Porsche-Diesel L 308 or Renault Super 7 (R 7055)?
Which should you choose?
The data can’t decide this. Power at the PTO shaft cannot be compared: the L 308 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 7 (R 7055) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- The Renault Super 7 (R 7055) suits road haulage better on this data: 25% (5.0 km/h / 3.1 mph) more top speed.
Generated by rule set compare@4 from the figures on the side-by-side table, allowed by route “the same stated configuration”. Measured figures are compared only with measured, claimed only with claimed, at the same test condition; differences within each figure’s tolerance are not called.

What does this mean in plain words?
- The Renault Super 7 (R 7055) has 25% more top speed (5.0 km/h / 3.1 mph) than the Porsche-Diesel L 308 (both top speed forward, as stated by the source).
- Even on weight (both unladen weight, as stated by the source): the difference is under the 10% threshold, too small to call.
- Even on forward gears (both forward gears, as stated by the source): the difference is under the 25% threshold, too small to call.
- Even on PTO speeds: the same speeds (540 rpm).
- Even on drive: all two-wheel drive.
- Same era: production began within 5 years of each other. We hold no parts-availability data, so there is no call on parts.
- Not comparable on power at the PTO shaft: the L 308 has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft; the Super 7 (R 7055) has only engine power (gross or net not stated), claimed — a different quantity from power at the shaft.
- Not comparable on three-point lift: the L 308: lift at an unstated point, as stated by the source (Traktorenlexikon, “Porsche-Diesel Super L308”); the Super 7 (R 7055): lift at the hitch ends, as stated by the source (Traktorenlexikon, “Renault Super 7 (R 7055)”) — not the same quantity, basis and condition.
- No figure on record for every machine, so no call on: fuel efficiency at the shaft, drawbar power, hydraulic flow, maximum permissible mass, a creeper range and PTO independence.
