Summary

TLDRThe video compares a 1979 Toyota Land Cruiser 70 series with a 4-cylinder turbo diesel and a 1976 Land Cruiser 70 series with a V8 through various tests. It finds the 4-cylinder has better acceleration and hill climbing ability despite having fewer cylinders. However, the V8 sounds better and is more enjoyable to drive manually. After weighing them equally, the 4-cylinder decisively beats the V8 in a quarter mile drag race.

Takeaways

  • 😀 They compared a 4-cylinder turbo diesel 70 Series Land Cruiser to a V8 76 Series in multiple tests
  • 🚙 The 4-cylinder was faster in 0-100 km/h, towing, and hill climbs
  • ⛽️ But the V8 used less fuel at highway speeds without towing
  • 💨 The 4-cylinder has 500 Nm torque vs the V8's 430 Nm
  • 🚚 Towing performance was way better in the 4-cylinder due to the extra torque
  • 😢 The V8 struggled on steep hills and needed low gears constantly
  • 👀 The 4-cylinder blew the V8 away in real world towing tests
  • 🏎 The 4-cylinder narrowly won both standing and rolling drag races
  • 😭 But the V8 still sounds better and is more enjoyable to drive manually
  • 🚘 Emissions regulations will likely make V8 70 Series extinct soon

Q & A

  • What vehicles are being compared in the test?

    -A 1979 Toyota Land Cruiser 70 Series with a 4-cylinder turbocharged diesel engine and automatic transmission is being compared to a 1976 Toyota Land Cruiser 76 Series with a V8 engine and manual transmission.

  • What tests are conducted on the vehicles?

    -The vehicles are tested using a trailer dyno, taken on a simulated country road with hills and tight turns, and raced in quarter mile drag races from a standstill and a 50 km/hr rolling start.

  • How are the vehicles weighted equally for the tests?

    -Extra weight is added to the 79 Series to match the curb weight of the heavier 76 Series V8.

  • Which vehicle performed better in the trailer dyno tests?

    -The 79 Series 4-cylinder turbo diesel accelerated faster and climbed hills easier than the 76 Series V8 in the trailer dyno tests.

  • What issue did the V8 have driving on the hill road?

    -The V8 lacked low-end torque, needing to downshift on hills where the 4-cylinder could stay in a higher gear. The V8's narrow rear track also made it feel unstable on turns.
