Will the bigger car with a smaller turbo charged engine use less fuel over the same three journeys than the smaller car with the bigger engine but no turbo? Both cars have Petrol engines.

important point to note about the SKYACTIV G also is that the engine in the Mazda 3 has much longer ratios with the gearbox in the 120HP trim. i do a frequent derbyshire to hampshire trip and i often hit 52-53MPG (75k on the clock, 2017 model). These engines in the mazda's are just stupidly economical considering how great they are.

@asphalthedgehog6580 4 месяца назад

Same here. Mazda 3 2017 with the BBR chip. The gearing (diff) is so long it does about the same speed in V as the 165HP version in VI.

@badbasic 4 месяца назад

You do know that long gears is nothing to be proud of and sucks the joy out of every car enthusiast? Oh, and also makes the car slower to accelerate? Oh, and also makes you less economic at lower speeds? Just sold my 2017 G-165 M3, wouldn't have enjoyed it half as much with that shitty gearbox they put into G120.

@asphalthedgehog6580 4 месяца назад

@@badbasic it's the same box. Differential is different. And mine has more torque than the standard G165. And it does over 65MPH in second gear, so you could drive it in second gear always on any B Road. And it uses less RON98 fuel. Does 0..60 in less than 8 seconds. Less economic at lower speeds? I drive from 36MPH in VI and then it does 3.5l/100km (67MPG). The lower the RPM the lower fuel consumption. See Conquer Driving

@@asphalthedgehog6580 Always driving it in second gear on B roads? You try to act like a petrolhead, but no real petrolhead would enjoy such a thing.

If you wanted some numbers for a cheap 1st car. The 1KR engine in the peugot 107, toyota aygo and citroen c1 regularly gives me 65+mpg i managed to get into the low 80s but that was because i was doing 50mph on dual carriage ways (not ideal). The car is ok for its purpose of city driving but not motorways as it feels gutless when approaching 60. Especially with multiple people and a 5 speed gear box. £20per year road tax and insurance group 3 out of 50 so its almost as cheap as you can get. So many more fun cars out there but for a cheap runaround its great.

@surena9451 4 месяца назад

@@AnimeWorld_1-2 In my experience turbo's (not talking about diesels) tend to fall in no mans land. At normal driving you barely ask much from the engine thus the turbo isn't being used much. Meanwhile the engine has a lower compression ratio to compensate for having a turbo so it doesn't do too well compared to a slightly bigger naturally aspirated engine. When driving it sporty, the turbo kicks in harder and you actually use more fuel than a slightly bigger engine naturally aspirated because there's more air in the cylinders than an N/A engine could suck on it's own and thus more fuel must be added by the ECU for the mixture to not lean out too much. In other words, more fuel usage. I mean yeah, you can easily ask for more performance from a turbo with a chiptune but at that point you are more likely chasing performance and not economy. So in my humble opinion I don't know where petrol turbo's shine the most. Like what is the best usage case for them? Not to mention having more parts that can fail if it doesn't improve economy by much is questionable to me for reliability.

@AnimeWorld_1-2 4 месяца назад

@@surena9451 ye I get your point overall you’re in the same position with a bigger NA and a smaller turbo engine I guess it’s just a cool piece of engineering or marketing the smaller engine might make people want to buy the car thinking that it’s more economical because “it’s smaller” turbo engines also will be more economical at low rpms as the turbo doesn’t have to work at all (depending on size of turbo tho) for me personally a cool feature abt 1.4 turbo engine is that insurance is somehow cheaper than on a 2.0l even though their performance is exactly the same lol

From technical side, apart from what has already been mentioned, a great deal of technological advancement has be put on the Mazda with their Skyactive engines. Apart from the high compression ratio, optimised intake and exhaust arrangements, weight loss etc. it all adds up. It's an area where average ordinary consumers don't care but I think the result speaks for itself and make the Mazda engine development team proud.

@Sir-Prizse 4 месяца назад

In my economical bare bones 2012 VW up! 1.0 (59 bhp) I manage 48.4 mpg without air condition or other creature comforts. If I take fuel-saving to the absolute extreme, I can achieve 53.46 mpg, but I'm also a bit of a hazard. You would think that such a small low power engine could be more economical. In comparison to that in my 1998 MX-5 1.6 (109 bhp) I manage an average of 31.4 mpg with sportily driving. The same driving style achieves an unimpressive 37.76 mpg in the up!. So if you drive the up! sportily, then you lose almost every advantage of the smaller engine.

