"McLaren finished last year with the fastest car and the new MP4-28 looks like a good improvement on that.

"The steps forward start at the front with a higher nose and chassis, pretty close to the maximum allowed height, which gives more room for better airflow under the car than last year.

"They have followed Ferrari's 2012 lead in using pull-rod front suspension, which has a lower centre of gravity and the pull-rod manages the airflow off the front wing better than the more common push-rod.

"The sidepods have been moved backwards, giving better airflow, and the back has been focused on maximising that flow.

"The driveshaft and lower wishbone have been packaged in one element and the rear bodywork is heavily scooped out to make the most of the downforce-producing 'coke-bottle' area between the rear wheels.

"The idea is to separate that airflow from the exhaust gases, which McLaren have continued to treat in the way they did last year, rather than using Red Bull-style tunnels.

"McLaren are one of the few teams to have small-diameter exhaust exits, which gives faster airflow and therefore more downforce when they hit the aerodynamically shaped rear brake ducts.

"Overall, McLaren look to have made a good step forward."

I don't know why people get so excited about launches.

So the nose fitted to the new car isn't a stepped nose then.

Yes it is, but the cover is neatly integrated, and only disstinguishable from the stepped nose in unpainted condition.
