A Cadillac model based on the Chevrolet Volt – dubbed the Cadillac ELR -- is an idea that has captured the interest of consumers who are looking for performance as well as fuel efficiency. We know that the Cadillac ELR will make its production debut in 2013 as a 2014 model. The initial reports indicated that the ELR will use the Voltec extended-range setup that came directly from the Volt. However, it’s now believed that GM will trade the 1.4-liter, naturally aspirated engine and will instead use an Ecotec MGE powerplant developed by Opel. Cadillac is doing this because the ELR will increase its weight for its luxurious features.
It will be available with an all-new powerplant – the Ecotec MGE --- which will serve as the foundation for a future engine lineup for GM models. Majority of its existing Family 1 engines would be replaced. The MGE block is built to increase by up to 2.0-liters in displacement. However, it’s likely that the production version of the ELR will be offered with a 1.8-liter. It’s not totally sure that GM will not use a turbocharger.
Cadillac will have to guarantee that the Volt-based ELR has a satisfactory fuel economy and electric range even when the model is heavier. The 2013 Volt has upgraded its battery pack to 16.5 kWh from 16 kWh, raising its electric range to 38 miles. This means that the ELR could make use of added storage capacity. However, this may mean that charging it will take longer and it will be heavier due to the higher-capacity batteries. It’s notable that the ELR will be priced higher simply because it is a Cadillac. The question now is if consumers are willing to pay this amount. [source: AutoGuide]
