Pros: As you can see the new GS is available in a number of packages. With gas prices rising, Lexus has no plans for an 8-cylinder in the redesign GS. The 6-cylinder GS is extremely powerful and adequate for this vehicle. With its current bold, high-quality seamless interior, athletic styling and its retuned suspension system, which offers a variety of driving modes, it’s quite obvious that the Lexus GS is making strides in becoming a true driver-oriented, performance luxury vehicle. This is Lexus’ first vehicle that truly can compete with the likes of Audi and BMW, as it relates to the driving experience.

The 2013 GS offers more than just an uneventful luxury ride as has been the case with most of the brand’s line up, until now. So with this midsize Lexus, the engineers have been able to incorporate all of the high-tech luxury amenities we’ve come to expect from the luxury brand, while mixing it up with a near German-like ride. We especially found this to be the case, as it relates to the driving dynamics, when we put the GS hybrid on the test track in Vegas. In fact, we’ve never been behind the wheel of a hybrid -until now – that we actually considered both spirited and fun-to-drive.

Also Lexus offers a variety of ways for the driver to operate the audio, nav and climate control. The GS New Remote Touch computer-like mouse pad allows the user to operate the aforementioned features. The huge screen menu allows the user to pull-up multiple functions like the radio and nav system simultaneously. Besides using the mouse pad, the driver can utilize the standard controls to change stations or the like and the radio controls.

Yes, this Lexus does almost everything for you but drive by itself. We expect the 2013 GS to be a game changer for the brand and the midsize luxury segment, just as it was when it first hit the market in 1991 with its Italian-style design.

Cons: There’s not much to dislike about the new GS. Our quirks were minor. While a number of automakers are offering oversize sunroofs, Lexus is still offering a standard size roof. Where is the panoramic roof or dual panel roofs? Both Hyundai and Kia offer this feature in their non -premium midsize vehicles.

Also the GS with the FS Package we reviewed for the past week was loaded-up with almost every perceived high-tech safety feature. It had everything from a radar cruise control to a lane keep assist warning system, which warned the driver when they were crossing outside of the car’s lane.  However, the vehicle we reviewed lacked the available blinds-spot technology system, which offers visual and audible alerts to the driver of objects in its blind-spot before changing lanes. Just like the back-up camera, blind-spot should be standard on this premium class vehicle, as opposed to a $500 option.

Competition: Audi’s A6, BMW’s 5-Series, Chrysler 300 SRT8 and Infiniti’s M-Series
