I Drove a BYD Seal. I Have Feelings About This.

I am not a car journalist. I want to be upfront about this. I am a man from Reading who spent three years convincing his wife to let him buy a Tesla Model 3 and who now evangelises about charging costs at dinner parties until people find reasons to leave. My qualifications to review the BYD Seal are, accordingly, limited. I drove one for a weekend through Berkshire and into Wiltshire, and I have opinions, and I cannot decide whether those opinions are rational or defensive.

Let me give you the numbers first, because numbers are easier than feelings.

The BYD Seal RWD starts at £35,490. The Tesla Model 3 RWD starts at £40,990. That is a £5,500 difference. Over five years, assuming you saved that premium and didn't spend it on anything, at even a modest interest rate you're looking at £6,000+ of meaningful financial advantage before you've factored in the running costs — where the Seal's superior real-world efficiency of approximately 3.8 mi/kWh versus the Model 3's 3.5 mi/kWh extends the gap slightly further.

The 0-62 times are essentially identical. 5.9 seconds vs 5.8 seconds. That is not a meaningful difference in any real-world context, unless you are regularly racing a BYD Seal from a standstill, which would be a very specific situation.

What it was actually like to drive

Good. It was good. That is not a satisfying sentence for me to write, but there it is. The Seal is smooth, quiet, composed on the A4, confident on the M4, and the one-pedal driving mode is well-calibrated. The regenerative braking isn't as immediately adjustable as I'd like — you get it or you don't, basically — but it works. The suspension is slightly softer than the Model 3, which some people will prefer and I have decided I don't, despite the fact that my back is 46 years old and would probably benefit.

The interior is where I have the most complex feelings. It is perfectly adequate. The 15.6-inch rotating touchscreen is genuinely clever and a bit of a showpiece. The materials are fine. And yet.

And yet it smells different. I cannot tell you precisely how it smells different. It smells like a new car, the same way all new cars smell like new cars, but this new car smell is... new car smell in a slightly different key. This is not a rational observation. I am aware of this. My wife, when I raised it, stared at me for a long moment before returning to her book.

What the data actually says

The BYD Seal charges at up to 150kW DC. The Model 3 at up to 170kW. In practice, at the rapid chargers I've used in the Thames Valley, both cars spend most of their time well below their peak rates anyway — real-world conditions, battery temperature, state of charge. The difference is there but unlikely to matter to the vast majority of UK drivers.

BYD is the world's largest EV manufacturer by sales volume. They make their own batteries, their own chips, their own everything. The blade battery in the Seal has a strong safety record and the company stands behind a 6-year/150,000-mile warranty in the UK. The after-sales network is smaller than Tesla's, which is a legitimate concern, but growing.

Autocar gave it four and a half stars. What Car? gave it Car of the Year 2024. Auto Express loved it. Every data point I have access to says this is an excellent car at a price that undercuts the competition significantly.

I have not bought the BYD Seal. I still have the Model 3. I am aware that this makes me exactly the kind of person I mock — somebody who says they want to be data-led and then finds a reason not to be when the data says something inconvenient. The reason I have not bought it is that I have owned the Model 3 for three years, and I like it, and the Supercharger network is very good, and — look. The interior of the BYD smells different, alright? I'm not made of stone.

If you're buying an EV now for the first time, with no loyalty to any ecosystem: the Seal is an extraordinary piece of value engineering. Run the numbers. The numbers are very compelling. I have.
