Volkswagen Golf GTE85 MORE: Hybrid multifuel SYCOMOREEN

[Remundo]

no problem come on, kisses!

I ramble a bit, but my GTE for me is not really optimal. I would prefer a predominantly electric car with a thermal range extender, 30 or 40 hp would be sufficient. In normal driving, a car like the Golf consumes an average of 15 kWh / 100 km at 70 km / h on average, which makes a smoothed power requirement of 15 kWh / 100 km x 70 km / h = 10,5 kW, only 14 ch.

that would not prevent having high peak powers (eg 100 kW / 140 hp) when digging into the batteries, as long as they have a sufficient level of charge (eg> 20%)

This generator set should be suitable for biofuel (E85 for example, but also biodiesel or biogas).
Electricity should be from renewable sources.

In fact the biggest project is not the vehicle, it is the energy mix!

As a summer interlude, I offer 2 videos on the beet cultivation in France and Switzerland

I was late in my updates, here's heavy:

1) the 15ème and 16ème 100-hour driving cycles in GTE85 +

2) the fifth full of 40L of E85 having allowed to exceed 2000 km without refueling


In summary, Over these last 200 hours of driving "on average":

* 8800 km traveled

* 2L / 100 km from E85 and 10 kWh / 100 km power

* the CO2 emissions are divided by 10 about

* 430 € were saved compared to a Golf7 1,4 TSI petrol.


I offer you the pastis:





there is a lot to understand in this picture :-)

I just received an Advertising SMS from my VW dealership.

It is about destocking on Golf 7, in particular GTE, following the arrival of Golf 8

I think the operation is not limited to Arvernes.

So notice to those looking for a new GTE at a reasonable price... Frankly the G7 GTE does 95% of what the Golf 8 e-hybrid will do. Probably for € 10 less.

The ecological bonus of 2000 € still applies until 31/12. After only 1000 €.

Also to read in the news: the ENERKEM file: thermochemical conversion of organic waste into liquid fuel (methanol, ethanol, kerozene)

News from the Golf GTE85 PLUS

Irony of history or a sign of fate, I'm done my last cycle of 100 hours of driving over 100 hours a few hours before the 12 fateful strokes of midnight yesterday ...

I have traveled 4877 km since the replacement of my HT battery in August 2020, here is the result:



4877 km crossed in 100 hours of driving: 49 km / h average

Fuel consumption in E85: 2.6 L / 100 km
Electricity consumption: 8.9 kWh / 100 km

Note that on this cycle, there were around 60 L of SP95 gasoline and 67L of E85 burnt (respectively at 1,35 € / L and 0.48 € / L), because I can no longer run 100% E85 following the flashing by VW of the engine ECU during repair in August 2020.


Fuel costs: 113.16 € for 2,32 € / 100km
Electricity cost: 1.78 € / 100km

Total: 4,1 € / 100 km

CO2 reduction factor assuming that E85 reduces CO3 emissions by a factor of 2 with an excess consumption of 15%

4877 km x 6L / 100km / (60L + 0.33 * 67L /1.15) = 3,69

We see that despite almost 50% by volume of gasoline, the economic and ecological results remain interesting!

I put you my excel spreadsheet in direct link which includes 17 cycles of 100 hours of driving since the conversion for almost 90 km traveled. For this 17th cycle, in order to harmonize the results, I recalculated the equivalent consumption that I would have had in full E85 (2.8L / 100 km instead of 2.6L / 100km).

Hello Remundo,

Changing the HT battery cost money on fuel economy ??

Some have been taken over by VW

my battery was replaced under warranty.

The video for the months of December 2020 - January 2021 takes a look back at the series hybrid prototype Briggs & Stratton 1980 years

At the dawn of the 1980s, Briggs and Stratton, famous manufacturer of small reliable and robust gasoline engines intended for various vehicles in stationary mode, wishes to diversify by implanting its machines in hybrid cars.

Indeed, the average power to move a car at normal driving speeds is between 10 and 20 kW (approximately 15 HP to 30 HP). We can therefore design a stationary motor of modest power which constantly supplies an electric battery and / or an electric generator, the latter will then be able to provide the ephemeral peaks of power required by driving (up to several hundred horsepower).

And Happy Holidays, despite the context.

Very interesting! I didn't think the concept of hybridization in this style was from those years.
Not sure that it will return, while this solution declined in the form of "range extender", with a very small engine, seems very relevant to me.

Hello econologists,

The new year is often a good time to do some accounting, here is the last batch in GTE85 +; the 18th cycle of 100 hours of driving



I summarize : more than 4800 km traveled at an average of 48 km / h, CO2 reduction by a factor of 6, financial savings: € 230. All details here


The summary of the 18 cycles and their parameters is available: in this Excel spreadsheet

To date, the GTE85 + has accumulated: 1820 hours of testing, 92179 km traveled, € 5230 in fuel savings and around 11575 kg of CO2 which have not been emitted into the atmosphere (based on 6L / 100km - 143.5 gCO2 / km : 13228 kg emitted in fossil fuel and reduction factor 8)

Of these 92000 km, approximately 3/5 were propelled in electric mode: i.e. 55000 km. The cable with EVSE integrated in the socket manufactured by Wattsattitude, charged around 8300 kWh in the Golf GTE battery, ie the annual production of only 9 kWp (80 m²) of photovoltaic panels.
