Soft perforated leather trims the seats, which are 10-way power-adjustable for the driver and front passenger. The GS 450h features matte bamboo trim and comes standard with heated and ventilated front seats, a heated steering wheel, power rear sunshade and a high-intensity interior heater. Deeply scalloped rear seats provide excellent support and generous legroom.
“Climate control” gets new meaning in the GS 450h. A first-in-class technology, the energy-saving S-Flow automatic climate control system detects if there is a front passenger and directs airflow only to the occupied front seat or seats. The Climate Concierge, meanwhile, enables personalized climate settings. The system automatically monitors the temperature of three separate climate zones and adjusts not only the fans, but also the temperature of the seats and steering wheel according to preset preferences. Each zone will achieve its pre-set level of comfort as quickly as possible.
A unique touch in all GS models, and certainly a reflection of Lexus luxury values, the analog clock is carved from a single ingot of aluminum for a smooth consistent look and uses LED indicators.
The Lexus GS 450h’s new multimedia system provides a multitude of capabilities and also offers the Navigation upgrade. The Remote Touch controller with one-push confirmation is standard and enables smooth, intuitive control of climate, audio, phone, optional navigation and more. A standard rear back-up camera adds security and convenience.
The new standard Display Audio includes HD Radio, Bluetooth audio, automatic phone book transfer, a vehicle information display and complimentary traffic and weather data provided via HD Radio. If a favorite song comes on the radio while you’re busy with something else, like waiting at a bank drive-through, use the cache radio feature to pause it for up to 20-minutes and then listen later.
In addition, the Navigation system can help guide you to your destination more efficiently with up to date and predictive traffic information, including detour preview, ETA calculation and low-fuel coordination with available fuel stations. Navigation also includes the Lexus Enform App Suite and features 3D and bird’s eye map views, plus 3D building views.
Sirii Eyes Free Mode, which the GS 450h gained for 2014, is compatible with the iPhone 4Sand iPhone 5 models forward and puts select Apple’s Siri technology at your service. Siri lets you call contacts, select and play music from iTunes, get turn-by-turn navigation through Siri and Apple maps, and much more.
The hybrid powertrain combines the output of an Atkinson cycle 3.5-liter V6 engine with a water-cooled permanent magnet electric motor through a planetary-type continuously variable transmission. Independently or in parallel as needed, the gas engine and electric motor drive the rear wheels. The nickel-metal hydride battery pack uses a stacked design to optimize trunk space.
Tuning the GS 450h’s ride and response is as easy as turning a dial with the Lexus Drive Mode selector featuring five modes. Normal mode offers a balance of efficiency and performance response that’s ideal for everyday usage and yields the smoothest driving experience. ECO mode prioritizes energy conservation through settings to throttle mapping, seat heating and climate control systems. When driving in ECO mode, instrument meter lighting changes to blue. The EV mode allows the vehicle to be driven short distances, under certain conditions, using only the electric motor.
SPORT mode transforms the car’s personality, with the powertrain control unit (PCU) boosting electric motor drive voltage to a maximum 650V versus a maximum of 500V in ECO mode under normal driving conditions. Sport mode also sharpens throttle response and mimicsthe stepped shifting of an eight-speed automatic transmission. Appropriately, instrument meter lighting changes to red when driving in SPORT S mode.
Selecting SPORT S+ mode also engages a sport setting for the Adaptive Variable Suspension (AVS), electric power steering systemand Vehicle Dynamic Integrated Management (VDIM). The sporting edge does not sacrifice renowned Lexus smoothness and comfort. (0 to 60 in 5.6 Seconds)
