100 KMH highway real world BYD Sealion 6 Fuel Test over 400km (AWD/Premium) BYD SONG PLUS DM-i

Summary

In this video, the car owner tests the fuel consumption and efficiency of their hybrid vehicle. They examine the accuracy of the car's fuel range indicators, noting that the remaining range isn't always linear. Through real-world driving, they discover that driving at lower speeds (100 km/h) improves fuel efficiency, and they confirm the car’s hybrid battery charges effectively at high speeds. Additionally, the driver highlights the impact of Eco vs. Sport mode and shares insights into the car’s overall fuel performance, offering viewers valuable information on hybrid vehicle usage.

Takeaways

• 😀 The user did not fuel up the car initially after a previous trip, which led to a follow-up test to verify fuel consumption accuracy.
• 😀 The car displayed 291 km of remaining range with 29.1% of the fuel remaining, which was used to estimate fuel consumption accuracy during the test.
• 😀 The car's fuel tank is 60 liters, and the user estimates that with 25.1% fuel remaining, about 45 liters should be needed to fill it up.
• 😀 The user compares the car's digital range estimate (1000 km) with the real-world range, noting it is inaccurate and more realistic to expect around 800 km with a full tank and battery.
• 😀 The car's fuel consumption showed 40.2 liters used, yet the fuel remaining estimate read as if it had a 1000 km range, which the user believes is percentage-based and not kilometers-driven-based.
• 😀 The user also noted a potential issue where the car’s fuel range display doesn’t update accurately as the fuel tank nears empty, getting progressively worse.
• 😀 A full tank of 42 liters allowed the user to cover a distance of 554 km at speeds mostly around 110 km/h, which is better than expected for highway driving.
• 😀 The user notes that the car's range estimation is sometimes imprecise, especially when moving between eco and sport modes, but this didn't significantly impact the fuel test results.
• 😀 The user reports that when driving at a steady speed of 100 km/h, the fuel efficiency improved, with the consumption dropping to about 6 liters per 100 km compared to 7-8 liters when driving faster.
• 😀 A common misconception was addressed where it was believed the alternator couldn’t charge the battery at high speeds with a low charge; the user verified the system can indeed charge the battery even at 115 km/h, and it reached 70% from a low charge.

Q & A

What was the purpose of the follow-up video mentioned in the script?

The follow-up video aimed to verify whether the fuel consumption figures were accurate and if the car's fuel gauge and range estimate were reliable.

What is the theory the speaker is testing regarding fuel percentage and range?

The speaker theorizes that the fuel gauge in the car is based on a percentage rather than actual kilometers, as the range decreases incrementally by one kilometer at a time when the fuel is low.

How much fuel did the speaker expect to put into the car based on their calculations?

The speaker expected to put around 45 liters into the car's 60-liter tank, based on the remaining fuel percentage (around 25.1%).

What did the speaker observe about the fuel economy when driving at different speeds?

The speaker observed that the fuel economy improved when driving at 100 km/h as opposed to 110-115 km/h, noting that the economy dropped to around 6L per 100 km on the highway.

Why did the speaker mention being in 'sports mode' at some point during the test?

The speaker noted being in 'sports mode' during part of the test, even though they didn’t intend for it to affect the results, and felt the need to clarify it as some viewers might question the impact on fuel efficiency.

What did the speaker find regarding the car's battery charging behavior at high speeds?

The speaker found that the car's generator could charge the battery even when it was very low, maintaining or increasing the battery level while driving at high speeds (115 km/h).

What did the speaker conclude about the accuracy of the car's fuel range estimate?

The speaker concluded that the car's fuel range estimate (1000 km at full capacity) might be inflated, and that the real-world range is likely closer to 800 km with a full tank and a full electric charge.

How much fuel did the speaker record using during the trip, and how does it compare to the car's estimated consumption?

The speaker used 42.1 liters of fuel, which they found to be a higher than expected consumption rate compared to the car's estimate of 40.2 liters, and this discrepancy seemed to be related to how the fuel gauge measures usage.

How did the speaker track fuel usage during the trip?

The speaker tracked fuel usage by checking the car's energy consumption and the trip meter, calculating how much fuel was used since the last reset, and cross-referencing that with the remaining fuel estimate on the dashboard.

What did the speaker mention about the fuel efficiency during the trip from the Logic Center to New South Wales?

During the trip, the speaker drove 200 km on cruise control at 100 km/h, achieving a fuel consumption rate of approximately 6L per 100 km, which was better than their nominal fuel economy of 7-8L per 100 km.
