encore pire que ce que je pensais, vraiment inutileSaintor wrote:Selon l'EPA sur 25000km, il y a 150$ de différence entre une 528i N52 et 528 N20. Rajoutes +40% pour le marché canadien.....ça fait 210$.
Il aurait suffit de l'injection directe sur le 6 pour avoir ces mêmes résultats...
The Corporate Average Fuel Economy (CAFE) are regulations in the United States, first enacted by the U.S. Congress in 1975, and intended to improve the average fuel economy of cars and light trucks (trucks, vans and sport utility vehicles) sold in the US in the wake of the 1973 Arab Oil Embargo. Historically, it is the sales-weighted harmonic mean fuel economy, expressed in miles per US gallon (mpg), of a manufacturer's fleet of current model year passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 pounds (3,856 kg) or less, manufactured for sale in the US. If the average fuel economy of a manufacturer's annual fleet of vehicle production falls below the defined standard, the manufacturer must pay a penalty, currently $5.50 USD per 0.1 mpg under the standard, multiplied by the manufacturer's total production for the U.S. domestic market. In addition, a Gas Guzzler Tax is levied on individual passenger car models (but not trucks, vans, minivans, or SUVs) that get less than 22.5 miles per US gallon (10.5 l/100 km).
Starting in 2011 the CAFE standards are newly expressed as mathematical functions depending on vehicle "footprint", a measure of vehicle size determined by multiplying the vehicle’s wheelbase by its average track width. CAFE footprint requirements are set up such that a vehicle with a bigger footprint has a lower fuel economy requirement than a vehicle with a smaller footprint. For example, the 2012 Honda Fit with a footprint of 40 sq ft (3.7 m2) must achieve fuel economy (as measured for CAFE) of 36 miles per US gallon (6.5 l/100 km), equivalent to a published fuel economy of 27 miles per US gallon (8.7 l/100 km), while a Ford F-150 with its footprint of 65–75 sq ft (6.0–7.0 m2) must achieve CAFE fuel economy of 22 miles per US gallon (11 l/100 km), i.e., 17 miles per US gallon (14 l/100 km) published.
CAFE has separate standards for "passenger cars" and "light trucks", despite the majority of "light trucks" actually being used as passenger cars. The market share of "light trucks" grew steadily from 9.7% in 1979 to 47% in 2001 and remained in 50% numbers up to 2011. More than 500,000 vehicles in the 1999 model year exceeded the 8,500 lb (3,900 kg) GVWR cutoff and were thus omitted from CAFE calculations.

nah... selon fuel economy, la 528 2013 est à 24/34 alors que la 528xi est à 22/33...Saintor wrote:Imprez wrote:Pour se plier aux normes CAFE voilà tout.
Pffff. Pour ton information, l'EPA a forcé BMW à réduire leurs cotes déclarées. Maintenant une 328i 4-cyl. 240HP Step et une 335i 6-cyl. 300HP Step ont toutes deux les mêmes cotes.
Aussi BMW a réduit les cotes de la 528i. De 23/34, il a été rétrogradé à 22/32 (le même qu'une 528i 6-cyl. 240HP 2011) ET IL EST MAINTENANT À 20/30, pire qu'avec le 6-cyl.!!!!!

N20 = BIG JOKE.
