22 Supra Fuel Economy

[johnnyskids]

OP, that does seem like rather poor mileage. Do you drive up hill both ways, with a head wind, and the e brake on? I’m just kidding of course but I would check tire pressure, and try switching into comfort mode and maybe not using the brake and gas pedals like on off switches. Are you one of those people who drive with both feet (right foot for gas and left foot for brake)? The reason I ask is a lot of people who drive like that tend to rest their left foot on the brake pedal and that can cause the brakes to make small contact and greatly impact both fuel economy and the life of the brakes.

At about 12,000km... fuel economy is worse than OP at around 14.5 MPG in the city. I drive it only in manual mode, shift and run it at high RPM. You know...like a sports car lol. Our 992 C4 gets about the same fuel economy in the city, and both are perfectly normal and acceptable to me. On the highway, both the Supra and the 911 get into the mid-20s.

2023 MT at 1k mi with JB+, rarely highway drive at all so I can't speak to hyper-mileing it. Always drive it like it was intended, struggle to break above 19 MPG on 93 ? Honestly not bad considering most the miles are ripping around the Appalachians.

This is my problem. '22 3.0 Premium, and I really want to drive in normal mode and not waste gas, but my willpower is too low. Once the car heats up enough, I can't stop myself from switching to sport mode and driving like bat out of hell?

I wish I was capable of driving normally like some of these other people, lol.

I usually average around 28-29mpg with a good mix of hwy and city driving. I see 36-37mpg at hwy speeds and I do actually keep mine in sport mode 100% of the time, I just swap over the transmission setting to normal when I'm driving hwy to maintain good fuel savings. I really wish we could program in a "mymode" of sorts so I didn't have to toggle transmission mode on/off although it isn't super difficult to do.

Same here, basically. All of my driving is on surface streets. The only time I take the highway is when the onramp is clear and I can do a high-speed pull. Driving around town I rarely ever shift past 3rd, as a result, most of the time the economy meter is reading 18.x mpg.

hahaha totally feel you. guess the way forward is to hope for better tech in production cars lol. I saw the HKS Advance Herritage program for RB26 & think if car manufacturers can incorporate pre chamber ignition, dual plenum intake manifold (pre & main plenum), dual smaller injectors per cylinder, twin scroll single vertical turbo (with Borg Warner EFR's techs), individual throttle bodies, & Porsche's newly patented 6 stroke design with the existing VVT & direct injection tech, it would breathe new life into internal combustion engines.

for a straight 6 with such techs, they can easily create smaller engines at 2.0 litres with a lower center of gravity, with probably peak figures of 400+hp & 500+nm. if manufacturers are willing to invest as much as they did in engine, turbo, suspension & brakes developments over the decades into chassis (titanium alloy or other alternatives), it'll be even more insane & they can detune it for production cars & let modders take care of the tuning if they don't mind sacrificing some fuel efficiency. yes, it'll be costly, but so were ssd when they were 1st launched to replace hdd in high performance computers. but I feel that at the very least, the direction has to be there. throw in 6 or 7 speed manual for the people.

sadly with the direction of where the market is going, I doubt we'll be able to even see a Japanese straight 6 again.
