If you haven’t heard already, F1 is set to ban the hydraulic heave springs that many teams (notably Mercedes) have been playing with over the past 12-15 months. Although it is not an official ban as yet, a technical directive has been issued to the teams addressing the claims that Ferrari raised in a recent letter to the FIA. Ferrari claims that the component can be classed under the ‘moveable aerodynamics’ catch-all phrase in the regulations, and although it has been discussed in great length over the year it is only now that the Scuderia have chosen to make a formal move against the competition. In this blog post we will aim to cover what the hydraulic heave element does and why a ban at this stage of the 2017 developments could have an impact on the pecking order. Continue reading
One of the key design features of this year’s Mercedes W07 is the introduction of an S-duct. The S-duct was first seen in 2012, with Sauber using it as a way to manage airflow over the stepped nose. The idea was that airflow would be less likely to detach from the chassis if air was introduced behind the step. This was done by channeling airflow from underneath the car to a vent exiting backwards above the front bulkhead via an s-shaped duct in the nosebox, hence the term S-duct.
As you may (or may not) know, all of my technical analysis pieces for the 2016 F1 cars are up on F1 Fanatic this year. However I’ve made it really easy for you to find your favourite car/team by linking them all in this post! So here you are – enjoy!
- Mercedes W07 – Can the World Champions continue their winning streak?
- Ferrari SF16-H – Ferrari’s bold winter strategy could bring them a step closer to the Mercs
- Williams FW38 – The FW38 is arguably the most important car for Williams in a long time
- Red Bull RB12 – 2016 may be a stop-gap for the Bulls, but don’t discount them for a podium
- Force India VJM09 – Will Force India be able to keep pace with the bigger budget teams?
- Renault R.S.16 – It’s Renault’s first year back as a Constructor, so how will the R.S.16 fare?
- Toro Rosso STR11 – Arguably the boldest car on the grid, Toro Rosso mean business in 2016
- Sauber C35 – Sauber have their eyes on 2017, but the C35 is nonetheless a solid evolution
- McLaren MP4-31 – Time to step up, McLaren, and the new car shows it
- Manor Racing MRT05 – Now with Mercedes propulsion, can Manor fight for points?
- Haas VF-16 – Debutants Haas have gone down the listed parts strategy. And it could work!
Note: This post will be updated as the articles are released.

On the very first test outing of the current generation V6 turbo hybrid power units back in February 2014, photographers and journalists got their first taste of the sound of the future of F1. Needless to say, the paddock was split. They are far from the screaming naturally aspirated engines of the past but do arguably offer a much deeper and richer blend of tones, albeit at a substantially lower volume.
There have been complaints from a lot of fans about the lack of decibels over the past year and a half, which is why the FIA have decided to take action ahead of the 2016 season. This involves splitting the wastegate and engine exhaust gases into two separate systems.
At the moment, the exhaust gases from the engine (via the turbocharger) and from the wastegate system all exit through a single exit pipe at the back of the car. The single exhaust pipe layout allows the wastegate gases to escape the bodywork cleanly and prevent internal overheating although this does slightly hinder the overall volume of the exhaust tone.
For 2016 the FIA have decided to divide the ICE and wastegate gases into two sets of pipework, whereby the teams must retain the single, large exhaust exit for the former and up to two smaller outlets – straddling either side the central exit – for the latter. The motorsport governing body think that by splitting the two systems the engine sound will be louder than before, although it is actually more likely to change its tone. Regardless of whether it works or not, at least we won’t be seeing the ‘trumpet’ exhaust tested last year!
Another interesting topic that has emerged from the regulation change is whether it will have any aerodynamic benefits. We have witnessed the power of exhaust gases when it comes to generating downforce when Red Bull pioneered the EBD (exhaust blown diffuser), but will we something similar next year? Continue reading
Pretty self explanatory – I’ve decided to branch out to YouTube! For now I’ll be based in the ‘studio’ that is my parents’ study, but I’ll set up something different when I’m back at university in Swansea next month.

As Le Mans 2015 kicks off today, a new competitor in the LMP1 category is making its debut – Nissan have entered the fiery pit that has belonged to Audi for many years. With Porsche coming in last year and Toyota sparking a resurgence against the dominant four rings, endurance racing has never been more popular in its entire history towards the front end of the grid.
Nissan’s challenger – the GT-R LM NISMO – is nothing short of the word different. It completely turns the philosophy of the modern high end endurance racer on its head, but Nissan are confident that in the future this will be a competitive design.
How is it different to the others?
The GT-R LM NISMO’s engine is a longitudinal front mounted 3 litre twin turbo V6, its power delivered to the front wheels via a 5-speed Xtrac sequential gearbox. The car also incorporates an epicyclic gear cluster to finetune final drive, much like you would find in an automatic transmission. Considering that there is a new fuel flow limit for this year’s World Endurance Championship, its power output of 500hp is pretty good.
As per the regulations, the Nissan is also equipped with hybrid technology in the form of two Torotrak flywheel energy stores, linked to a pair of motor generator units (MGUs – see more on these here) on each front wheel. These have an additional 750hp available so the total potential power output is a staggering 1,250hp.
The flywheel energy stores are also capable of sending energy to the rear wheels via two MGUs located inside each rear hub, which at times can make the Nissan an all-wheel-drive weapon. However it is unlikely they will run energy rearwards for this weekend as they have encountered some reliability issues in recent testing.
All of the car’s radiators are packaged tightly around the powertrain.
The front tyres are also larger than the rears at 360mm and 230mm respectively. This allows greater traction at the front driven wheels whilst reducing friction and creating more space at the rear for the diffuser. More on this in a moment… Continue reading
