Formula 1 2017 vs 2018: What’s changed?

Formula 1 2017 vs 2018 Whats changed

Break out the microscope, as F1 teams meld carbon-fibre in intricate detail to eke out any advantage possible

THE 2018 F1 regulations remain largely unchanged from 2017, save for the newly mandated halo safety device.

Last year’s championship was the first season of all-new regulations which transformed F1 cars into wider, longer beasts. The end result was every current Grand Prix circuit bar one having its lap record smashed (Monza’s record remains intact thanks to a sodden qualifying session).

Despite the rulebook remaining largely unchanged, it’s still worth looking at the 2017 and 2018 F1 challengers side by side to look at how the teams have developed their current designs to make cars even faster.

To illustrate this, let’s compare Ferrari’s 2017 SF70H and 2018 SF71H F1.

The clearest visual changes are the removal of the shark fin and T-Wing, and addition of the halo safety device over the cockpit. Ferrari has fitted the halo with a more aerodynamic fairing as allowed in the rules, featuring a curved winglet to help direct air over the top of the car away from the roll hoop structure.

Exhaust-blown monkey-seat devices have been outlawed for 2017, however Ferrari has continued to develop aerodynamics at the far rear of the car, introducing a T-Wing-esque device which sits atop the exhaust, but behind the rear wing mounts.

Maranello’s engineers have worked heavily on the sidepod and forward barge board design, with that section of the car expected to be subject to intense development this year.

The SF70H’s sidepods were unique when they debuted last year, with very high, narrow inlets, and intricate packaging within. This has been further developed, with the intakes split, and now even smaller than 2017.

Even the wing mirrors aren’t safe from being transformed into an aerodynamic device in F1, with the SF71H sporting wind-tunnel designed mirror housings.

At the nose of the car, the front wing mount has followed a design similar to what McLaren pioneered with a number of air vents integrated into the mounting.

There’s also been a shift in design philosophy around the car’s wheelbase, with the SF71H’s being stretched in length akin to that seen on the Mercedes-Benz W09 last year (which won both the drivers’ and constructors’ championship).

Pre-season testing begins this week in Spain, and you can be sure each F1 team will be trying to sneak a peek at each other’s creations ahead of the first Grand Prix, in Melbourne on March 25.
