DUBAI – Advanced technologies in the 2015 GMC Yukon lineup’s new EcoTec3 V-8 engines deliver more power with greater efficiency – including segment-best city and highway fuel efficiency with the Yukon’s standard engine and the segment’s highest power and torque ratings for the Yukon Denali models.

Yukon and Yukon XL feature a standard 5.3L engine, rated at 355 horsepower and 519 Nm of torque, which enables EPA-estimated 14.7 L/100km in the city and 10.2 L/100km on the highway for 2WD models – efficiency increases of nearly 10 percent on the highway and 7 percent in city driving, compared to previous models.

Yukon Denali and Yukon XL Denali models feature an exclusive 6.2L V-8 rated at 420 horsepower and 624 Nm of torque delivering nearly 19 percent more horsepower and about 20 percent more torque. No other full-size SUV offers as much power and torque giving customers the confidence of power on demand for any situation and the benefit of greater efficiency.

Both of the new EcoTec3 engines feature state-of-the-art technologies, including direct injection, Active Fuel Management (cylinder deactivation), continuously variable valve timing and an advanced combustion system, designed to make the most of power, torque and efficiency across a broad range of operating conditions.

Improved engine mounts, electronic throttle control, adaptive exhaust systems, improved aerodynamics and other technologies help the engines operate in four-cylinder mode longer with Active Fuel Management, further increasing efficiency.

A Hydra-Matic 6L80 six-speed automatic transmission is paired with both engines and contributes to efficiency with reduced engine speed on the highway.

Additional features on the EcoTec3 engine family include:

  • Weight-saving aluminum engine block: A lightweight aluminum block with iron cylinder liners provides a light, rigid foundation for a smooth and strong engine. The design helps maximize strength and minimize vibration.
  • Efficiency-enhancing oiling system: The oiling system incorporates a new variable-displacement oil pump that enables more efficient oil delivery, based on the engine’s operating conditions. Its dual-pressure control enables operation at a very efficient oil pressure at lower rpm, and then delivers higher pressure at higher engine speeds to provide a more robust lubrication.
  • Oil-jet piston cooling: At higher engine speeds, small jets spray oil on the underside of each piston to help reduce piston temperature, enabling the engine to maintain maximum horsepower and torque. It also reduces engine noise.
  • PCV-integrated rocker covers: New domed rocker covers house a patent-pending integrated positive crankcase ventilation system that enhances oil life, reduces oil consumption and reduces exhaust emissions – three times the oil/air separation capability of previous engines.
  • “Saw-cut” exhaust manifolds: The cast-iron exhaust manifolds were developed to improve durability and sealing, and reduce operating noise. The exhaust manifolds also feature triple-layer stainless steel heat shields, which limit heat transfer to the engine bay and help further reduce noise.
  • Cooling system, humidity sensor and more: A contribute to greater efficiency and reduced maintenance requirements.

The 2015 Yukon is available in showrooms across the Middle East. Its starting MSRP price in the UAE is AED175,000 for the 2WD and AED186,000 for the 4WD.

Built on the philosophy of ‘Commands Respect’, GMC has built pickups since 1902. With a rich heritage in the Middle East and an impressive 111 years of presence, innovation and engineering excellence is built into all GMC vehicles. The brand is evolving to offer more fuel-efficient pickups, crossovers and SUVs.

The GMC portfolio in the Middle East features Terrain small SUV and Acadia crossover. The 2014 Sierra half-ton pickup boasts all-new powertrains and design and is the most capable and powerful trucks ever built by GMC. Every GMC model, including Yukon and Yukon XL full-size SUVs, is now available in Denali luxury trim. GMC also offers customers a high-level aftersales service experience.
