* Drops in oil and euro buoy airline and automotive stocks
* Banks turn around after Wells Fargo results
By Patrizia Kokot
LONDON, July 16 (Reuters) - European shares ended higher on Wednesday as falling oil prices supported the broader market, a weaker euro underpinned automotive stocks and solid results from Wells Fargo <WFC.N> lifted battered banks.
The FTSEurofirst 300 <
> index of top European shares closed 0.5 percent higher at 1,115.97 points, having fallen as much as 1.6 percent earlier in the session.A $5 drop in crude <CLc1> on the back of a surprise increase in U.S. inventories lifted airline stocks, with Air France-KLM <AIRF.PA> rallying 7.8 percent, Lufthansa <LHAG.DE> up 4.8 percent and British Airways <BAY.L> up 6.9 percent.
Automotive stocks soared as the U.S. dollar strengthened against the euro <EUR=> after Federal Reserve Chairman Ben Bernanke told a U.S. House of Representatives panel that currency intervention may be warranted under certain conditions.
BMW <BMWG.DE> was up 2 percent, Renault <RENA.PA> rose 7.4 percent and Peugeot <PEUP.PA> added 4.6 percent.
BANKS STAGE SHARP TURNAROUND
Banks, the heaviest drag on the European market earlier in the day, ended higher after Wells Fargo reported unexpectedly strong quarterly results.
The DJStoxx European banks index <.SX7P> rose 1.6 percent, with Barclays <BARC.L> adding 2.4 percent and Fortis <FOR.BR> <FOR.AS> gaining 4.6 percent, and UBS <UBSN.VX> rising 3.4 percent.
Alpha Trading asset manager Stefan de Schutter doubted the longevity of the turnaround witnessed in late trade.
"We were oversold earlier and this is a technical rally. The comments from Bernanke were a big push but in the end nothing has really changed," he said.
Andreas Huerkamp, a strategist at Commerzbank in Frankfurt, said there are some signs that the current downtrend is coming to the end.
"Depressed investor sentiment was, contrary to our expectations, not able to stop the current correction of equity markets," he said, adding that a VDAX <.V1XI> of 26, as well as a put-call ratio of 1.10 are historic signals that the downward trend is losing momentum.
The VDAX-NEW volatility index, based on sell and buy options on Frankfurt's top 30 stocks, was down 3.7 percent at 26.76.
Huerkamp said that company earnings had shown a surprising resilience throughout the credit crunch, noting that "our economic-earnings-valuation-sentiment-model still indicates that the current dip should be the last dip in the current crisis".
Among companies reporting on Wednesday, Alstom <ALSO.PA> jumped 8.5 percent after the French high-speed train and industrial power plant group posted solid first-quarter sales.
OIL STOCKS HIT FTSE
Britain's commodity-heavy FTSE 100 <
> ended down 0.4 percent, while Germany's DAX < > added 1.2 percent and France's CAC < > rose 1.3 percent.Heavyweight oil groups BP <BP.L>, Total <TOTF.PA> and Shell <RDSa.L> shed between 2.8 and 3.2 percent.
Germany's Deutsche Postbank <DPBGn.DE> slumped 7.3 percent amid fears that a three-way merger with Commerzbank <CBKG.DE> and Allianz <ALVG.DE> could fail and leave the retail bank stranded without a buyer or partner in its quest to expand its operations. Other notable decliners included Norwegian fertiliser group Yara <YAR.OL>, down 7.2 percent amid worries over its outlook and concerns that consensus estimates may be too high, traders said.
