2023 Lexus LS500 Summary

Surprisingly, for people who would rather be driven than drive themselves, there are quite a few options available in the large luxury sedan market.

While on the whole sedans have fallen from favour, this niche corner of the market continues to let the three-box design thrive.

The options here have changed a bit in the last few years, though, so how does the Lexus flagship, the LS fit into the picture? I drove one around for a week to find out.

2026 Cadillac Optiq Summary

The lonely Cadillac Lyriq finally has some company, with the iconic US brand tripling its range down under with the launch of the much bigger Vistiq (which we've already tested) and this entry-level Optiq, which Cadillac describes as the gateway to its electric family.

It's a medium all-electric SUV with plenty of equipment and – depending on whether you see it as an established premium player or another newcomer brand – pretty sharp pricing.

Cadillac says it has the German big three in its sights with the Optiq, so how does it stack up?

Verdict

The LS500 is the least logical version of the most logical option in the ultimate luxury sedan segment in which logic doesn’t often apply at all.

Take from that what you will, but if it was me being driven around I would definitely be opting for the hybrid version of the LS instead for its smooth electrified driving characteristics and lower operating costs.

Verdict

A taste test, but so far so good for the Cadillac Optiq, which is already my favourite model in the Caddy range. More space than you think meets a lovely cabin experience and a punchy powertrain.
