Size It Up Vehicles answer: September 13

The five Vehicles silhouettes for September 13, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 10 ran from a kayak (3 m) to an Ariane 5 ECA (53 m). The widest gap was round 2, Kayak against Flying Scotsman, at 7.1×; the closest call was round 4, Ariane 5 ECA against C-17 Globemaster III, only 1.0× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Fire Engine (pumper) vs Bugatti Chiron

    Bugatti Chiron · reference · 4.544 m
    Fire Engine · true length · 10 m

    2.2× longer than the Bugatti Chiron

    A pumper fire engine is about 10 m long — shorter than a city bus, and it still needs the whole street to turn.

  2. ROUND 2

    Kayak (recreational) vs Flying Scotsman (engine + tender)

    Flying Scotsman · reference · 21.4 m
    Kayak · true length · 3 m

    7.1× shorter than the Flying Scotsman

    A recreational kayak is about 3 m long.

  3. ROUND 3

    Cat 797F Mining Truck vs Semi-Trailer Truck (tractor + 40 ft trailer)

    Semi-Trailer Truck · reference · 16.5 m
    Cat 797F Mining Truck · true length · 15.08 m

    1.1× shorter than the semi-trailer truck

    The Cat 797F is 15.08 m long. The dump body alone is shorter than the complete mining truck.

  4. ROUND 4

    Ariane 5 ECA vs C-17 Globemaster III

    C-17 Globemaster III · reference · 53 m
    Ariane 5 ECA · true height · 53 m

    1.0× taller than the C-17 Globemaster III

    Ariane 5 ECA reaches about 53 m in its tall configuration. Fairing choices change the total height.

  5. ROUND 5

    Spitfire Mk I vs John Deere 8R 410 (without front linkage)

    John Deere 8R 410 · reference · 6.065 m
    Spitfire Mk I · true length · 9.1 m

    1.5× longer than the John Deere 8R 410

    A Spitfire Mk I is about 9.1 m long. The propeller disc adds height to this side view, not length.
