Test Drive Results Cadillac ELR Plugin Hybrid Electric Car

The innovative Cadillac Converj Concept, a dramatic luxury coupe with extended-range electric vehicle technology, is moving forward as a production car that will be called the Cadillac ELR.
Development of the ELR is just underway, so details on performance, price and timing will be announced later.
The Cadillac ELR will feature an electric propulsion system made up of a T-shaped lithium ion battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car without using gasoline or producing tailpipe emissions. When the battery’s energy is low, the ELR seamlessly switches to extended-range mode to enable driving for hundreds of additional miles.

The innovative Cadillac ELR Plugin Hybrid Electric Car is a new Concept. It’s a dramatic luxury coupe with extended-range electric vehicle technology. This was moving GM forward as a production car called the Cadillac ELR. THIS CAR ROCKED!

The Cadillac ELR featured an electric propulsion system made up of a T-shaped lithium ion batteries. That’s an electric drive unit and a four-cylinder engine-generator. Therefore, it uses electricity for about 53 miles. Yes folks as its primary source to drive the car! Aka without using gasoline or producing tailpipe emissions. So when the battery’s energy is low, the ELR switches to extended-range mode. Aka the gas hybrid mode. That’s easy enabling you to drive for another 238-250 plus miles.

“The concept generated instant enthusiasm,” said Don Butler, vice president-Cadillac Marketing. “Like other milestone Cadillac models of the past, the ELR will offer something not otherwise present – the combination of electric propulsion with striking design and the fun of luxury coupe driving.”

Cadillac selected the name ELR to indicate the car’s electric propulsion technology. That’s in keeping with the brand’s 3-letter international model naming convention.

The Converj Concept sparked the idea of combining the desirability of a grand touring coupe with electrification. That was said Ed Welburn, GM vice president, Global Design.

“There’s no mistaking it for anything but a Cadillac, an aggressive, forward-leaning profile and proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2,” Welburn said.

Cadillac also recently announced it will add two new vehicles to its product lineup in 2012, the XTS large luxury sedan and an all-new luxury compact sedan codenamed ATS.

Let’s talk about these special paddles on the steering wheel now!!


Luxury coupe’s Regen on Demand redefines the role of paddle shifters  
DETROIT – Paddle shifters take on new meaning in the Cadillac ELR, the brand’s first electric vehicle with extended range capability that goes on sale in early 2014.
Unlike traditional performance vehicles where the steering wheel-mounted paddles allow drivers to upshift and downshift the

mechanical transmission, Cadillac ELR’s paddle shifters enable the driver to temporarily regenerate energy and store it as electricity in the battery pack for later use.
ELR’s Regen on Demand feature is unique to the compact luxury coupe and builds on Cadillac’s performance-bred heritage.
“Regen on Demand enables ELR drivers to actively re-capture energy when slowing down, such as when  approaching slower traffic or setting up for a tight turn,” said Chris Thomason, ELR chief engineer. “This allows the driver to take more active role in the electric vehicle driving experience.”
To engage Regen on Demand, the driver simply takes his or her foot off the accelerator and pulls back on either the left or right steering-wheel paddle to begin regenerating electricity. When engaged, Regen on Demand provides vehicle deceleration that is more than what a typical vehicle experiences while coasting, providing control and dynamic performance characteristics similar to downshifting in a manual-transmission vehicle. The feature does not bring the vehicle to a full stop.

Releasing the paddle disengages Regen on Demand, allowing the vehicle to coast normally. The driver can engage and disengage Regen on Demand as desired and as traffic conditions allow.
“Pulling back on the paddle to slow down allows the ELR driver to keep their foot close to the throttle, ready to accelerate,” Thomason said. “It provides a more engaged, satisfying driving experience, and when you consider the added benefit of re-capturing energy, it’s also a smart thing to do.”
During regenerative braking, the system converts the vehicle’s momentum to electrical power and stores the energy in the T-shaped battery pack located underneath the center of the car.
ELR includes a blended regenerative braking system that will recapture a majority of the energy in a vehicle’s momentum rather than losing it as heat in the brakes, which is common with conventional vehicles. When the brakes are applied, energy is recaptured, as the vehicle slows. If more brake force is applied, ELR automatically blends in friction brakes to apply greater stopping power for more urgent stops.
The system has a standard 4-channel anti-lock braking system and includes electronic Brake Force Distribution, which uses independent rear control for improved stability and braking during cornering, as well as more effective use of the rear brakes as vehicle loading occurs.
Also, the disc brake system features vented front and solid rear Duralife rotors with Ferritic Nitro-Carburizing (FNC) finishing technology to reduce corrosion and deliver longer life.
