Lexus is working on an aggressive new-product roll-out right now. It already unveiled all-new generations of the GS and ES sedans and revised versions of the LX and RX SUVs. Next up? The LS flagship sedan, and our spy shooter caught a camo-wrapped one out testing. Despite the heavy camouflage, we have a reasonably clear look at the shape and front fascia of the next LS. Lexus' new spindle grille is quite prominent, and seems to dominate the LS’ front fascia. The grille is flanked on either side by what look to be LED headlights, not dissimilar to those available on the current LS 600hL. The headlights are pushed out to the edges of the car and look to have the brand's trademark L-shaped LED running lights below them. In fact, the front visage looks suspiciously close to a shady teaser shown by Lexus in a video describing its new spindle grille. If that image is, in fact, the new LS, we can expect to see a larger upper grille, a chrome outline to the spindle, and cheese-grater-esque metal detailing in the headlights. The rest of the next Lexus LS looks to be taking a more evolutionary tack – from what we can see, both the profile and rear look to be slimmed-down versions of the current car's design, though without losing any of the 2012 model's mass. Don't be surprised to see taillights and a greenhouse similar to those on the 2013 GS and ES sedans. The interior will probably be cleaned up as well, and to use the same oversized infotainment screen and mouse-like controller as the GS, ES, and RX. According to our spy shooter, the new LS will ride on an overhauled version of the current car's platform and maintain its V-8 powerplants. Currently, the LS uses a 4.6-liter V-8 rated at 380 hp and 367 lb-ft of torque mated to an eight-speed automatic. Expect to see the V-8 carry over, but a new hybrid model will eschew the LS 600hL's attempt at V-12-like performance for a focus on efficiency and drumming up more sales than the current $113,635 car. (Base price listed includes destination.) Expect to see the new LS revealed some time within the next six to 12 months and for it to go on sale for the 2014 model year. Until then, check out the spy shots below.
