2024 Toyota Prius: Toyota’s fourth-generation hybrid arrives in spring with gorgeous new fastback styling. The base 1.8-litre four-cylinder engine and electric motor produces a net 193 horsepower.

The plug-in hybrid Prius Prime gets a 2.0-litre engine, which increases net output to 220 horsepower. A panoramic moonroof is standard, while energy-generating solar panels are optional.

AUTO TRIVIA

  • Actor and part-time racer James Garner drove the pace car at the Indy 500 on three occasions: 1975 (Buick Regal); 1977 (Olds Delta 88); and again in 1985 (Olds Calais).
  • The current octane rating system for gasoline was derived by Sir Harry Ricardo, a British engineer who studied the anti-knock properties of various combustible fuels during the 1930s. A higher octane rating means a higher resistance to uncontrolled burning, referred to as detonation.

WHAT’S UP, AUTO DOC?

Air gets into the braking system when the fluid-filled components are replaced. The result is a spongy pedal and ineffective and even dangerous stopping performance.

Removing the air necessitates “bleeding” the system, which involves opening the valves located on the wheel cylinders/brake calipers at each wheel, one at time, and forcing out the fluid and air with pressure from the brake pedal.

Unless you have brake-shop equipment, this usually takes two people and the following oft overlooked tips:

  1. Make sure the reservoir of fluid is full and that you have enough fluid to refill it often.
  2. The person in the vehicle holds constant and steady pressure on the pedal.
  3. Begin with the wheel farthest from the reservoir, usually the right rear.
  4. Do not pump the pedal while a bleeder valve is open as doing so draws air back into the system.
  5. Each time you bleed a line, refill the reservoir and secure the top/filler.
  6. A clear plastic hose pressed over the bleeder screw will allow you to drain the fluid into a container instead of letting it run all over the parts and onto the ground.

AT AUCTION

1963 Chevrolet Corvette Sting Ray, sold, US $316,000: The first year of the second-generation Corvette coupe is known for a rear window that’s bisected by a raised body line that runs from the roof to the tail.

The resulting split-window Corvette was a one-year-only anomaly, which makes the car incredibly rare. As part of a complete mechanical modernization, this ’Vette’s original 327-cubic-inch V-8 engine was replaced with a 6.2-litre LS3 V-8.

The suspension, brakes and transmission are also new and the interior has been fitted with leather-covered bucket seats, tilt steer and new instrumentation. (Source: Bring a Trailer)
