Just wondering with all the talk about the environment and reducing pollution and whatever why do people seem to think that 30mpg (7.84l/100km) is good? I don't understand why people think that they need 6 and 8 cylinders engines for driving around in the city... a 4 cylinder engine is more than enough for the usual city and highway driving... American cars websites are like "30mpg ... our biggest achievement since sliced bread". And then the other car manufacturers have to follow... Example: Volkswagen Golf engines start at 5 cylinder, 2500cc, 170 hp gas engine with 30mpg... lol. In Europe, they start at a 1.4, 80hp gas engine with 47mpg(5.1l/100km). The diesel version starts at a 1.6, 90hp engine with 62mpg(3.8l/100km). In Europe, Ford have a Fiesta with a 1.6, 90hp engine with 64mpg(3.7l/100km). I can't find it in the American website... Peugeot has a 1.6 diesel engine with 90hp and 72mpg(3.3l/100km). I guess Americans don't care about this because all i see is high powered gas guzzling cars that consume more while idling then a 1.2 in the highway. The air must be nice there and the gas must be cheap. Edit: Used US MPG.
