"Honey, I only bought the Corvette to save on gas money!"

My old 2002 SS Camaro would get that same 32 on the highway like clockwork. Love that 6th gear. 1400 rpm at 70 mph is incredible.

Really impressive considering it was carrying 725 lbs along the way.

It's amazing how efficient they can be when you're not ripping on them. But it's a Corvette... so it you have to rip it. I have to applaud these guys for being able to restrain themselves for this brief time, for science! This is important data that nobody will ever be able to use!

I've heard on the forums from a long time ago people saying they were getting 30mpg out of these. This confirms it. Impressive!

I had a 94 Firebird Formula with LT-1 that regularly saw 33 MPG on the highway, so your results come as no surprise to me. Efficiency and Aerodynamics make a huge difference.

When I was doing research before buying my 2008, I was told I would get 30 mpg on the highway and I thought that was ridiculous for a 436 hp car. My first drive in it was from Edmonton, Alberta to Ottawa, Ontario and it turned out to be true. Nobody buys a Corvette to save gas (and in town you won't) but it is a nice bonus. And those gas pump barrier things are maddening as they are perfectly placed to harm your door! The other positive feature for long trips is the amount of storage space in a C6. Nice video!

Now do the IKE in that baby.. I want to see how many brake applications are required on the way down with you two in there... Gotta have the payload capacity maxed out!

Nice! Back in the day, I bought a new 2006 Pontiac GTO (Holden Monaro) with the same LS2 engine and the Tremec 6-speed manual. I easily got 31 MPG on the highway, when I used the cruise control. Great engine setup. 400 hp, not too wild, but just enough.

I drove a C6 Z06 from Naples to Miami at 80mph and got 28mpg. I was impressed.

Love the Lemmy Kilmister shirt Nathans wearing! My 2014 ZL1 gets 25MPG on the highway....6.2L supercharged and pushrods! Why fix something that ain't broke, GM did an amazing job with the LS powerplant...👍👍

On a 700 mile trip from PA to Michigan my 2010 C6 convertible with the six speed auto averaged around 28.3 mpg at an average speed over 70 mph. For at least 500 miles of that I’m certain I was cruising at 80 mph.

My 2005 C-6 convertible gets 28 to 29 regularly, however I usually set the cruise at 79 (75 speed limit) and it’s a 6 speed manual.

Nathan love the T-shirt rip Lemmy I thought everybody knew Corvettes get good gas mileage if you don't drive like a maniac

My wife and I took a 4000 mile trip in my dad's 07 corvette and we averaged 42mpg on one tank when we where in Arizona that was fill get on the interstate and get back off to fill back up no city driving we where running 80 and had the ac on and 35mpg as a whole for the trip that's not using what the computer said that was hand figuring every tank and it's a 6 speed as well I absolutely love the car! Looks almost identical to the one in this video

Got 29.5 at 80 in my 99 C5 and 26 in my 98 WS6

It was nice to see those two guys in the video together. Great video as always everybody

Love it... Sometimes the simple videos are some of the best... Then again, just Nathan and Brendan driving around is pretty damn entertaining... I can only imagine the outtakes for the video...

Got my Cammed 05 LS2 GTO as high as 27mpg avg hwy and i get 22 combined on my 50 min commute to work. The T56 + 3.42 gear is beautiful for it ❤️

I had a C5 with the base 5.7 in Hawaii, and averaged over 30 with it as a daily driver.

That intro music is what Mark Rober uses, not used to hearing it anywhere else especially a Corvette video 😊

Just to be clear we love Brendan. Massive addition to the channel ❤

Could you imagine what it would get not hauling 700 lbs up front 😂

Have a heads and cam LS1 with 4.10's still getting about 25mpg's - these things are a true gift from the car gods.

I achieved 29.6 MPG with my 2017 C7 automatic Grand Sport in Eco mode on Interstate 10 from Fort Stockton TX to Junction TX with the cruse control set to 90 miles per hour.

I always look forward to the videos with Nathan and his son. 🍻 cheers.

Great job guys,, good sense of humor.

I looked at the comments and I didn't see anyone mention, not even you guys , that it is normally aspirated at a mile high and got 32 mpg. Amazing.

