what's the top speed of a f1 car
Formula One car For a decade, F1 cars had run with 3.0-litre naturally aspirated engines with all teams settling on a V10 layout by the end of the period; however, development had led to these engines producing between 980 and 1,000 hp (730 and 750 kW),[5] and the cars reaching top speeds of 375 km/h (233 mph) (Jacques Villeneuve with Sauber-Ferrari) on the Monza circuit.[citation needed] Teams started to use exotic alloys in the late 1990s, leading to the FIA banning the use of exotic materials in engine construction, with only aluminium, titanium and iron alloys being allowed for the pistons, cylinders, connecting rods and crankshafts.[4] The FIA has continually enforced material and design restrictions to limit power. Even with the restrictions, the V10s in the 2005 season were reputed to develop 980 hp (730 kW), power levels not seen since the ban on turbo-charged engines in 1989.[5]
Monster Energy NASCAR Cup Series The cars are powered by EFI V8 engines with compacted graphite iron blocks and pushrod valvetrains actuating two-valves per cylinder, and are limited to 358 cubic inches' (about 5.8 liters) displacement. However, modern technology has allowed power outputs near 900 horsepower (670 kW) in unrestricted form while retaining the conventional basic engine design. In fact, before NASCAR instituted the gear rule, Cup engines were capable of operating more than 10,000 rpm.[31] A NASCAR Cup Series engine with the maximum bore of 4.185 inches (106.3 millimeters) and stroke of 3.25 inches (82.55 millimeters) at 9,000 rpm has a mean piston speed of 80.44 fps (24.75 m/s). Contemporary Cup engines run 9,800 rpm, 87.59 fps (26.95 m/s), at the road course events on Pocono Pennsylvania's long front stretch and at the .526-mile short-track Martinsville Speedway. At the backbone 1.5- to 2.0-mile tri-oval tracks of NASCAR, the engines produce over 850 hp running 92–9400 rpm for 500 miles, 600 mi for the Coca-Cola 600 Charlotte race.
