2025 BYD Sealion 7 Summary

Looking across BYD's line-up, you'd think you were reading the attractions for the local aquarium! And now the Sealion 7 has entered the splash zone, or more accurately, the most popular car segment - the mid-size SUV.

It fights for pole position against the long-running electric favourite, the Tesla Model Y but newcomer Cupra Tavascan also offers some sporty competition.

For this review we're testing the flagship Performance grade to see whether or not it offers family-friendly fun.

2025 Smart 3 Summary

Smart is back.

Not with the classic ForTwo two-seater city car, oddball four-seater ForFour hatch or dinky Roadster targa top. Those were yesterday’s cars.

Today, Smart – as a 50/50 joint-venture between Germany’s Mercedes-Benz (the brand’s originator) and China’s Geely – is all about SUVs. Electric SUVs.

The boxy #1 (pronounced “hashtag-one”) is a small SUV and the sleeker #3 is the coupe-esque performance crossover version. Both are made in China and use Geely technologies.

We take a long, hard look at the range-topping #3 Brabus, the speediest, sexiest and exxiest of the lot. Let’s go.
