This is the McLaren-Honda MP4-30

After 23 years, the band is back together. McLaren has today unveiled its 2015 F1 car, dubbed the MP4-30 and, for the first time since 1992, packing Honda power.

After a six-year absence from F1, Honda is returning to the grid this year as an engine manufacturer to the Woking outfit.

The McLaren-Honda relationship is one of the most illustrious in F1 history. Between 1988 and 1992, Honda-powered McLarens won eight world championships and 44 grands prix, taking 53 pole position and 30 fastest laps in just 80 grands prix.

1988's McLaren-Honda MP4/4 was possibly the most successful F1 car in history, winning 15 of that season's 16 races in the hands of some blokes called Ayrton Senna and Alain Prost.

No pressure on McLaren's 2015 driver line-up of Jenson Button and Fernando Alonso, then. Though after 2014's annus horribilis, in which McLaren finished a dismal fifth in the constructor's championship, this year could hardly go a whole lot worse.

And the MP4-30 looks a tidy enough thing, with a low, flat nose mercifully free of the proboscis appendages of many of last year's F1 racers. We're told the hand of chief engineer Peter Prodomou, who joined McLaren from Red Bull last year, features heavy in the design.

Can Honda's turbo V6 hybrid power unit possibly propel McLaren to the front of the grid alongside, presumably, Lewis Hamilton's Mercedes? It's one hell of an ask for a new engine manufacturer to hit the ground running, especially with a powerplant as phenomenally complex as the ERS-enabled 2015 units.

But don't forget the finest hours of McLaren-Honda glory years came courtesy of a turbocharged V6. Reckon the MP4-30 could see Jenson and Fernando getting wheel to wheel with Lewis and Nico?
