What lands on the bench

Jump leads 4.5 m (15 ft) long with 35 mm (1.38 in)² copper-coated aluminum conductors, stated for petrol engines to 7000 cc and diesels to 4000 cc.

Why these two numbers belong together

Length adds resistance; section removes it. A long thin lead is worse than a short thin one, and a long thick lead is the only combination that is both reachable and capable. This pair is the best-balanced here.

What the engine ratings tell you

That a 4 liter diesel is within the design intent. That covers vans, large estates and pick-ups, which is where cheaper leads run out.

The one thing missing

A storage bag. Worth improvising, because loose clamps in a boot damage their own insulation.

The questions that reach us

Is 35 mm (1.38 in)² overkill for a small car?

It costs a little more and weighs a little more, and it will never be the limiting factor. Leads are bought once for a decade, and the larger section is what makes them work on the day they meet a cold diesel.

Does length reduce performance?

Slightly — longer cable means more resistance. That is precisely why longer leads use a larger section, and why comparing length without section is meaningless.
