That Horrible Engine Roar

This car is not meant for climbing hills! The gas engine can rev very high and the noise is terrible. On an occasional drive from Santa Cruz (coastal California) to Silicon Valley, I have to pass over 1800 foot mountain; in places the engine really winds up. Then this past week we drove from coastal California to the Kirkwood ski area at 7000 feet. The engine noise was intolerable!

I am sorely tempted to sell this car after that experience. I know that seems extreme, but I really think the engineers made a serious mistake in this design.

Does the Accord Hybrid have the same awful drive train?

And your mpg?

So, climbing that elevation, can you tell me what kind of mpg you are getting?

Same Drive train

To answer your question, both the Insight and the Accord hybrid are advertised to have the Gen 3 hybrid system. So, I suspect that even though the Accord has a 2L engine, with the additional weight of the Accord, you would likely find it also gets noisy during steep climbs up a mountain.

Not precisely, because I didn't reset trip odometer when we began climbing. Using the "Current Drive" number from the power flow screen, I think the lowest value I saw was around 28 MPG. We stopped in Stockton and then continued to Kirkwood; it looks like the first 25% would be mostly flat and then it's all uphill. I can't complain about the MPG over such a long uphill. Of course coming back down I got around 120 MPG! And then we stopped for lunch and continued on for about 8 miles to another town and got 199.9.

I have seen it stated in various articles that the Insight has CVT transmission, but this is wrong. Car and Driver has a nice article explaining the 2018 Accord Hybrid drive train and I'm pretty sure it is the same as Insight (except Insight components are smaller, less powerful). I think that explains why the engine gets so loud - with no transmission, the gas engine has to rev to very high RPM.

I had the same experience going uphill this past weekend. The noise was so unbearable I had to crank up the stereo to drown out the noise! I also had to go below the speed limit since it was reving so badly, I was nearing the gray area of the power gauge.

I agree about the horrible engine roar. That being said, when I travel up big hills (Route 287 from Parsippany to Mahwah, NJ) I have had some luck putting the car in SPORT mode with maximum regen with these hills. ECON just doesn't get it done on hills/ mountains and it takes so long to go up hills that you are losing time. "NORMAL" is not quite as strong as SPORT. The idea is to get up the hills as soon as possible so as to minimize - if possible - the loss of mpg. I have found that maximum regen very slowly can eventually give me additional battery charge even going up consecutive hills (with some flats). The idea that I have more battery charge to play with and get up the hills sooner with SPORT makes that my favored choice. Please note that SPORT and ECON at hard acceleration both seem to have similar mpg penalties on a second-by-second basis (as per the horizontal mpg line in the dashboard graphic). Thus, why NOT take the slight penalty of SPORT to finish the hills ASAP?

That's very interesting to hear about using Sport mode. But of course that enhances the noise INSIDE the cabin, thanks to ANTI-noise cancelling special effects.
I will try sport mode on commute, where I have a 3/4 mile climb of about 400 feet.
I don't think it would help when going to Silicon Valley, where the climb is around 1200 feet over 6 miles (some parts are very steep).
It certainly wouldn't help driving into the Sierras with 7000 foot climb.

Hoboken Made a Great Suggestion

The suggestion of using Sport mode on steep hills makes sense. In simple terms, a hybrid is an electric car with a gasoline powered generator. The engine is really there to keep the battery charged, and when necessary, provide supplemental mechanical power to the wheels. So, when the battery drops below the minimum charge level, the engine has to work hard to play catch-up recharging the battery while also taking over more of the work turning those wheels. That requires high engine rpm. Unfortunately, it is an unavoidable consequence of the vehicle design. The longer you can keep the battery charge level above the minimum, the less time the engine has to speed up to make up for lost battery power. One obvious solution would be a bigger engine, but that would add weight and cut down the mpg. So, I guess it comes down to an engineering trade-off. If you live in a mountainous area, a hybrid may not be the best choice. Too bad nobody explains that before people make a vehicle purchase. I appreciate Hoboken's suggestion. It is at least a partial workaround. We all need to learn how to best utilize hybrid technology.

Last week I drove from Bay Area to Orange County. On the hills I kicked it into sports mode and barely had to touch the gas. In regular I was stepping at least twice as hard and the car was having a hard time. Sport was still loud through the Grapevine stretch but power was good.

Overall I got about 46 mpg both ways.

I mostly drive it in the city and in traffic. But when Iím on the freeway there are hills. I found that sacrificing a few mpg for the stretch didnít hurt my overall numbers and it felt a lot less straining on the car.
