Alonso only McLaren driver to get new-spec Honda engine

Fernando Alonso will have exclusive use of Honda's updated engine at the United States Grand Prix, with Jenson Button sticking to the old specification for now.

The new Specification 4 engine, believed to deliver around a 20bhp boost in power, was tested by Alonso during Friday practice at the Russian Grand Prix.

With McLaren encouraged by early feedback, and Honda's post-race analysis confirming it was happy with the updates, it has given the green light to it being raced by Alonso in Austin.

However, with a long lead time to manufacture new specification parts, Button will have to wait a little longer to get his hands on the engine.

Once Honda has built the new engine, then Button is expected to race it – even though it will mean a grid penalty.

For now Button will stick to the Specification 3 power unit that was introduced at the Italian Grand Prix.
