For the identified Chinese-market versions, the 2027 AION i60 range extender has a longer published battery-only range than the Song Pro DM-i Feichi 301KM grades: 350 km versus 301 km under CLTC. The respective battery capacities are 45.37 kWh and 34.27 kWh. That gives i60 a 49 km rated electric-range advantage and an 11.10 kWh larger stated battery. These are specification differences, not a measured real-world lead or proof of better efficiency. [I60_CFG][SONG_PARAMS]
Compare the range-extender versions with the named Song Pro grades
The relevant AION i60 entries are the 2027 1738 range-extender grades. The BYD entries are the Chinese Song Pro DM-i Feichi 301KM variants shown in the official parameter table. Naming these versions prevents the comparison from mixing an i60 battery-electric model with a Song Pro plug-in hybrid, or substituting an older Song Pro range. [I60_CFG][SONG_PARAMS]
Both vehicles offer battery-powered travel together with a fuel-supported energy system, but their technical implementations should not be assumed identical. The comparison here isolates a particular buying question: how much rated battery-only distance is published for the specified versions? It leaves total range, fuel use and other equipment as separate subjects requiring their own matching information.
The official figures can now be placed in one table
The table retains the same electric-range cycle and separates capacity from distance. The difference column is simple arithmetic from the stated values; it is not a new road-test result.
| Measure | 2027 AION i60 range extender | Song Pro DM-i Feichi 301KM | Difference |
|---|---|---|---|
| CLTC battery-only range | 350 km [I60_CFG] | 301 km [SONG_PARAMS] | i60 +49 km |
| Stated battery capacity | 45.37 kWh [I60_CFG] | 34.27 kWh [SONG_PARAMS] | i60 +11.10 kWh |
| Comparison scope | Identified Chinese-market range-extender grades | Identified Chinese-market 301KM grades | Not all versions of either nameplate |
This is a stronger comparison than a generic statement that one car has more range. A reader can identify the exact versions and reproduce the calculation. If either manufacturer changes a grade or the buyer chooses a different version, the table should be rebuilt from those new columns rather than carried over unchanged.
What the extra electric range can mean for a household
A longer rated battery-only range may provide more flexibility between charging opportunities. For a household with a fixed commuting pattern, that can make the i60 range extender attractive as a vehicle intended to spend a substantial share of ordinary travel using battery energy. The actual interval depends on the journeys, conditions, reserve and charging pattern.
Do not convert the 49 km specification difference into a guaranteed number of extra commuting days. Two drivers can use the same car differently, and the laboratory cycle is not a prediction for every route. The practical question is whether the extra rated capability creates a useful margin for the owner's schedule. That is a legitimate benefit to investigate without promising that the published distance will be reproduced exactly.
A larger battery does not automatically prove greater efficiency
Capacity is the amount of energy stated for the battery; efficiency concerns the energy required for a given amount of travel under defined conditions. The larger i60 pack helps explain why battery capability is central to its proposition, but pack size alone cannot establish an efficiency winner.
It would also be misleading to infer a vehicle's certified consumption by dividing these headline capacities by rated range without checking definitions, usable energy and the applicable test method. For ownership costs, use properly matched consumption data and local electricity and fuel prices. For charging convenience, use the actual charging limits and intervals of each selected grade. These are related decisions, but they should not be collapsed into a single range ratio.
Two range-comparison questions
Can i60's 1,738 km total-range figure be compared with Song Pro's 301 km?
No. The former is a fuel-plus-battery total-range claim, while the latter is battery-only CLTC range for the named Feichi version. The useful comparison above uses battery-only CLTC on both sides. [I60_CFG][SONG_PARAMS]
Does the range advantage settle the purchase?
It settles one clearly defined specification question. The final choice should also consider the current complete price, cabin fit, charging access, local support and the equipment of the selected grades. A buyer may value the extra electric margin differently from another buyer.
The matched comparison conclusion
The 2027 i60 range extender has a verifiable electric-range and battery-capacity advantage over the identified Song Pro DM-i Feichi 301KM variants. That is a concrete reason to consider i60 for a household seeking substantial battery-only capability with fuel-supported flexibility. Keep the 49 km advantage attached to these versions and CLTC, then evaluate its practical value against the household's own journeys. Doing so preserves a useful product strength without exaggerating it into an untested real-world or efficiency claim.
