4 or 6 cylinder turbocharged engine. Drop the refuelling and set a maximum tank size.
If the manufacturers want to look 'green' that would be a good start. Leave the engine capacity open, design considerations will put a cap on that pretty quickly.
They're not going to sound amazing but if you want a design challenge with green credentials and marketability for road cars, that's the way to go.
Just PLEASE don't go to diesel.
Oh, and allow CVTs while they're at it. They'll sound rubbish but again, design challenge, green credentials and (hopefully) marketability if the technology transfers across.
Some interesting ideas out there, one can only hope Max and Bernie see them.
I can't agree with some of ESP's ideas though,
Limit each driver to 5 engines a season, bomus points for relyability given before last GP of the year; 1 engine for the year gets 10 points down to no points for 5 engines. Each driver will be alloted a specific Test engine outside race allocation
6 engines in total and writing off engines that might just need a crank seal replacing? Also, surely the reward for reliability is finishing the race.
Each eingine will have a aloted gearbox as well Sealed by FIA at start of season, no changins any part for "relyability puroposes"
Allotted gearboxes, what if there is a shunt which damages it. Would there be a penalty for changing it? Anyway, there is a current regulation on the number of races a 'box must do which achieves this to some extent
Allow the driver to only make a engine map change every 120 seconds, thus engine management for the driver will be lessened, meaning more time for him to think on passing the car in front
There are several 'engine maps' which the driver can change not just one, those aren't changed frequently anyway, maybe dozen times per race in total. So, the diver is hardly taxed.
Standardise engine management software and have telemetry open and free to all, realtime, allow other teams to watch other teams telemetry
Telemetry open and free to all, no thanks. Everyone then needs 20+ DST systems (or the FIA providing feeds to everyone) plus engineers watching the data. Anyway, from a practical point of view the data doesn't mean much without knowing the cars set up, more useful would be info about fuel loads. This could be achieved much more easily by banning encrypted radio systems in the pitlane
BTW the software is already standardised and has been since '08
tunring off cylinders and being able for the car to run on 2 cylinders behing the Saftey Car or being able to have the car as a V6 for say 5 laps to save 2 laps of fuel when behind a slower car.
The cars already have 4 cylinder modes which can be used under idle and safety car conditions. The fuelling map can also be changed by the driver to reduce fuel consumption when in traffic or at the end of a race
Fuel tanks will be limites to 40 litres, meaning that most races will see at least 3 stops Standard unleaded fuel that is readily avalable at the consumer pump must only be used, no speciality race fuel
I can see your argument for standard fuel though and it would be easier if the FIA just supplied everyone with the same stuff for each race. Comparison would be easier as well as you would just keep a sample from the batch. The only downside is that Shell, Total etc wouldn't be so keen on supporting F1 if fuels were standardised.
Current race fuel is not dissimilar to what could be bought as pump fuel. Do you know what happens to the leftovers when the fuel batch is changed? They get burnt via road going combustion engine, so it can't be that different
However, unless great steps are made in F1 fuel economy a 40L tank would mean more than 3 stops, more like 5 for a typical race.
The FIA did have similar ideas on a few things though ESP (software, 4 cyl idle, sealed gearboxes) but a few are, I think, impractical.
