F1 - 1.6, 4 cylinders in 2013

Formula One takes another hit in the name of efficiency, both of cost and fuel, announcing today that the 2013 season will see the abandonment of the 2.4-liter V8 in favor of direct-injection (up to 500 bar or 7,252 psi) 1.6-liter four-cylinder engines. Additional "energy recovery systems and additional energy management" to ensure that the power remains similar to today's F1 cars.

Additionally, manufacturers will have their total number of engines per season reduced. Currently a driver can use eight engines per season. That number will drop to 5 in 2013 and then 4 after that.

The measures are said to increase fuel efficiency by 35%.

No biggie... it's back to the 80's turbo era. Hell... I think turbo engines are preferable... as they'll give manufacturers more flexibility in engine tuning... the difference between "power" and "economy" modes should be even more pronounced with these regulations.

1.6L turbo? honda, toyota, and bmw ought to return to F1 then!  :banana:

huh? are you sure its turbo?  I think its only n.a.  I read its only 12,000rm redline so if its non-turbo, no way can it approach the 700hp+ of the 2010 engines.

I think only 400hp lang yan pag non-turbo.  The old F1 turbo engines with 1500cc were putting out 1000hp+ before.  Still to get 400 hp from 1.6L turning only 12,000rpm is something I don't think exists today.

500 bar gas engine? That's sounds a lot, more than what is being used now.  Porsche GDI engine uses only 120-bar.  Diesel engines use up to 2000 bar so no big deal there, but F1 gas is a lot more flammable than diesel.  I hate to be in a crash when your 500-bar fuel line ruptures.  I think the 500-bar GDI systems is really for "green" purposes - low emissions and fuel efficiency.  But in terms of producing more power?  It's not a whole lot different imo.  A high pressure fuel direct-injection system makes more power cuz it can use higher compression without knocking compared to standard EFI systems.  (Still, I prefer the old EFI systems cuz they are tuneable, cheaper and reliable than, say GDI or gas direct injection system.)

I doubt of the 2013 cars will be as fast as the 2010 cars.  The 2002 cars were faster than 2010 cars so why should they be?

It's definitely turbo. They'll need it to approach current power levels.

The 2010 cars aren't as quick as the quickest F1 cars... but there are more severe limitations on aero-grip and power than there were before... with forced-induction, I expect the 2013 cars to be at least a match for the V10s in terms of outright acceleration... though the new aero rules should make them even slower in the corners.

yup sir, definitely turbo for f1 in 2013, i saw the article in autosport.com well it's good start for the sport though since it's greener, not sure for the specific horsepower though...

the quickest F1 cars are from the 1980's turbo era, while the most advanced as the Williams FW14 in 1992. (it had a semi automatic gearbox, active suspension, traction control and for a brief period anti-lock brakes.)

I hope these new 1.6 turbo engines still provide a spectacle for us race fans.

Most powerful, definitely... but the track records are still held by the V10s. Those cars had 900+ horsepower, as well... not as much corner-exit torque as the turbo cars, but they had better aero and tires. It'll take a whole lot of development in this aero-restricted age for the 2013 cars to match the V10s.

it's definitely turbocharged plus an additional 120bhp (i think) from KERS.
