Lexus gives IS early updates for 2015

After just a year on the road, Lexus is bringing some modest tech and style upgrades to the 2015 IS. There are no mechanical changes to speak of, but the refinements should spruce things up a little bit.
The only exterior change for the 2015 IS models is the addition of LED foglights, but as they say, it's what's on the inside that counts. All models get an improved radio with Siri Eyes Free voice command for iPhone 4S and 5 users, and the standard backup camera now includes dynamic grid lines. There is also new piano black trim around the instrument panel and window switches, and a Stratus Gray interior color replaces the previous Light Gray. Buyers get a one-year subscription to the Lexus Enform Remote, which allows drivers to use their smartphones to control some aspects of the car, like remotely locking the doors.
Vehicles ordered with the F Sport package get heated and ventilated front seats, and all-wheel-drive F Sport models get a heated steering wheel, as well. The warmed wheel is also optional on non-F all-wheel-drive models. It should keep drivers nice and toasty in the winter.

Lexus looking for performance with 600-hp LF-LC?

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.
According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower - very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.
None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.

2015 Lexus GS 450h also getting F Sport treatment

Lexus is making the 2015 model year version of the GS 450h a bit more appealing with the addition of 18-inch, split five-spoke wheels as standard equipment, and the optional F Sport package to really turn things up. The infotainment system is also getting a few, minor tweaks. Lexus has not officially released photos of the GS 450h F Sport, or a car with the updated wheels.
Previously exclusive to the GS 350, the F Sport package sharpens up the GS 450h behind the wheel to make it a bit more engaging. Ticking that box sharpens the adaptive suspension, especially in Sport S+ mode, and it adds 19-inch wheels with larger front brakes and high-friction pads, as well. If buyers want to go even further, the Lexus Dynamic Handling system is also available to add active rear steering, Lexus spokesperson Bill Kwong told Autoblog. The powertrain is left alone, though, and its hybrid-assisted 3.5-liter V6 producing 338 total system horsepower still returns 29 miles per gallon city, 34 mpg highway and 31 mpg combined.
The F Sport package also adds a mesh grille and new front bumper and, at the back end, buyers get a rear lip spoiler and revised lower valence panel. Inside, there's a sport driver's seat with 16-way power adjustability, a black headliner and added aluminum trim.
