Bentley has pulled the wraps off its heavily-updated Continental GT, and the changes are enough for the British marque to consider this an entirely new generation. While it rides on the same chassis as before and features the same general proportions, the big change here is the loss of the W12 engine, which has been offered on the grand tourer since its introduction more than 20 years ago. Taking its place is an entirely new plug-in hybrid V8 powertrain, which brings increases in both power and weight. For now, Bentley is only showing off the high-end Speed variant, but it shouldn't be too long before we see the rest of the overhauled lineup.
