Automotive Review

The continuously variable transmission is the Lexus GS 450h ( CVT ) offers a Sport mode upgrade for 2014 . Lexus says it has been optimized for feature eight steps instead of six to make it feel more like a GS 350 eight - speed automatic . Apple iPhone integration is also improved by the addition of Siri voice control function Eyes free . Other additions this year include a full color readout for the optional head - up display , rear cross traffic for the blind-spot monitoring system is optional and optional power trunk opener . Night vision system has been discontinued .

While the typical hybrid car is all about maximizing mpg , luxury hybrid has a more complicated mission . They serve affluent buyers who also want a quick acceleration , responsive handling and elegant interior loaded with amenities . As a result , high-end green machine is often quite fun to drive , but the fuel efficiency gains , their counterparts conventional gasoline - which is often quite simple . 2014 Lexus GS 450h is unique because it offers features and performance expected of a luxury sedan medium while delivering great fuel economy figures that many hybrid buyers expect .

Powering the 2014 Lexus GS 450h is a hybrid powertrain that combines a gasoline engine 3.5-liter V6 , two motors / generators and battery electric rod - mounted to provide a total system output of 338 horsepower . Of course , the real attraction here is the impressive fuel economy of the GS 450h . With a combined EPA rating of 31 mpg , the Lexus shines as one of the most fuel-efficient models in the luxury sedan segment .

In the best tradition of the Lexus GS 350H which had characterized the interior is made of fine soft leather and rich wood and aluminum trim . Matches of this caliber luxury sport sedan and cosseting seats firmly in the same size , and only limited by the power adjustment level you choose . At the rear , two average-sized adults should be quite comfortable , although the BMW 5 Series is roomier silent .

Touch multimedia remote controller GS 350 is more problematic . Its small , mouselike device adjacent to the gear selector makes sense conceptually , but the shaky cursor control and precise , and make audio or navigation options even more difficult when you re traveling . Further complicating the process is the lack of a physical system "back" button , and the fact that all the icons are the same color . That said , we do like the impressive large-screen 12 - inch is equipped with the optional navigation system and the optional Mark Levinson audio system , which sounds fantastic .
