BYD's Seal and the freshly updated Seal 6 go head‑to‑head as the Chinese EV player tries to turn a promising coupe‑ish saloon into something truly polished. We pit range, tech and driving feel against each other to see if the Seal 6 is a worthwhile upgrade—or just a shinier Seal with a fancier …

Think of the BYD Seal U as the nimble, slightly sharper hatchback that’s happier darting through city streets, while the BYD Seal 6 is the sleeker, longer-legged cruiser built for relaxed motorway miles and extra range. If you want playful agility and everyday practicality go Seal U, but if …

Casalini 550

The Casalini 550 is a compact city runabout that packs surprising practicality into a tiny footprint, making parking a breeze and daily errands almost enjoyable. It won't wow on long highway blasts, but for shopping trips and short commutes it's a clever, affordable alternative to a full-size car — proof that you don't need a giant wallet to get where you need to go.

I'm disappointed; the exterior beauty wears off, the trunk is almost toy-like, the acceleration is weak, and the very basic sound system doesn't do justice to what you expected.

Great car! Comfortable, nice interior space, classy materials, and the wagon’s loading capacity is a major asset.
Combo AC/DC charging socket — in other words, Home/Highway — all-electric range over 100 km.
IT HAS EVERYTHING TO PLEASE!!! AND ABOVE ALL THE PRICE!!!

For the current price (€36,000) the car is an absolute steal!
Unfortunately cars with different equipment levels are being compared here, which is absolutely not acceptable!
The Seal6 comes with every possible extra, for which on the Passat you'd easily have to pay an additional €12,000.

A smart estate, plenty of space for everyday use and extremely economical if you can charge at home now and then. The electronic assist systems are pretty annoying, but can be deactivated before setting off. It needs some software adjustments.
