Context: I drive a 15+ year old SUV, and I am no longer in the position to just replace everything should anything bad happen. So sadly I will have to buy a newer car at some point. Hopefully not anytime soon 🤞🏼🤞🏼 But, I noticed when shopping with other people that newer cars sound weird. My knowledge of car troubleshooting is little more than sounds good/sounds bad, looks good/looks bad, smells good/smells bad, feels good/feels bad.
So, how are newer cars supposed to sound?
Regular gas cars should sound like normal muffled engines (comparable to your experience with 15+year old SUVs). Outside slight improvements in cabin isolator material which can dampen or lessen road noise and exhaust noise, they should sound roughly the same.
The injectors can sound like loud clicking or tapping occasionally, and depending on the make/model it can be quieter but usually audible inside the vehicle when at drive-thrus or when idling.
Hybrids usually turn the engine off at stops/low speeds and can often have a brake pedal that people complain feels spongey or loose, but due to how hybrids work that is normal since they use the electric motor more than the actual brake pads to stop in most cases. So hybrids usually have brake pads that last a really long time compared to non-hybrids.
Definitely shouldn’t sound loud unless it has some aftermarket exhaust or the cat was stolen.
This is helpful, thank you. I wonder if it’s the injectors I was hearing then that sounded weird.
Thanks for the heads up about the brake pedal. That would probably freak me out especially if the car’s detection system beeped at me for a random reason while I was braking.
If its not the injectors, then its the high pressure fuel pump, but they sound very similar with a loud clicking. A similar sound to lifter ticking, if youve ever heard that sound before.
Hybrids will also turn the engine off while driving sometimes, so that can sometimes scare people as well. So don’t be too scared if that happens on a test drive.
Yeah I really hated driving hybrids and EVs around because of the brake pedal. I daily drive a car without power brakes or ABS so I am used to a really hard pedal and manually pumping the brakes. Hybrids and EV brake pedals basically just felt like another throttle pedal to me.
Depends on the car. If you’ve heard a 4 cylinder you’ve heard most of them. GDI engines have loud ticking fuel injectors at idle, this is normal, they’re squeezing 600-2000 PSI of fuel pressure into the combustion chamber. Unfortunately, while a lot of modern cars have 4 cylinder turbos now, they are almost all smol turbos that spool at 2000 and run out of breath past 4000. They also don’t make any cool turbo noises.
Engine will turn itself off when you come to a stop and it’s warmed up. Don’t worry, EV motor will get you going while the engine restarts. Lots of stop-start engines will start up as soon as you let off the brake pedal and be good to go by the time you move your foot over to the gas.
Also, engine may stay off for a bit depending on your driving mode and speeds. This is good, especially with a PHEV (Plug-in Hybrid Electric Vehicle), which has a small “for around town” battery it can drive on. Saves you in gas to charge it on the wall for those <40-mile grocery runs. Can also save you a gallon or two on longer trips by running on battery for a few before firing up the engine.
A lot of modern cars also play fake engine noises through the speakers so people who are allergic to the sound of a quiet car can pretend they have a V8 under the hood.
If you want a car that still has an angry growl but is good on gas, get a Subaru. Still a very “personality” car in this day and age, even with a CVT and a hybrid drive system. She makes lots of noises and demands your regular maintenance care (on-time oil and transmission fluid changes, regular oil level checks and topoffs if needed), but will last a long, long time if you do.
Most main stream, dare I say appliance cars, have what is called a rattly ass 4cyl. Not to be confused with nice sounding 4cyl engines.
I’ve also noticed new cars sound bad.
