Compared with the modern and sophisticated European luxury SUVs with which it’s cracked up to compete, it’s oversized and poorly packaged.
It drives very much like ‘truck’ 4x4s made elsewhere in the world used to, before monocoque construction and advanced chassis technology made them so much better behaved. And yet, even with an American truck this old-school, petrol-electric propulsion is now part of the mix.
The notion of hybridising a V8-engined behemoth like this in the name of eco-worthiness seems a rather incongruous one to put it politely.
Still, Porsche has done very much the same thing with the equally ostentatious automotive statement that is the Cayenne, and Lexus has quietly been getting on with selling useful numbers of its appealing RX SUV hybrid for some time now.
Both of those manufacturers, however, chose to mate their fuel-saving electric tech to an efficient V6 engine (we’re talking relatively here). Not so Cadillac. Instead, it has kept a mighty V8 under the Escalade’s bonnet, albeit one reduced in capacity from the non-hybrid version’s 6162cc to a marginally more parsimonious 5967cc.
In non-hybrid form the Escalade’s mighty V8 puts out a hefty 409bhp and 415lb ft of torque. It also returns just 19.5mpg on the combined cycle while contributing 339g/km of CO2 to the atmosphere. In contrast, the price for a cleaner, greener conscience is that the petrol-electric hybrid produces just 337bhp and 365lb ft, but claimed combined economy improves to 25.9mpg with CO2 emissions falling to 256g/km. Hardly Prius-rivalling figures. But like we’ve already said, these things are all relative.
The petrol-electric Escalade uses GM’s two-mode hybrid system, which mostly operates as a CVT but also has four fixed gears that are used when the Caddy’s a-haulin’. And given the vehicle’s 2.7 tonnes, it’s easy to see the sense of harnessing its kinetic energy when coasting and braking.
The electricity generated is stored in a 300-volt battery stored under the middle row of seats – the Escalade swallows it almost unnoticed – which propels it at low speeds. The Atkinson-cycle 332bhp 6.0-litre V8 has automatic stop-start, and can also operate on four cylinders to save fuel.
