What Car? says...
Lexus received plenty of criticism back in 2013 when it decided to buck the trend and launch the third-generation IS with a line up of petrol-only engines. Yet, with the future of diesel increasingly in doubt, that decision is starting to look rather inspired.
With only one engine available, the line-up couldn’t be more straightforward. Like most of the Lexus range, you’ll find a petrol engine under the bonnet that’s boosted by an electric motor. This should appeal to company car and private buyers who are looking for a left-field diesel alternative.
