Renault Fluence metallic). It can accelerate from 0-100 km/h (62 mph) in 8 seconds and top speed is limited to . In 2004, Renault presented a 2+2 concept coupé, named Fluence and designed by then Renault chief designer Patrick le Quément, with a length similar to that of the Renault Laguna. It was shown on June 4, 2004, at the "Louis Vuitton Car Elegance Classic" in England, and at the Mondial de l'Automobile 2004. The Fluence uses Valeo LED headlights that are angled according to the steering wheel position. An ingenious aspect of the Fluence's exterior design is its V shaped rear
Latitude of the Gulf Stream and the Gulf Stream north wall index analysis was then used to find the pattern of variation common to the six longitudes. This is preferable to simple averaging of the six latitude estimates which would emphasise the eastern longitudes where the north-south movements are largest, and possibly obscure smaller but coherent north-south shifts further west. Correlation coefficients are calculated between the six time-series and the principal components are the eigenvectors of the resulting correlation matrix. (Empirical orthogonal function analysis proceeds instead from the variance-covariance matrix which again is biased to the eastern longitudes.) Each principal component is calculated as a weighted average of the standardised latitude series
