Remarkably, SUVs were slightly less affected than large sedans: Sales of SUVs producing more than 200 g/km of CO 2 were down by 37.4 percent, compared to 53.7 percent for passenger cars in the same emissions category. As a result, the average car sold in Spain now produces 4.6 percent less CO 2 than last year, at 150.7 g/km of CO 2. This translates to slightly less power per average car, 118.5 HP (down by 0.75 percent) but also better mileage: 17.5 km per liter (about 42 mpg U.S. - EU highway cycle), which is 2.8 percent better than last year.
Spain's Registration Tax (also called "Inmatriculation") might be the reason. This tax is paid when purchasing a new vehicle. It changed on January 1st and became dependent on CO 2 emission levels, encouraging cleaner vehicle purchases. The new rate is zero percent for cars producing less than 120 g/km, 4.75 percent for cars between 121 and 160 g/km, 9.75 percent between 161 and 200 g/km and 14.75 percent if the vehicle produces more than 201 g/km of CO 2
