Cadillac ELR: More Details On How the Volt Will Become a Caddy (Hint: More Power)
Bit More of Everything to Maintain Performance
What we’re hearing is that the production ELR will swap the Volt’s 1.4-liter four for a naturally aspirated variant of the new Opel-developed Ecotec MGE. This all-new powerplant is the architectural base for a future family of low-emissions, direct-injection four-cylinders that will eventually replace most of GM’s Family 1 engines. Although the exact displacement of the ELR’s version is not known at this time, the block has been engineered to expand to as much as 2.0 liters. We’d expect to see the final version in the Caddy displace 1.8 liters at most, however. In order to keep the ELR’s pure electric range at least at the level of the Volt, battery capacity will be increased to more than 17.0 kWh; this will be accomplished by increasing the pack’s length and adding cells. Expect the “T” configuration of the pack to carry over. The Volt’s 4ET50 continuously variable transmission/drive unit will be revised to match its power output and electrical generation capacity to the new engine.
