We knew this was coming. The entire lineup of General Motors SUVs is getting an overhaul, and the American company decided to start with a blowout, releasing the Chevy Tahoe, Chevy Suburban, and GMC Yukon (Denali and XL models) all at the same time at a launch in New York City. GM wants the world to know that full-sized SUVs are still very much relevant. And that's why they're waiting to save the Cadillac Escalade (the best) for last, unveiling the flagship on Oct. 7th. 

The main differences between the four SUVs all come from the front ends. The GMCs have much more elegent looks, with the bleeding spiked headlights, which are very similar to the design cues that Cadillac has been using (expect a more exaggerated version for the Escalade). The Chevys, however, have a much different approach, almost looking like a 2014 Range Rover headlight with an extra added fin. It's ... an interesting makeover for the two best-selling full-sizers in the U.S. They say the overall design is for aerodynamics. 

Under the hoods are 5.3L EcoTec3 V8 engines with 355hp, which GM is saying are going to be more efficient than previous years (nothing official yet in terms of EPA). This engine will run with a Hydra-Matic six-speed automatic transmission, which will have TapShift control, Tow/Haul mode, and Auto Grade Braking integrated into the system. The vehicles will also have electric steering, new for these SUVs, four-wheel-disc brake system, and a "stronger frame with a wider track." Like many new utility vehicles, these will all include 360 radar and camera protection, as well. Click thorugh to see all four from multiple angles.