@davidlang3625 4 месяца назад

This is a great bit of analysis Richard. Surprisingly close considering that these are two completely different cars. It is interesting to see the progress made in efficiency over the years though. I have a 1994 Mazda MX5 1.8. It is lighter, less powerful and slower to 60 than yours, but I only get around 35mpg in mixed driving. However, as it’s a bit of a classic now I tend to only use it on nice days with the roof down. That destroys the aerodynamic - lifting off the throttle at high speed feels like the brakes are being applied!

@mdfk667 4 месяца назад

This particular Leon does not have the ACT cylinder deactivation system, which is a game changer. It reduces consumption with approx. 0.6-0.8 or more liters across the board. For example, at 125 km/h (indicated, 121 GPS) it consumes 5.4l/100 km (75mph@52.3 mpg imp), or 5.0 at 110 km/h (69mph@56.4 mpg imp). These are numbers I've been getting consistently for close to 7 years, with the car (an ST, or estate) laden or not. Interesting test nonetheless.

@Enjay001 2 месяца назад

I had a March 2017 2 litre MX5RF from new and kept it for 6 years. I was constantly surprised and impressed by the fuel economy. On several occasions I checked the MPG manually and compared it to the car's computer, getting very similar results each time. Typically throughout the six years I had it, I was getting 45-48MPG. If I drove like an absolute angel, I could reliably get the MX5 to return 53MPG on my 27 mile, mostly rural, but good quality, commute. It was a thoroughly enjoyable car to own and drive and, in my opinion, one of the best looking cars on the road for the price. The only downside for me is that I am "leg tall" and I was right on the edge of the MX5 being too cramped for me.

@YesiPleb 3 месяца назад

I'm soooo glad I'm not the only one to keep track of their fuel economy on their cars. I've got a spreadsheet going back 5 or 6 cars keeping track of almost everything including ppl, mileage, where I fuelled up and I calculate stuff like mpg, pence per mile and also a comment column to say what the drive included like driving across the country on motorways etc. The best I've had so far was an old diesel M-reg Vauxhall Astra. Filled up at Exeter, drive to Scunthorpe and back on 1 tank and filled back up at Exeter managing 72mpg. I now drive a 61 plate VW Passat estate and drive for fuel economy. I remember driving from Exeter to Laindon and drive there in my Passat estate and drive there doing 60mph and it cost £25 with a car packed full; 3 adults, 1 child and loads of luggage in the boot and packed around us. Had to drive back quicker due to the health of one of the team being elderly doing 70-75mph and it cost me about £35. I read the road and try and let the car slow down on its own rarely braking hard (emergencies!) and slow acceleration all without being a nuisance to other vehicles. Read the road ahead and do my best to adjust the speed according to what's up ahead. Used the air con instead of opening the windows where possible to reduce drag. Even now I can get up to 66mpg around back roads and if on the motorway I get around 56-60mpg.

@YesiPleb 3 месяца назад

Forgot to add. I use the tank method to calculate as I like to let it run down to just under quarter tank left and fill right up every time. Cash is a bit low at the moment so had to put a pause on it for a bit.

@zipobob1 4 месяца назад

Richard, in my VW Jetta owners manual, under Eco Tips section, it mentions: "Refuel in moderation: A full fuel tank increases the vehicle weight. A fuel tank that is half to three-quarters full is best suited for city driving." Could you put the above statement to test to see what's difference in efficiency when driving with full tank versus half tank in your 3 typical driving scenarios. Keep up the good work🙏

@ConquerDriving 4 месяца назад

I don't think I would notice a difference, I would probably need a laboratory to measure that. We're talking about 20kg difference between half a tank and full. That's about 1.6% the mass of the car. One slight difference in road conditions will probably make a bigger difference to the result.

@Sergei_Mn 4 месяца назад

On the surface this advice seems unlikely to be a good one. My bet is whatever fuel you save by not carrying 20 or 30 kg of fuel (which is like 2% of an average car weight, and weight makes almost no difference in fuel consumption at constant speed, it only matters when you accelerate) you will burn doing extra refuelling stops.

But I found driving more aggressively and using its snappy upshifts at around 2000-2300 rpm, I now usually get 36-38. People think I'm an aggressive driver, but I'm convinced that's the characteristic of Mazda's philosophy of "zoom zoom," so that's how it wants to be driven.

That's also interesting. I had the 1.4 140 in a Leon estate and its interesting what it does compared to my golf 1.5 150 and it confirms what I suspected. The Leon was more economical in town (42 v 38mpg) But the golf is more economical at 70 (53 v 47). On rural roads they are similar. I'd have thought the newer cleaner engine would have been better. But there is another difference. Leon was a manual and golf is a DSG. That long 7th really helps it above 50. But less economical in town. Also worth noting is the 1.4 140 is a smoother engine that is less harsh at high revs. I think I prefer the 1.4 over the 1.5 although it's pretty good in general use there is no reward from pushing it. Got my Cooper S convertible for that. Less fun than an MX5 (still very good fun) but dog can sit in the back and come with us.

