The Cadillac-fosued outlet asked the engine’s chief engineer, Jordan Lee, whether motorsport engineering firms such as Pratt & Miller or teams like Wayne Taylor Racing are considering using the all-new DOHC V8 LTA engine for racing applications. His reply: “If they’re using it, I’m not aware of it.”
Cadillac has typically used torquey push-rod-style engines such as the LSA and LT4, otherwise knows as Overhead Valve (OHV), for its high-performance V-Series vehicles, while at the same time using variants of those engines in its motorsports efforts, namely the now-retired CTS-V.R that dominated the Pirelli World Challenge as well as the Cadillac DPi-Class racers that currently compete in IMSA. In that regard, the new 4.2L DOHC LTA engine, which is supposedly exclusive to Cadillac, might represent a change to that formula for future V-Series Cadillac offerings, but it apparently won’t be used for motorsport applications. Currently, the LTA is used in the 2019 Cadillac CT6 and CT6 V-Sport.
Cadillac Society also mentions that Lee might be pulling a fast one, since he also told the publication that even if he did know whether or not race teams were testing an LTA-based race engine, he wouldn’t tell.
