What platform will be next to receive the EcoTec3 and LT1 line of engines?
GM tipped its hat last week in revealing that nine models will have a Gen V-based motor by 2015. Today they followed that up by announcing the 2015 Chevrolet Tahoe and Suburban, as well as the GMC Yukon counterpart, would be the next vehicles to receive the potent and efficient 5.3L L83 and 6.2L L86 (Yukon only) mated to the 6L80E transmission. This begs the question, what vehicles will be next. If you count these three as well as the 2014 Corvette, Silverado and Sierra, that leaves three models remaining.
Here are the potential targets:
Cadillac Escalade- usually this model goes hand in hand with the Tahoe/Yukon, so it seems the most likely to be next on the list.
Avalanche- assuming GM is going to keep producing these pickup/SUV crossovers, then most likely they will also utilize a Gen V on the next redesign, which seems imminent given its relation to the rest of the truck line.
Corvette ZR1/Z07- there is no doubt that this is in the works, probably for a 2015 release. If this is counted as a separate model, look for a boosted version of the LT1 to make 650hp.
Cadillac CTS-V- they just redesigned the CTS, so it seems unlikely they will drop a Gen IV motor in the brand-new chassis, and its immense popularity makes it unlikely to be omitted from the lineup. The only stumbling block here is that most assuredly something more potent than the 460-horse LT1 is a necessity (given last year's model and the performance of the Vsport), requiring more R&D.
Cadillac full-size sedan: this brand-new rear-wheel drive model is definitely in the works, the only question is when. And it seems apparent that the up-level version (at the very least) will have a V-8, maybe even a boosted version with a V badge.
Camaro SS- with the design refresh for 2014, it seems the sixth-gen won't come out until the 2016 model year at least, which would be a more ideal time to drop in the LT1.
Chevrolet SS- this sedan was just launched, so it may take a few years before they can make the change over to the Gen V.
Buick GNX- stranger things have happened.
