 OVERVIEW The new 2-mode full hybrid system will be launched in the Yukon Hybrid for 2008. When combined with Active Fuel ManagementTM, it is expected to enable the Yukon Hybrid to deliver a composite fuel economy improvement of 25 percent (based on EPA estimated MPG 15 city/21 highway 4WD for the 2007 Yukon (non-hybrid) with Vortec 5.3L engine). EPA-estimates for Yukon Hybrid not available at the time of printing. | | SELECTED STANDARD FEATURES | Safety and Security • Dual-stage front air bags with Passenger Sensing System1 • Head curtain side-impact air bags1 with rollover sensor • Tire Pressure Monitoring System9 • OnStar 1-year Directions & Connections Plan2 (fleet delete available) • StabiliTrak® stability enhancement system with Proactive Roll Avoidance • PASS-Key III theft-deterrent system • Daytime Running Lamps and automatic lamp control • Rearview Camera System • Tire Pressure Monitoring System Interior • 6-way power heated seats with leather seating surfaces • 2nd-row 60/40 split-folding bench seat • Driver Information Center • 3 auxiliary power outlets • Remote Keyless Entry • Tilt adjustable steering column • AM/FM with CD/MP3, XM® Satellite Radio,3 navigation system11 | Mechanical • Vortec V8 SFI engine LIVC with Active Fuel ManagementTM • Hybrid Propulsion Electric, Parallel, 14v/42v with 120v-2400w outlets • 4-speed automatic strong hybrid transmission • 4-wheel disc antilock brake system Exterior • Lowered 10mm in the front • Aluminum streamlined hood • Dual-port grille with large air intake • Streamlined fascias, running boards and wheel openings • Power, heated mirrors • Lightweight aero-efficient wheels • Aluminum rear liftgate, wiper/washer |  | 2-MODE HYBRID FEATURES The 2-mode is a patented hybrid technology with two modes optimized for city and highway driving. • First mode: At low speed and light loads, the vehicle can operate by electric power or engine power or any combination • Second mode: Primarily for highway speeds providing electric assist and full V8 power when needed. It integrates sophisticated electronic controls, Active Fuel ManagementTM, cam phasing and late-intake valve closure for efficient engine operation • 2-mode system allows for more compact packaging because powerful electric motors are designed to fit within the space of a conventional automatic transmission • 300-volt battery pack is larger than typical battery, but fits in without compromising passenger space. No plug-in is required | |