Great video. Love the Lemmy shirt bro! 🤙😎

Yup the LT, then LS’s with the 6 speed got some amazing mpgs. The autos weren’t terrible, but being rear end ratio and transmission gear limited. I have a 2000 z28 with 3.23 gears stock, and before I modified it I got a solid 25 mpg on the highway. Oh and fyi it was rated at 23mpg. These LSX motors are incredibly fuel efficient given the right fuel and “mild” driving 😉. Now that same z28 with a “medium” sized cam, stalling torque converter, and 3.73 gears ( Full weight ) still gets 22-23 mpg. Plus I love to hear that amazing cammed full exhaust sound…

Back around 2007, the c6 z06 tied the 911 and F430 on the Top Gear track (look it up, top gear still has the c6 z06 episode on KZfaq). Imagine that, a FRONT ENGINED, $70,000 c6 z06 Corvette that gets 30 mpg highway tied the TRACK time of $200k to $300k euro exotics back then.😁 Now, of course, GM did not make it all leather interior (I criticized them for not making it optional back then), true, so it has plasticy dashboard, but that could be added afterward if you wanted and STILL be way cheaper in price than the 911 or f430 back then. 😨

This was an informative video. I read many years ago that this generation of Corvette could achieve 30+ mpg. The C6 and C2s are the best looking Vettes Imo.

They're low, light, and powerful. When driven in a relaxed fashion, they get great mileage. If you drive one with your foot in it, the mpg will be what most would expect. Even the 7 liter in the Zo6 can get killer mpg.

Owned a 02 Firebird, and regularly got 32mpg. The real secret is 3.08 gears in the rear. Keeps the revs nice and low for cruising. As soon as you jump up to 3.73 or 4.11, yes the car gets way faster but also the mpg drops like an anchor.

Thanks, nice video!

I owned an LS2 C6 that gave me 32.8 mpgs in the hwy w cruise control activated. Way better than any published tests. I sold it in spring after enjoying it for many thousands of miles, and 100% reliability. Great car!

I maintained a friend's corvette,C5 that he drove between Colorado Springs and Denver and was getting into the 30's with it, he would drive his duramax on the really snowy days

That was interesting. Also maddening that this Vette gets better mpg than my Honda civic

For reference: I get 22.6 mpg with a Mazda RX-8 on long german Autobahn trips. So 30 mpg for the Corvette is real impressing. The engine seems to have a low inner resistance and does not suffer under low load inefficiency.

Not surprised my old 95 Roadmaster with an iron LT-1 would do 28-30 on highway.

I regularly receive on the Highway between 28 & 31mpg. But the vast majority of My driving as like most ppl who drive is City. The best I received in my last Corvette a C6 427 hovered around 15, which is still better than my last Mercedes-Benz Brabus! My new C8 should do minimally better considering it's the E-Ray though a Callaway❤😂. Ppl just ❤to hate on 🇺🇸vehicles, but nary a peep when it comes to 🇩🇪vehicles 🙄🤔🤬 or reliability. So looking forward to my C8 Callaway once back in Denver, as it's going to be my Daily. No need to carry 50ppl in my car. My vanity plate: I8ATSLA 🤣

17 Camaro SS. I regularly get 28-32 on highway jaunts if driven frugally. 460hp. 6spd. Love it.

My 01 C5 got 30+ too. 6sp manual. Aerodynamic body, good power at low rpms. Not screaming like a 4 banger.

Even my '87 L98 C4 gets upwards of 25mpg when cruising on the highway. Everyone is always shocked when I tell them.

My wife and i decided to replace her 16 scion tc for an 08 vette with the ls3 and A6. We took it from ohio to south carolina and it it did 28.4 mpg doing mostly 70-80 on the highways with us and all of our stuff. The tc also got horrible fuel mileage for being a 4 cyl and she saved alot of money on insurance switching to the vette. So we did save money in the end going to a corvette 😂😀

Cool shirt Nathan! 🤘

I took an 8600 mile western road trip in a base 2011 C6 with the manual and the taller differential of the base Corvette. I averaged 25.1MPG covering interstates from Illinois to Arizona, up through Utah and Nevada to the Redwood Coast up through to the Olympic Peninsula and back home to Illinois. I had very high speeds on some rural areas and on the Bonneville Salt Flats. Great performance for a car with 430HP 6.2L V8.

I have a full bolt 2006 Corvette C6 Z06 with a tune. I did a road trip from Vegas to Seattle and averaging 24-30 mpg hwy running premium.

We bought a 2006 C6 in Texas and drove it back to Denver and averaged 31 mpg over 750 miles- with an automatic transmission!

Had an an 02 Z-28 6 speed. I saw 28 mpg highway and thought that was amazing especially since at that time, few cars had 320hp to go with it. 32 is amazing.

I'd routinely get 30.5 MPG with my 2015 Mustang GT (6 speed manual but 3.73 rear end) back and forth between Columbus Ohio and Indianapolis Indiana - if I didn't drive like a maniac - I'm amazed I never got stopped for driving under the speed limit - it looked odd to most passing me....

A light car with a small cross section and a tall top gear is very fuel efficient when driven at steady speed. TFL is the real Mythbusters!

