2009 Cadillac Escalade Hybrid

• Competes with: Lexus RX 400h
• Looks like: A regular Escalade with the word HYBRID plastered all over it
• Drivetrain: 2-Mode Hybrid system with 332 hp 6.0-liter V-8 engine and electric motor
• Hits dealerships: Summer 2008

There is one thing that holds a lot of people back from buying a big, bold SUV like the Cadillac Escalade: They don’t want to be a pariah for hurting the environment. The new 2009 Cadillac Escalade Hybrid is the third full-size hybrid SUV from GM, following the Chevy Tahoe and GMC Yukon which go on sale later this year.

The Escalade has a bigger engine, though, which not only has the assistance of a hybrid powertrain, but also features active fuel management so that when the SUV is cruising at highway speeds four of the eight cylinders shut off. Along with the regenerative braking system and other fuel-saving technologies, GM says the mileage for the hybrid Escalade will improve by 50% over its gas counterpart. That means the Escalade should get 18 mpg, up from 12, using the new EPA estimates. The government hasn't given official numbers yet, but we'd expect the Escalade to follow the other 2-mode SUVs which have highway mileage identical to the gasoline-only versions. That would mean the Escalade's would likely stay close to the 18 and 19 mpg for AWD and 2WD models respectively.

The Escalade will start from a dead stop, and drive at low speeds, entirely on electric power. It will also roll on 22-inch wheels.

We’ll have more photos of the Escalade Hybrid later today. Until then, tell us if you think this is a good idea for Cadillac.

2008 Cadillac Escalade Sport Concept

• Looks like: The Escalade your local NFL running back drives
• Defining characteristics: Mesh grille and 24s
• Ridiculous features: This is understated for SEMA
• Chance of being mass-produced: Probably not much chance of this being a production model, but perhaps some of the accessories will be available

The Escalade was the first Cadillac to feature the bold new grille that has made its way across the lineup. That grille is wild, and its standard. The custom mesh grilles we’re seeing at SEMA look almost subdued in comparison. Actually, we’re pleasantly surprised that this concept isn’t as garish as it could have been.

Besides ridiculously large wheels — 24 inches — the Sport concept is lowered just two inches, has more horsepower — 550 — features a high-performance exhaust system and has retractable side steps. To say we’re surprised by this show of restraint is an understatement. A shot of the SUVs backside is below. Feel free to give us your feedback.
