It's been 21 years since a turbocharger found its way onto a Formula One racer. In 1989, the FIA banned forced-induction due to the ridiculous power and speed they were generating. For better or worse, things haven't been the same since, but if a report from Pitpass is to be believed, we may see the reign of the turbo return once again.

The site is claiming that the FIA is seriously considering bringing a new turbocharged 1.5-liter engine to F1, but don't expect to see early '80s power from these machines. The four-cylinder engine is being considered for one reason alone – to reduce fuel consumption and emissions.

So we won't see over 1,000 horsepower from the 2011 grid, but to make up for the dip in grunt, Pitpass says the FIA is also considering allowing KERS to return. While we're sure the sanctioning body is keen to get the eco-minded off its back, odds are the FIA wouldn't mind spicing up the racing a bit, either. While we were promised heart-stopping action from the 2010 season, so far the racing has been much of the same. Here's hoping...

      Now that would be the sweetest thing the FIA could do, the last couple where at best mediocore, No refueling (lame but has some promise when it rains). But a boosted motor (with temporary overboost periods would be awesome) Kers would add even more of a speactacle think about hitting overboost and Kers on a straight to pass! Also it will be awesome just to see how much power the can put out on a turbo 1.5 4 banger and how much of that tech can be brought into road going vehicles!

      I would love to see different engine types in formula one. I just wish aerodynamics could be limited more per race. I also wish for more safety in the pits. I know not all teams pit at the same time but I want more strategy coming into play with the racing. There is to many people in the pits just to change the tires this season. Maybe, limiting the pit crew more could save some money for the smaller teams. Maybe, do something similar to that of NASCAR, however no jack guy, keep that the way it is. Bring back refuelling with a standard size say 100 litre tank or smaller. They could do this where refuelling can only happen with the engine off and with four tires on the ground. I know this can make the pit longer so careful strategy is always going to win. Allow for auto adjusting suspension because it could make the car safer, however, say after the second Friday practice they cannot adjust the suspension any more. This could possibly provide interesting ideas if teams do not setup the suspension for rain conditions, however I know it is unlikely to happen. However, it seems to me that the fun that F1 use to have is all gone I really have lost my interest in recent years. Been more into WRC and SuperGT.

      I see no reason why those 1.5 liter engines can't be V12s or V8s. Ferrari's first ever engine was a 1.5 liter V12.

      Hell, I'll go one further and ask why they don't put engines like that in passenger cars. Would make them sound a lot better and with MDS would be a lot more fuel efficient than four bangers of the same displacement.

        I would guess under that 'formula' you'd end up with
        600hp+ 1.0 inline 5 turbo 80mm bore x 39.78mm stroke
        600hp+ 2.0 V10 80x39.78 (22,000+rpm sounds nice!)

        More cylinders means more friction, which makes the engines less efficient. And the engines would cost more. I don't think there's a future for tiny cylinders in cars.
        • 4 Years Ago
        About F1's with 1.5 liter V12s: Anything goes with a racecar. Personally, I think they should keep the V8, V10 or V12 sound. Wouldn't be the same without it.

        About street cars with smaller V8's: I agree that 1.5 liters for a V8 would be a bit small. However, a 2.8 liter V8 would be the perfect size. You'd have the sound of an old F1 car, it would become a 1.4 inline four in economy mode, and it would fit in virtually any car.

        Hell there used to be 1.5 liter 16 cylinders engines.

        F1 should just say, 2 liters, naturally aspirated no limitations as to bore, number of spark plugs, maximum revs.
        1 liter turbocharged to high heaven.

      Yes. Turbo 1.5L cross-plane inline four. Flat-plane inline fours sound pox IMHO. Odd firing intervals have benefits (cross-plane cranks have benefits) but the sound is also rich in other detail that is lacking from even firing intervals.
        • 4 Years Ago
        Yes it would make a virtual V4. The bonus is you only have one of each camshaft etc - so fewer frictional losses. Motorcycle V4 engines seek to reduce width and gyroscopic effect through length (width) of crank. V4 engines can also save friction through fewer bigend bearings (two conrods on a single journal) but this is minimal. Since cars don't need to worry about gyroscopic effect so much, an inline is fine.

        Boxers are awesome because they allow a low CofG but to my knowledge they are 180 degree firing interval just like a traditional inline four. The only reason they sound different is because the exhausts are paired that way. Someone else may correct me.

        My old Gemini (with Isuzu G200 like the 1.8L in Chev Luv ute) sounded great but that's coz of the extractors and the decent sized main exhaust. It was still an inline four in sound though.

        I love triples and sixes.
        • 4 Years Ago
        Would that essentially be make it a v4, then?

        I can't think of an inline-4 that sounds good myself, other than my OHC 2.2 Cavalier which was a piece of junk anyway.

        All i know is that Subaru's boxer 4's sound friggin' amazing.

      IMHO, Turbocharged 1.5 liter engines belong about 3 feet infront of wannabe max power columnists. The ridiculously high revving 2.4l V8's keep some of the sheer lunacy you need to keep these sports interesting. Lets not forget how much these sports pour in to the economy (not my fault for getting all political about it), that alone should get the eco club off Bernie's back.

      If you've ever seen the BMW F1 engine in person (BMW Zentrum in Spartanburg, SC) from the Mid 70's you have to be impressed. I could just about fit it in the trunk of my current car (sedan). It was an inline 4 cylinder turbo that pumped out over 1300hp. The engineers said they think it was close to 1500 but the dyno topped out at 1300 so they went with that figure.

      I like this idea, hopefully they don't specify a cylinder count. I would love to see a 1.5 V12.
      • 4 Years Ago
      No matter what they do, I wish they'd allow more configurations of engine, NA V12 vs. Turbo I4 vs. huge V8 vs. mega-KERS V6 or whatever. If they want limits, require a production block...that'd keep costs down but insanity up. A little bit of me dies each time an F1 engine is limited to ONLY 18K rpms. The Renault and BMW V10s were pushing 19.8K when they started limiting them.

      And KERS sucked because, once again, they limited it to only scavenging a small amount of energy, not all they could.

      Aaahhh... Limits!

      oh, too bad. I wouldn't mind the 1650HP Inline 4 cylinder Turbo BMW engines making a comeback.
