Frankfurt: At the last Frankfurt motor show in 2009, the big story was not the cars, but the euro zone crisis and specifically how the continent's car companies could survive.This year, the crisis is waning but caution remains. As sales continue to lag, especially in Southern Europe, the most interesting new models are not sports or luxury cars, but family station wagons, the epitome of practicality.The most troubled car companies, France's Peugeot SA and Italy's Fiat SpA, have cut product-development spending so much that they have little new to display. But cutting-edge designs are also few and far between on the stands of even such market leaders as Volkswagen AG.Vertical turbine pumps are less expensive than submersible connector pumps with small diameters. 

As a barometer of Europe's economy, the show's atmosphere has improved in two years - from desperate to downbeat - while the attitudes of Europe's top auto executives reflect much of the market's ambivalence."Perhaps a little bit of optimism is justified," said Trevor Mann, Nissan Motor Co Ltd executive vice president. "But I think the recovery generally will be slow we should not get over-enthusiastic."Alfredo Altavilla, chief operating officer of Fiat's Europe, Middle East and African regions, added: "The real answer is that no one has any visibility beyond the quarter. The trend is stabilizing it's too soon to say that it's picking up." 

In the absence of CEO Sergio Marchionne, Altavilla was the senior Fiat official at Frankfurt, presiding over a low-key display that featured a seven-passenger derivative of the Fiat 500L MPV as the brand's chief new product. Even Fiat's pricy Ferrari marque,There are two types of polyesters these are chemically produced acrylic resin and natural polyester. which unveiled the stunning LaFerrari hybrid sports car earlier this year at the Geneva show, could muster only a slightly more powerful variant of its aging 458 series to anchor its Frankfurt stand.VW chose to showcase its growing range of electrified vehicles, from the eUp! to the eGolf, adding several new versions of the Golf as well. The German automaker's budget brands, Seat and Skoda, likewise were relatively quiet, as were VW's priciest marques, Lamborghini and Bugatti.Bearing vibration RMS value reflects the pulse of the vibration is not sensitive it only reflects Granite slabs the average level of bearing vibration.