@zackw4941 3 месяца назад

You mentioned that the Miata is a small car, but the Cd isn't actually very good, at .35. The Leon on the other hand, seems to have .29. This is from a quick bit of google searching, but falls in line with what I would expect. I didn't try to look up frontal areas though, so the MX-5 probably still has less total drag, but it maybe closer than you think. There will be other factors too, such as gear ratios, tire size and engine tuning. This is a very good showing for the new generation of Miatas though! My 2000 Miata got terrible fuel economy! I drove it pretty hard most of the time and didn't have good conditions for fuel efficiency anyway.. But still, I averaged around 23 mpg US. Terrible for such a small car. The older models have very short gears and less efficient engines though. None the less, it is a sports car first and I do miss that car very badly.

You don’t lose any money on fuel by doing that but you do something very good to the engines.

I've found Mazda does seem to make very efficient naturally aspirated engines at the moment. My Mazda 2 has a 1.5L mild 'hybrid' (if you can call it that) and claims to get around 56 mpg on motorways, 58-62 on country roads, and about 47 in town. The downside of course is the need to change gears quite often, as its gear ratio seems to be quite long and can't maintain 70 on the more hilly motorways in 6th as the RPM is barely more than 2000.

There's a more accurate way. Fill both tanks until it clicks off. Do each run, but a decent one. Not short like 15 miles! Refil the tanks until they click. Work out the litres into gallons ( x by 4.5461) and then divide the milage by the amount of gallons used. This gives a true and accurate MPG and not relying on the computer.

The heater, *pulls* the heat from the engine, not the other way around. In fact if your radiator+intercooler are not enough for the engine to handle the track use, you can max the heater and open the windows, that will help reduce engine heat

I am definitly no traffic expert, but I have not seen any warning for the wall crashing corner,. In my country, many of the dangerous offramps have a sign for sharp corner and a speed limit, sometimes just 30 kph with a arrow pointing at the offramp., and maybe even a sing for "Dangerous Offramp" below the sharp corner sign. I think they could reduce the crashes if they just hang a 20mph sign above the blue sign at 14:18

Hello Mr. Fanders, A very interesting and insightful test and, in my opinion, a very important part of the correct handling of a motor vehicle in today's world; small fun fact, I have been driving my Renault MEGANE Grandtour Mk3 Privilege 2.0 16V CVT for over 14 years with an average consumption of between 7.38 liters and 7.58 liters per 100 kilometers, which corresponds to the standard consumption of 7.4 liters per 100 kilometers specified by the manufacturer RENAULT and I'll be driving my MEGANE for a long time! Another request from me: Could you please create a video where you are explaining the differences in British road traffic in opposite to Austrian road traffic (not just the fact of left-hand traffic), but the main intersection and road traffic rules, the mandatory taxes required to use British roads and to what extent my Austrian driving license (pink, old driving license issued in 2000) is valid in the UK? Thank you in advance and best wishes from Styria, Austria 🇦🇹, Christoph Grail 🤝 I left a subscription!

Theres a lot of variables at the end of the day, but im keen to believe, that in this country due to road layout, a 1.6 vs 1.6 turbo petrol is only going to be better on fuel if more consistent motorway use is a thing, if you live in the sticks with b-roads and roundabouts plus navigating past small towns, then i see a turbo engine being worse on economy just due to the fact that someone navigates through more corners than the average and has the turbo spooling up and down more often in their "luxury shopping cart" when using their car for typical general use. I mean i try to think of it the case when the older folk buy a car and believe it to be better on fuel but then being moderately dissapointed when its getting 35mpg instead of the 36mpg they expected.

@fatihuguz. 4 месяца назад

is the fuel economoy better if you go slow for exmaple is going 10 mph instead of 20 mph or 20 instead of 30 is it more effiecent even though air drag is low at those speeds

@drayke8886 4 месяца назад

I can tell you right now that 10 < 20 < 30mph in fuel economy thanks to transmission. Most of time most efficient is top gear with lowest engine speed possible but it's unhealthy for engine (he could drive that Leon 30mph on 6th at ~1000rpm and have way less than 6l/100km but with check engine some time ahead)

@ConquerDriving 4 месяца назад

It depends on the car. I think both these cars are at their most economical at about 30mph if you could maintain that speed over a long distance. But in town, it's stop start driving and that's very inefficient.

