Tire Pressure Monitoring System

TPMS became mandatory in all new vehicles in the US after 2007 following the TREAD Act, which was prompted by the Firestone tire controversy.

5W-30

5W-30 is preferred because it provides excellent cold-start protection while maintaining good high-temperature performance, improving fuel efficiency by reducing internal friction.

To reduce harmful emissions

Catalytic converters convert about 90% of harmful emissions into less harmful substances through chemical reactions using precious metals like platinum and palladium.

ABS

ABS (Anti-lock Braking System) can pulse brakes up to 15 times per second, allowing drivers to maintain steering control during emergency braking situations.

Hybrid engine

Hybrid engines are particularly efficient in city driving because they can recover energy through regenerative braking and use electric power at low speeds where traditional engines are least efficient.

Every 6,000-8,000 miles

This interval coincides with typical oil change schedules and helps ensure even tire wear, extending tire life by up to 8,000 miles.

Clutch

The clutch uses friction materials that can withstand temperatures up to 500°F and forces of several hundred pounds to smoothly engage and disengage power transfer.

More power from smaller displacement

Turbochargers can increase an engine's power output by up to 50% while potentially improving fuel efficiency, allowing smaller engines to perform like larger ones.
