Consumption and start speed b.Jimny

Hello,I wanted to hear what your Jimny`s need so much fuel?My wife’s not exactly sparing ,will say ,the soaks like a hole .Have now done a test drive with approx.100-110Km/h and come on almost exactly 10l at 100Km.At highway directional speed the consumption is incredible 13l.For a 1.3 engine with 86hp and the original “circular saws” tyres a proud value! Furthermore, when starting in cold condition he immediately turns with approx.2000U/min (I last had with my old F Ord with carburetor, but the injections I have driven up to now, had a maximum of 300-400 rpm more when starting.Is this normal with Suzuki?Isn’t it really engine-friendly, if you have to torture the cold, not oiled engine already so. Please for your active help,bin Suzuki Jimny Neulimg!!! MfG Michael PS:Ach,the car is now 6months old and has 7000 km on the speedo.Is a convertible(because of the fuel consumption)
