How Tesla saved Honda

Interesting and nuanced video.  Net is, as I see it, typical stupid government regulations, set to support corporate sponsored objectives, failing to deliver the results they are seeking to achieve.  Just like 'dieselgate'.

Simple solution equates to a carbon tax - simply tax fuel more.  Then people can choose between an Jazz or a Porsche and see which one delivers.  It is real efficiency that counts, not government meddling.

Just for the record, the actual consumption and CO2 emissions of our Jazz according to Spritmonitor:

Consumption:           4,57 l/100km
CO2 emission:          106 g/km

A comparison with a popular comparable car, the VW Polo DSG:

Consumption:           5,97 l/100km
CO2 emission:          139 g/km

Mine  never emits jazz.  I have other musical tastes.

Hi, I probably don't understand everything with translations,
but I can't understand a thing,
the machine is homologated as EURO 6, so it means that it complies with that legislation,
why shouldn't it be regular?
(Sorry for the mistakes I went out Google translate)

The video is saying Honda could have been fined 100m euros if it hadn't combined it's CO2 figures with Teslas. It has come out badly because plug-in hybrids are deemed to be rated typically at about 65 against the target of 95 thus lowering the average for the whole brand, but Honda doesn't make any. In practice they're not that good as people often forget to charge them and drive on petrol carrying the heavy batteries around. Also Honda has hardly sold any 'E' cars so that doesn't help either. The Jazz is rated over 100 for CO2 so it is above the EU target.

Yes, I see,
but when you put the probe in the exhaust pipe and measure the CO2 values these must comply with the EURO 6 standards,
otherwise what is the meaning of the regulations?

Yes, it’s a shame the Jazz is so high for CO2 at over 100g.

My old model Yaris hybrid was only around 80g and they did a special edition that was under 75g by removing equipment- so it had free congestion charging zone travel.

[Jazzik]

...and now the harsh reality...
Our previous car was a Toyota Yaris Hybrid. Actual measured consumption and CO2 emissions (Spritmonitor):

Consumption: 4,88 l/100km   
CO2 emission: 114 g/km   


Our Jazz (also Spritmonitor):

Consumption: 4,55 l/100km   
CO2 emission: 106 g/km   

Identical use and driving style... How is it possible that emissions 'on paper' give a completely different outcome than in practice?

Like most car related controls they are formulated via lobbyists to EU & govt neither of whom drive or own their own cars then tested in labs under strict conditions.Best to have pre 1973 car running on sugar cane or even log if you travel high mileage.

For me the interesting thing in this video was how major car manufacturers like Ford got round the EU regulations with plug in hybrids. In the U.K. these cars enjoy very low benefit in kind tax if you are a company car driver. But as previous poster has said, how many bother to plug them in, particularly if they don’t pay for their own fuel?

What Car? magazine did an article recently listing every manufacturer most frugal car and its mpg. Some of these plug in hybrids were quoted as 150mpg or more. In reality the vast majority won’t achieve that and will operate entirely in petrol mode less efficiently than a normal hybrid.

I had a plug in hybrid Volvo XC90 loan car once.

When I picked it up the battery was empty so it was just running on the petrol engine.

Steady 70mph cruising was giving me…24mpg!

The target that Honda would have missed was for the average of all cars sold that year rather than a particular model

The probable answer is that the older Yaris numbers used less challenging NEDC test procedure the whereas the Mk 4 Jazz numbers use the more challenging WLTP test cycle. I suspect that many manufacturers program their vehicles to give the optimum test results whereas Honda aim for the best real life performance (but forgot about winter). I'm sure that getting the Mk 4 Jazz below 100g/km CO2 could be done.

[Kremmen]

If you use Spritmonitor, each time you enter fuelling it works out your actual CO2 wh8ch is useful.

In my entries Hondas figure is quite accurate but I've only got winter figures at the moment.
