GM's big SUVs reward fans for their patience Vehicles offer quieter interior, improved powertrain

摘要

It has been eight years since the last redesign of the Chevrolet Tahoe and Suburban and GMC Yukon and Yukon XL. Some owners have been waiting even longer than that. The average General Motors big SUV has been lumbering along the roads for about 11 years. That means there ought to be plenty of pent-up demand for the 2015 models, in spite of sticker prices that range from an extra $2,500 for a popular Tahoe model to nearly $7,000 more for a Yukon Denali XL. The SUVs feature clean, contemporary designs, a more powerful yet more fuel efficient powertrain and a hushed interior that has been improved to vanquish some key complaints about the outgoing generation. They began arriving in dealerships last month.
