Lexus has been a luxury hybrid pioneer, so it comes as little surprise the 2014 IS will be offered with an Atkinson cycle engine. However, a new report is indicating the model will come with something a little unusual - a turbocharger.
According to Auto Motor und Sport, the IS Hybrid will feature a turbocharged 2.5-liter four-cylinder engine with direct injection technology. It could enable the model to consume 4.2 L/100 km (67.2 mpg UK / 56.0 mpg US) and have CO2 emissions of approximately 100 g/km.
If that sounds a little too eco-friendly, the magazine is also reporting the IS will be offered with a turbocharged 2.0-liter engine that develops 200 HP (147 kW).
