Fun Facts First

A first for BYD hereThis is BYD's first plug-in hybrid sedan in Singapore. Before this, their plug-in hybrid offering was an SUV.
KL and back, with leftoversWith around 1,300km of combined range on paper, a return trip to KL is theoretically possible without visiting a petrol kiosk on either side of the border.
Not just a Seal 6 with an engineThe DM-i gets its own front bumper and tail light design, so it doesn't look exactly like the regular Seal 6.
105km of pure electricThat's more than enough for most of our weekday routines. Think office, school run and an NTUC stop, with plenty of charge to spare.

Introduction

BYD has been busy filling every gap in its Singapore line-up, and the Seal 6 DM-i is its answer to people who like the idea of an EV but are not quite ready to give up the petrol tank. It's the brand's first plug-in hybrid sedan here, and we spent time with the Premium version to see whether it makes sense for everyday Singapore life.

So what does DM-i actually mean? It stands for Dual Mode Intelligence (BYD also calls it "Super Hybrid"). In plain English, the car tries to drive on electricity as much as possible. The 1.5-litre petrol engine mostly works in the background, charging the battery and helping out at higher speeds or when the battery runs low. You can also switch between EV and HEV modes yourself, so you decide whether to save the battery for later or use it up first.

The short version: it's an electric car for your daily drive and a hybrid for your long drives. One car, two personalities, zero range anxiety.

Exterior Design

First impression? Sleek. The Seal 6 DM-i has a clean, flowing shape that looks more expensive than it is. Up front, the grille has a wave-like pattern, a nod to BYD's ocean theme, and the lower grille gets chrome bits and body-coloured trim that dress it up nicely without going overboard.

If you're wondering how to tell it apart from the regular Seal 6, look at the front bumper and the tail lights. Both are designed differently on the DM-i, so it has its own identity in the car park.

Interior Review

Step inside and things are pretty basic and simple. That's not necessarily a bad thing. It's a no-frills cabin that gets on with the job. You still get a leather-wrapped dashboard, ambient lighting for the night drives and a panoramic glass roof that makes the cabin feel brighter.

Infotainment & Sound

The 12.8-inch infotainment screen is easy to use, and the 8.8-inch driver's display gives you what you need at a glance. The best part for us: pairing Android Auto and Apple CarPlay was easy, so you're streaming your playlist before you've even left the HDB car park.

The Button We Have Feelings About

Here's our main gripe. The engine start/stop button sits in a row with other buttons, including the EV/HEV mode switch and the hazard lights. We felt it should live closer to the steering wheel, because it's very easy to press the wrong one. Nobody wants to switch on the hazards when they just wanted to start the car.

Seats & Comfort

Comfort is one of its strong points for the price. It's an easy car to settle into, and nothing about it feels like hard work on a daily drive.

Rear Passenger Space

Legroom at the back is okay, but headroom is on the low side, so taller passengers may notice it. Two adults fit just nice. Three adults can work, depending on who they are and how far you're going. A short makan run, sure. A long drive up north, maybe draw lots.

Rear passengers aren't forgotten though. There are rear aircon vents to keep things cool in our weather, plus USB-C ports so everyone can keep their phones alive on the way to JB.

Boot Space

The boot gives you 491 litres, which is a decent size for a sedan. Weekly groceries, a couple of luggage bags for a weekend away or the golf set should all go in without a fight.

Driving Experience

Ride & Handling

The Seal 6 DM-i is easy to handle and nothing too sophisticated. The steering is light, which makes tight car parks and multi-storey ramps a breeze. There is a small amount of body roll, which is expected for a car like this. You will feel some vibration going over speed bumps and humps though, so take those condo humps slowly.

Light steering and easy handling make it a relaxed daily driver.

With 219bhp and 260Nm from the combined system, there's enough go for merging onto the expressway without drama.

Refinement

Road noise is average. You can hear it quite clearly. At higher speeds, a bit more noise gets into the cabin, but it's generally okay. When the engine works harder at higher revs, it can get slightly louder too. Around town in EV mode, though, it's the quiet you'd expect from an electric car.

Range & Charging

On paper, the 19kWh battery gives you about 105km of electric range, and the total combined range is around 1,300km. For most of us, that means weekdays could be mostly electric, with the petrol engine saved for long trips across the Causeway.

On paper vs real life: these are claimed figures. Your real-world range will depend on how you drive, the traffic and how hard the aircon is working in our weather.

Is It Right for You?

Buy it if

  • You want to drive mostly electric but keep petrol as backup
  • You drive into Malaysia often and hate planning charging stops
  • You want comfort and long range at a decent price
  • You prefer simple, easy-to-use tech

Think twice if

  • You regularly carry three tall adults at the back
  • A quiet cabin at expressway speeds is high on your list
  • You want a plush, feature-packed interior
Singapore driving tip: if you have a charger at home or nearby, top up regularly and stay in EV mode for daily driving. Switch to HEV mode before a long expressway or Causeway run so you still have battery saved for crawling through the jam at the checkpoint.

What We Like

  • Sleek design with its own front and rear look
  • Long electric and combined range on paper
  • Easy, light-steering drive
  • Painless CarPlay and Android Auto pairing
  • Rear aircon vents and USB-C ports for back-seat passengers
  • Comfort and range for a decent price

Could Be Better

  • Move the start/stop button away from the hazard switch
  • More rear headroom
  • Better insulation from road noise at speed
  • Smoother over speed bumps

Verdict

The BYD Seal 6 DM-i Premium isn't trying to wow you with a fancy cabin or sporty thrills. It's a sleek, easy-going sedan that lets you drive on electricity most of the time and still go long distances without thinking about chargers.

It has its quirks. The start button placement needs a rethink, the rear headroom is tight for taller folks, and you'll hear the road at higher speeds. But for a decently priced car with this much comfort and range, those are things most owners will learn to live with. If you want an EV-like daily drive with a safety net, this one deserves a test drive.