I hit over 30 regularly in my C5, my best being 33.4. Have fun with it and it gets thirsty, cruise it down the freeway and it just sips the fuel. Being slippery in the wind has a lot to do with it.

Low end torque and the right gears really helps but using premium fuel is somewhat painful these days

I own a 93 LT1 Camaro, put a new 385 ci stroker, 13.5 to 1 comp. 625 hp. NA, tuned on 93, the milage has improved to 36 mpg. 6th gear average 75 mph. It gets better milage than my sister in laws Prius.

I’m not surprised. The Corvette is known to be a great highway cruiser. The High End models I believe do pretty well with fuel consumption as well?

I truly miss my C6 with the LS2... Yep, if I drove it gently, I could get 30 MPG on long freeway trips. That was a big "if" though :) My only complaint about the LS2 was the piston slap when it was cold.

Best I've seen in my '06 six speed 'vert is 33 MPG at 80 MPH from Dallas to OK City. Double overdrive rules. That's why I put a Gear Venders over drive behind the 4L60 in my '69 Chevelle SS396 'vert.

I regularly get 35 mpg out of 09 2lt corvette at 80 on Texas interstate highway.

FYI : $4.69 a gallon for premium is cheap. Try buying gas in California. Close to $6.00 a gallon here. Thanks JB.

RIP Lemmy. Love the Motörhead shirt.

@6:15 completely accurate Have done this with multiple vehicles, auto to manual, full size to compact, fuel injected to carburetor, 2.0L to 6.4L. Don't complain about fuel prices if you're not maxed out on efficiency. Sometimes up to 33% difference

Sweet video guys, does that car have cylinder deactivation Lol?

My 08 C-6 gets 27 mpg with a 430 hp engine. I've always been impressed by that. I've never driven it in 6th gear for very long; just 5th gear.

Had a 4 banger with a six speed manual (rated at 28 mpg highway) get 33.4 on a 600 mile round trip, at 70 mph with the air on. I was blown away. 6th gear made all the difference.

I got a c6 grandsport with a ls3, cam, bolt ons ect ect. Drove it 2 hours away, raced and drove it 2 hours home and averaged 26mpg

Bought a 2006 about the same time as you purchased yours and they do get excellent gas mileage. Seeing upper 20s in mixed driving in a convertible with an automatic. My 2008 Mustang GT with a manual gets 2 mpg or more lower. All the reasons you mentioned plus the rear axle ratio account for this.

I had a c5, and it was amazing for road trips. I second the claims in this video, although it's an even better c6.

Nathan killing it with the rock t-shirts again, this time Motorhead!!

I had an '06 6 speed coupe and took it from NY to STL - I did it in 14 hours and change and only needed a single stop since I was getting 29mpg cruising at 85mph with the cruise control on I did track my mileage on that car - over 9400 miles my avg mpg was 22.6mpg. My best tank was 30.1mpg on my way to NY Here's the 2 entries from my NY to STL trip - the 7/6 entry is from Date - Miles - Gallons - MPG - Cost 7/6/14 477.00 16.940 28.16 3.799 7/5/14 502.10 17.128 29.32 3.659

Kenny T shirt in a C6 freaking awesome !

That is impressive 👏. I believe some vehicles powerplants are so under powered it causes them to be less fuel efficient. You've also got to drop the RPM's at highway speeds and I believe that lots of manufacturers fail to build this into the drive train.

Those 3 custom holes In the front fascia were actually punctured in there by Matt Farah on another channel that was giving this car away also not for a front license plate but to help as an air intake!

I believe it. Recently I needed a rental car to get from California to Nebraska and only thing they had available was a 2021 Mustang GT. I had no choice but to take it and cruising at 70 mph the whole way I averaged out at 36 mpg. I was blown away lol, and no I was not going based off my tripmeter I went off how many miles I was driving and how many gallons I used

This is great! I both love and hate that more people are finding this out. Big V8s are very capable of getting good mpg. My old 94 cadillac with a 4.9 got about 27 mpg on the freeway going 65. And I know there's a tuner who has got a c5 corvette up to 50mpg. People think they are huge gas guzzlers and they can be. But if you drive them like a granny they can also be very fuel efficient cars.

I regularly get 25+ mpg in my 1987 C4. The car has the GM1 rear gear and at 70 mph turns 1900 rpm. Most fuel efficient vehicle I own!

I need one now

It's not a Rush shirt, but Lemmy is acceptable. Carry on.

Love the Lemmy shirt !

