GM V-8 Small Block LT5 Engine
The LT5 is believed to be an upcoming eight-cylinder engine from General Motors. As of this writing, GM has not shared any official information about the LT5.
Here’s what we expect to see from General Motors’ upcoming LT5 engine:
- Engine family: the LT5 engine family could be one of the following two things:
- If the LT5 motor is part of the fifth-gen Small Block engine family, then it will likely feature technologies that define that family, including Direct Injection and Variable Valve Timing.
- The motor could also feature Direct Injection and Variable Valve Timing if it is part of a different engine family, such as a DOHC configuration.
- Displacement: it is currently unknown how much the LT5 motor will displace, but we believe it to be over 6 liters.
- Naturally-aspirated or force-inducted: it is believed that the LT5 will use a form of force induction, most likely high-pressure twin turbo-charging.
Corroborating GM’s plans for an engine called the LT5 are two trademark filings by the automaker.
General Motors first filed for the LT5 trademark with the United States Patent and Trademark Office on April 2013 in the goods and services category as “engines for automobiles, sport utility vehicles, trucks and vans”. GM subsequently filed a second filing citing the same goods and services category in September 2016.
Rumors are pegging the LT5 as making over 700 horsepower.
We will have more specifications as they become available.
Currently, rumors peg the LT5 as being reserved for the upcoming C7 Corvette ZR1. It’s also possible that the motor could be used in a high-performance Cadillac model.
We will post LT5 pictures when the motor is officially announced by GM.
