In Korea, the Hyundai Inster goes by another name: Casper Electric (캐스퍼 일렉트릭). Hyundai sells it through its Casper online store, and that’s the name you’ll see in Korean reviews and listings.
Our Korean vs international Hyundai and Kia model name lookup table shows how to confirm the two are the same car using owner’s manual codes. Here, we look at how the versions differ from market to market.
All figures below come from Hyundai’s official pages in Korea, the UK and Australia, checked in October 2026. Where a page doesn’t say something, we’ve left it out.
The short answer
The batteries, motor outputs and body dimensions line up across all three markets. What differs is the trim names, which versions each market spells out in detail, and the official range numbers.
Korea’s range figures are noticeably lower than the UK and Australian ones for the same battery and wheels. They’re certified under a different system, so the two sets of numbers shouldn’t be compared directly.
Size: practically identical
Hyundai UK’s model page doesn’t list dimensions, so this table compares Korea and Australia only.
| Korea (Casper Electric) | Australia (Inster) | |
|---|---|---|
| Length | 3,825 mm (Cross: 3,845 mm) | 3,825 mm (Cross: 3,845 mm) |
| Width | 1,610 mm | 1,610 mm |
| Height | 1,575 mm (1,610 mm with roof rack) | 1,610 mm (including roof rails) |
| Wheelbase | 2,580 mm | 2,580 mm |
The only difference is how height is quoted. Korea gives the figure without a roof rack first, while the Australian spec sheet includes the roof rails.
Batteries and power by market
All three markets list the same two batteries, 42 kWh and 49 kWh, with matching motor outputs. Torque is 147 Nm wherever it’s listed.
| Battery | Power | Korea trims | UK (as listed) | Australia (spec sheet) |
|---|---|---|---|---|
| 42 kWh | 71.1 kW (UK: 71 kW / 97 PS) | Standard, 15″ wheels | Standard range, 15″ wheels | INSTER |
| 49 kWh | 84.5 kW (UK: 85 kW / 115 PS) | Long-range (15″ or 17″) and Cross (17″) | Long range, 15″ or 17″ wheels | INSTER and INSTER Cross |
Korea is the most explicit. Its spec page names a trim for each battery and wheel combination and gives a range figure for each one.
Australia’s spec sheet marks both batteries as available on the regular INSTER and only the 49 kWh battery on the Cross. Its detailed figures, though, cover just two versions: the 42 kWh Standard Range on 15″ wheels and the 49 kWh Cross on 17″ wheels.
Why the range numbers don’t match
The UK and Australia quote WLTP figures. Korea quotes its own government-certified figures, the ones on the Casper Electric spec page.
| Battery / wheels | Korea (Korean certification) | UK (WLTP) | Australia (WLTP) |
|---|---|---|---|
| 42 kWh, 15″ | 278 km (173 mi) | 203 mi (327 km) | 327 km (203 mi) |
| 49 kWh, 15″ | 315 km (196 mi) | 229 mi (369 km) | — |
| 49 kWh, 17″ | 295 km (183 mi) | 223 mi (359 km) | — |
| 49 kWh Cross, 17″ | 285 km (177 mi) | — | 360 km (224 mi), with sunroof |
| 49 kWh Cross with roof basket | 248 km (154 mi) | — | — |
Figures in brackets are our own conversions (1 mile = 1.609344 km), rounded to the nearest whole number. A dash means that market’s page doesn’t give a separate figure for that setup.
The two WLTP markets agree. The 42 kWh car is rated at 203 miles in the UK and 327 km in Australia, the same figure once converted. Korea rates the same battery and wheels at 278 km, 49 km lower by our subtraction.
Hyundai’s pages don’t explain the gap. Hyundai Australia’s own disclaimer notes that WLTP figures are only meant for comparing cars tested under the same procedure. The practical rule: compare Korean figures with Korean figures, and WLTP with WLTP.
Both the Korean and Australian pages also warn that real-world range varies. Korea singles out cold weather, while Australia lists driving style, climate control and conditions.
Trim names in each market
Trim ladders don’t map one-to-one, so match cars across markets by battery and wheel size, not trim name.
- Korea: 기본형 (Standard), 항속형 (Long-range) and 크로스 (Cross), with our translations in brackets. The Cross also gets a separate range figure with its roof basket fitted.
- UK: INSTER 01, INSTER 02 and INSTER Cross. The 02 adds 17″ wheels, and the Cross adds the Cross design package and a glass sunroof, among other features.
- Australia: INSTER and INSTER Cross.
The Inster wasn’t on Hyundai’s US lineup when we checked in October 2026, so there’s no US version to compare.
Checking prices
We haven’t listed prices because they change often, and Korean EV prices also depend on subsidies that vary by region and year. Each market’s official page is the place to check:
- Korea: Hyundai Casper online store (Korean only). The spec page has a price list download.
- UK: Hyundai UK Inster page, which shows starting prices by trim.
- Australia: Hyundai Australia Inster page, through its Build & Price tool.
Looking for this car in Korea
If you live in Korea or read Korean owner forums, search for 캐스퍼 일렉트릭 or “Casper Electric”. Searching “Inster” is far less useful in Korean results.
One more trap: plain 캐스퍼 (Casper) is the gas-powered model, a separate car with its own spec tab on the Korean site. Check for “일렉트릭” (Electric) in the name before you trust a review or listing.
