That's getting a bit weird and unnecessary and some owners could remove them or unplug them or whatever to get rid of the fake sound. Then, I think BMW was first to have a dedicated audio speaker on the firewall or under the dashboard that started putting some fake engine noise into the cabin of the car. Do some spirited driving of those cars and you'd really hear a bit more intake noise. Then, I think BMW was first to have a plastic intake pipe that connected to the firewall in the engine compartment so that some of the intake noise was channeled into the passenger compartment. You'd find plastic molded intakes on engines that occasionally had some resonator chambers (like a bulge that was just an extra part) and that was to make sure the air rushing into the intake didn't have some weird resonation that sounded terrible. Nothing wrong with doing that in a limited way just the same way as they make doors so the sound is a nice, solid "WHUMP" when you shut a door.įirst it was just making sure the intake and exhaust sounded good. They're talking about the sound artificially piped into the vehicle, not outside noise that's a courtesy for pedestrians.Ĭar makers started tuning sound to make the inside of the vehicles sound better or more sporty. I use cruise control a lot more in an EV to avoid creeping over the speed limit unintentionally. Though I did have to adjust to a silent motor in my EV since you can't judge speed and acceleration by engine noises. I think Hyundai is generating some fake piston engine noises for inside the car in this model, with gear change noises and all. It's usually some sort of high pitched whirring noise.
Some sort of noise is mandated outside the vehicle for safety. At least they didn't include "Poorly Tuned Harley" as a sound option. That sounds like it could be obnoxious and an easy way to piss off your neighbors. Hyundai set out for Ignition to emulate the sound of a turbocharged 2.0-liter inline-four There are three available sound profiles, and their volume can be adjusted from distant to in-your-face I know I depend on sound to hear vehicles coming up behind me when I am on my bicycle. I think the fake engine noise is legally mandated. Muta: Pocket Ninja: It's difficult now to say who's more contemptibly laughable: EV buyers who want fake engine noise, pretend gear shifts, and make-believe transmission effects or vegans who want all their food to resemble meat products. If you're not already screwing with a complex geared (or CVT) transmission, it's just easier to make the DC motor capable of whatever top speed you're aiming for. But that's because it already had the DCT there for petrol engine reasons. but also let's get up to 70 on the freeway". You can feel it going through real gears when you say "drive in EV-only mode. A Kia Niro plug-in-hybrid, which has a super-compact 80 hp 'pancake' DC motor before its dual-clutch transmission. I personally have one of the few cases of that on the road. If you're already sending your power through a gearbox, you can use that to make the DC motor smaller. things like windings and permanent magnet strength. A DC motor has its greatest torque at 0 RPM but eventually has a speed where it's maxed out and basically can provide no torque at all (zero load speed). There can be reasons in terms of keeping the electric motor smaller or at its most efficient. I think the first season they ran, they had five-speed gearboxes, but it seems they're on direct drive these days. Iron de havilland: Is there any advantage to having a gearbox in an EV? I'm thinking in terms of Formula E.
