal conditions.

Volkswagen reveals Golf GTI Clubsport concept at Worthersee

The various brands under the Volkswagen Group umbrella are bringing a slew of hot hatch concepts to the GTI-Treffen in Worthersee, Austria, this week – but the gathering wouldn't be complete without a version of the headline Volkswagen Golf GTI. And here it is. Previewed with initial details and a trio of design sketches last week, VW has now released a proper array of images showing the GTI Clubsport concept. The enhanced GTI packs an upgraded version of the stock version's 2.0-liter turbo four with 261 horsepower on tap, favorably splitting the difference between the standard GTI with the Performance package and the more potent Golf R. An overboost function even kicks in an extra 10-percent more horsepower to bring peak output up to 287 hp – just a few horses shy of the R's 292, but driving only the front wheels. As you can see, the Clubsport concept also features a more aggressive aero kit as well as upgraded rolling stock with semi-slick rubber. Most, if not all, of these enhancements are earmarked to find their way onto a 40th anniversary edition GTI, but we're unlikely to see that model in US showrooms. World premiere of the Golf GTI Clubsport at Lake Worthersee - Exclusive anniversary model for 40th birthday of the GTI - Golf GTI Clubsport debuts with 265 PS and boost function Next year, the Golf GTI celebrates its 40th birthday. Volkswagen is marking this historic event with a progressive anniversary model: the new Golf GTI Clubsport. Volkswagen will be showcasing the Golf GTI Clubsport on 14th May as part of the legendary GTI meet at Lake Worthersee, when it will make its world premiere in the form of a near-production concept car. With a power output of 195 kW / 265 PS (35 PS more than the Golf GTI Performance) and top performance temporarily increased by around a further 10 per cent thanks to a boost function, the Golf GTI Clubsport is set to take off at the start of 2016 as the most powerful production 'GTI' yet. The anniversary model is being launched not only with an extremely powerful engine, but also with an individualised interior and exclusive bodywork details. The design modifications include a completely new front bumper, new side sills, a new and aerodynamically highly innovative roof-edge spoiler and a specially developed rear diffuser. All of these features were designed with the aim of further enhancing the GTI's performance and of thereby bringing form and function into perfect harmony.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
