We do know that the current LS 450h has a 3.5-liter V6 engine giving an output of around 296hp with a top speed of 149 mph and can accelerate from 0-62mph in 5.9 seconds. Toyota engineers have been working hard to reduce the CO2 emissions and provide a more eco-friendly sedan. The Lexus GS 450h hybrid has been selling at a price tag of £44,615 or USD $71,259 equivalent in the UK. If nothing else, we really hope that Lexus plans to incorporate the styling from the LF-Gh concept. Perhaps this will give the brand the dose of adrenaline it desperately needs.