@BReal-10EC 4 месяца назад

The MX5 is front engine, rear drive. That has a higher parasitic loss than front front. Mazda (USA) once said in a press release that they don't tune their cars to gain the (US EPA) MPG tests, they tune them for real world driving. The 1.5L 2011-14 Mazda2 was sold in the US and the EPA MPG estimates were easily beaten by owners driving normally.

@blacktemplar7102 4 месяца назад

the big Problem is when you dont drive it eco a turbo needs 3-4 times more fuel than in normal when you drive sporty you will see a far bigger different. target of downsizing is to have low consumption when driving economical with the possiblility to speed up fast when necessary in exceptional or emergency sittuation (without taking the economy into account)

@@flolin8766 It's not. Your engine needs some time to be fully lubricated, longer during winter. If you rev with cold oil you may get metal to metal contact in the engine=sooner engine failure.

The Seat Leon becomes more expensive in the long run. When turbocharger fails then turbo repair/replacement costs will be expensive, in some cases if the broken turbo has leaked too much oil into exhaust system, you probably also have to replace catalytic converter.

I've done 19,000 hours in the Leon and it's still on the original turbo. Think how many years it would take to do 19,000 hours if you were to drive 1 hour a day.

@DjNikGnashers 4 месяца назад

The cars are geared completely differently, as they are for different end tasks. MX5 is geared for acceleration, to make up for it's lack of power (184ps is not a lot these days for a 'sports car'). It is a bit lighter though which is definately going to help (and maybe more aerodynamic too). I'd assume the Seat has longer gearing. FWIW, my last car, a tuned M140i, weighed 1480Kg, had 455bhp/643nm, and I could get an indicated 42+mpg on a run. Pretty good for a fairly heavy, quite powerful, tuned hot hatch. I now have an OG M2, and even though it is less powerful (standard power 370bhp), and weighs only slightly more at 1520Kg, it uses a lot more fuel. I didn't buy it for it's economy though, and I really couldn't care. Interesting video though, and 49mpg from the MX5 is probably better than I expected. The Seat seems pretty good considering it's done over 200k miles 🙂

@Rawmon94 4 месяца назад

i dont think it has anything to do with drag coefficient, urban and 70mph difference is roughly the same on both cars. when air resistance would be a factor in this example i think you would suspect a larger delta between urban and 70mph. i suspect the fact that the engine technology is newer is the biggest factor, then weight, then other resistances

@paultasker7788 4 месяца назад

Mazda is proud of it's right sizing and larger but economical engines without turbos. In the real world similar. Downside is you need to rev more to get the performance but in an MX5 thats a good thing especially with that gearchange. Less so in a hatchback.

Interesting. I've always compared my MR2 1.8 NAs fuel economy to my dad's 1.6 Turbo Tucson. My car is only 2-3 mpg better in town, but 5-6 better on main roads. Interestingly my Celica with the same engine basically matched his economy despite not being much heavier than the MR2, and being far more aerodynamic. The only difference I can think of that'd do that is the gear ratios - the MR2 sits about 300rpm lower at 70. I wonder if weight distribution can effect economy...?

@ConquerDriving 4 месяца назад

At a higher cruising speed it's the frontal area and drag coefficiency that has a big affect on fuel economy.

@ymirfritz9989 4 месяца назад

Bit of an apples to oranges comparison, different cars (+weights), very different engine designs, different gearboxes and final drive ratios, different drag co-efficients and probably different tyres...

This reference about the rowing machine is not true. Damper setting on 1 is for explosive rowers who don't make a lot rows per minute, but each row is explosive and powerful. Damper setting on ten gives a lot resistance and therefore the rower needs to make more RPM by putting less power in each row.

6:15 "I'm not going to drive especially economically" Granted... I believe it's just as hard for you as for me to NOT drive in an economical manner 🤣So I bet this is more economical than "average Joe" anyway... Yet another great test, and your attention to details to keep tests as fair as possible is amazing! Keep it coming 👌 NEDC combined figures looks to be Mazda 6.9 l/100km vs Seat 5.2 l/100km. A massive 25% lower for Seat! I would assume that's a bit much, but for sure I expected the downsized engine to come out on top... You mention the Mazda is lighter. +/- 100kg really shouldn't affect consumption, especially at steady speed. As far as I can find, MX5 CD is 0.36 and Seat is 0.32, but with a bigger frontal area... One can only conclude that Mazda know a thing or two how to make engines I guess..? And the NEDC/WLTP tests isn't worth much when concidering your choice of cars..?
