Automobile Quiz! (Petrolheads and Grease Monkeys only Attempt)

[650lb Sumo]

(1) What are turbochargers and superchargers and how are they powered? (Three Marks)
(2) Why do cars (usually) whine in reverse?
(3) Which produce more torque: petrol or diesel engines? (simple answer) Which produce more horsepower? (Two Marks)
(4) True or false: turning on/ up electrics in your vehicle lowers its mpg (until you turn them down/off again).
(5) What is the land speed record? (Three Marks for within 50mph, two for within 100mph and one for within 150mph)

(6) When, in what country and by whom was the first car as we know it made? (Four Marks - two for the year, one for within ten years)
(7) Can you name the top five car manufacturers? (Five Marks)
(8) What are the most-sold cars ever, in categories: single model; one model but evolving over generations? (Two Marks)
(9) Who is or was the most successful Formula One driver ever, and which constructor is or was the most successful? (Two Marks)
(10) Can you name the following parts of a car: reduces exhaust noise; 'clamp' the brake pads against the brake discs; inlet X and exhaust X supply air (and fuel, in an old-school petrol engine) to the cylinders, and direct exhaust gases from the engine towards the outside world. (Three Marks)
(11) What are these dashboard lights telling you? (Five Marks)

(1) Systems which use compressors to force more air into the cylinders. Turbos are powered by the exhaust (exhaust gases spin a turbine, connected to a shaft, connected to the compressor wheel), while superchargers are powered from the engine (crankshaft - pulley - serpentine belt - pulley - compressor wheel). We can leave electrical models and intercoolers for another time.
(2) The usual transmission gears (toothed wheels in this context) are helical, i.e. have diagonal teeth, which engage more gradually and smoothly, which is a more effective design. They are more expensive to make than spur gears (teeth at 90°), and as reverse is only used at low speeds and for a few seconds, they don't bother to make the relevant gears for reverse helical. I suppose the whine also alerts people to a vehicle reversing.

(3) Diesel; Petrol
(4) True
(5) 763mph (slightly faster than sound) - achieved by ThrustSSC, propelled by F-4-style jet engines, in 1997.

(6) 1886, Germany (the German Empire then), Karl Friedrich Benz
(7) Volkswagen, Toyota, Mercedes-Benz, Ford, General Motors
(8) Volkswagen Beetle and Toyota Corolla
(9) Lewis Carl Davidson Hamilton and Ferrari
(10) Muffler; callipers; manifolds
(11) (a) Low coolant level
(b) Engine overheating (coolant too hot)
(c) Handbrake on, and/or brake problem (usually low brake fluid level)
(d) Low oil level
(e) Low oil pressure
In these you can have half a mark for getting the gist, i.e. 'brake problem', 'oil problem' etc..

To complete the course you need 16/31! Less than that and you crashed and burned.

Even though I did once return to a dealership once to report light 11c would come on sometimes when stopped.

(3) is going to depend on how much air you stuff into the engine with forced induction. Assuming identical displacements, a petrol engine will have both better torque and horsepower if they're naturally aspirated. However, forced induction changes everything since diesels can handle far higher levels of boost, they don't have to worry about knocking or detonation so you can cram a lot more air & fuel into the cylinders to make more power & torque.

16/31

Barely I pass similar my driving examination am lucky #6 I guess year & country and receive 3/4 otherwise I fail haanji

There is the official 763 for thrust on land speed
Then the most likely around 900 unofficial that happened after another rocket sled incident of the 43 g.
Who knows when they'll declassify all of that nonsense. It's the sr 71 but on land top speed kind of thing

I got Lewis Hamilton and Ferrari and some of the dash lights - I also knew super and turbo had to do with air.

I flipped petrol and diesel.

I got 7