The 6th gear in the C4s was so tall, that you couldn’t - or shouldn’t- use it below about 65 mph. I’m sure the C6 ratios were similar. When a V8 spins that low of rpm at highway speeds, the throttle has to open more just to hold the highway speed, since the V8 engine isn’t really ”power” efficient at less than 2000 rpm. An open throttle and low rpm on a 2 valve engine that’s not working hard means mpg. This idea - back in the 90’s - told me that hybrid powertrains (work an engine slightly harder to drive the car - AND - to charge a battery) will work. Not necessarily a Corvette thing (hybrid powertrain), but look where we’ve come since - 55+ mpg Prius, and the like. And if you go full electric - even more efficiency!

Yep! C6’s are great on gas! Have owned 12 in the past 3 years! Daily drivers as well! Also so reliable! LS2’s are better in gas than the LS3’s!

75 at 1800rpm is amazing and what a beautiful car!!

I had a Trans Am (carbureted HO with 5spd manual) in the early '80s that got about 30mpg on the highway too. And, yes, even little Toyota Corollas did not do that well at the time. But once you got off the highway and drove it around town it would average about 16mpg in mixed driving. The key to good mpg in those cars was cruise control. If you mashed it for even a few seconds that good MPG went down the toilet. The elephant in the room though is that it required high octane fuel. And that, my friends, meant that fuel cost per mile was terrible.

Yup. They're light, they're slippery, and you basically idle down the highway, I got 26MPG average in my C5 and I don't drive nice. GM did really well on highway MPG in general. My 94 Impala SS, which is a 4300lbs boat, loaded down with 700+lbs of passengers and luggage clicked off 28MPG on a 500 mile highway trip.

I want to see older cars like a fox body with transmission swaps I believe that they don’t need more hp just a better transmission to perform like newer cars because they are way lighter

Drove my 505 HP C6 Z06 to Corvettes of Carlisle and home again 8 hours each way and averaged 30 MPG.

Having a bigger engine doesn't necessarily mean it's going to burn more fuel for any given drive. The biggest key for better fuel efficiency is gearing. When the engine has more power, it doesn't need to spin as fast to keep things moving. For regular road use, you can use a lower differential gear ratio, or a transmission with a lower overdrive gear ratio. I used to have an '03 Mustang GT (5spd manual) that was equipped with a rear end ratio of around 2.70:1. It was not the fastest in acceleration (for a mustang), and it was a convertible, so it was also a bit heavier than most ponies. The 4.6 SOHC was smaller by a bit over than a liter, when compared to the engine in the Vette, (though that's somewhat made up for by the over head cam in the mustang, vs pushrods in the Vette). Most OHV engines are more fuel efficient than equivalent OHC engines, there's just less metal spinning around, so the engine has less parasitic loss. The engine will likely have a lower redline when compared to OHC counterparts, and will usually peak on power at a lower RPM - The slower you spin an engine, the less it has to fire, the less fuel gets burned. Additionally, OHV engines usually have fewer valves, so even by default, it can't get as much oxygen flowing through, so less gas can be burned. At 75mph, the engine was turning at around 1250rpm. -I took the car on a road trip to FL from NJ, and I was blown away by how well the car did for mpg's. By the end of the trip, I calculated that it had gotten an average of around 37 on the way down, and about 34 on the return trip. (on the way back, I may have been exceeding the speed limit by a little bit, which accounts for the difference in economy)

Premium is 93 and some stations 94 in Toronto, Canada. 91 is mid grade, 87 regular.

Very impressive.

Legit Street Cars tuned his C5 for lean burn at low load highway cruising. He got 40 mpg on the highway. Any skilled tuned with HP Tuners can do it. Absolutely no risk to the engine. As soon as the load increases over minimal levels, it goes back into the OEM tables. Perfectly safe to cruise on the highway at 15:1 AFR.

Could this be considered a tow test with the amount of "ballast" added to the cabin?

I'm not surprised though ...I had a 1993 Camaro Z28 with a 5.7 LT1 and on any given day I was averaging about 30 mpg so yeah those engines are surprisingly efficient.

I own a '08 C6 with the LS3 and love the fact that I can also get 30 MPGs out of a 430 horse power car

Cool thanks 👍

I wish i knew my mpg, bht whenni still had my ls1 in my 01 Z28 and 4l60, i could go from houston to tyler tx on 1 tank. Still have 1/4 tank left and that was crusing 75 most of the way with a few tripple digit romps on some long straights for miles at a time. It was a beast on those mpgs

i had a 03 mustang gt 4.6 an couldn't even get close to that number, wow thats good

My dad has a 2004 le mans Vette. I drove it a few times probably 10-15 years ago and remember getting 20mpg cruising around town/highway without heavy accelerations. Older cars seemed to get better mpg with partial throttle than most of today's cars I've driven

Nice Lemmy shirt. 🤘

I had a 06 GTO with the 6.0 and six speed and got 32mpg from Milwaukee to Indianapolis
