So, now that I completed my garage and can finally win this game of "who has the slowest diesel", I might aswell join
The joker first:
1979 Mercedes-Benz O309 508D 'Blume'
3758 cc, Diesel I4, N/A, manual
63 kW @ 2800 rpm
235 Nm @ 1800 rpm
3460 kg "leergewicht" (probably inlcuding the original police equipment, no idea how much it is now)
98 km/h max speed
0-100: probably infinty, then
The other two are almost equal in kW/to, so here goes the light cruiser:
1980 Mercedes-Benz W116 280S
2717cc, gas, I6, N/A, automatic
115kW @ 5500 rpm
222,6 Nm @ 4000 rpm
1610 kg leergewicht
185 km/h top speed
12.5s 0-100 km/h (atleast according to wikipedia)
14,6 l/100km according to my signature
and last but not least my equivalent to an mx-5, since I cant properly fit in an actual mx-5:
1990 Mercedes-Benz W124 230E
2298 cc, gas, I4, N/A, manual
97 kW @ 5100 rpm
198 Nm @ 3500 rpm
1330 kg leergewicht
210 km/h top speed (according to my GPS, four years ago)
0-100: 11,3 s
8,4 l/100km (steadily getting better now

)
