2013 NAIAS: Cadillac unveils the all-new 2014 ELR

Article by Christian Andrei, on January 15, 2013

The new 2014 Cadillac ELR made its official debut today at the 2013 North American International Auto Show and as expected, this is the first application of Extended Range Electric Vehicle technology by a full-line luxury automotive brand. 

Regarding the design, the Cadillac ELR is inspired by the Converj Concept and comes with an aggressive, forward-leaning profile and new vertical headlamp and taillamp elements, which are a brand tradition since 1948. Although the Chevrolet Volt has a drag coefficient of 0.28, the Cadillac ELR is not helped by its design and according to the official press release its drag coefficient is 0.30.

Inside, the ELR offers seats for four persons and the leather-trimmed interior blends authentic chrome and wood accents. The Cadillac CUE with Navigation is offered as standard and it can be accessed using the eight-inch, full-color capacitive touch screen found in the center of instrument panel. Regarding the driving experience, the Cadillac ELR is able to deliver 295 lb.-ft. of torque (400 Nm), which means about 12 percent more than the 3.6L V-6 in the SRX.

Powertrain

As expected, the Cadillac ELR is powered by the same 1.4-liter gasoline-powered electric generator found on the 2013 Chevrolet Volt and capable to deliver a total of 207 hp (154 kW).

The ELR also comes with a T-shaped 16.5 kWh lithium-ion battery pack, which is located along the centerline of the vehicle, between the front and rear wheels in order to provide optimal weight distribution. The 5.5-foot-long (1.6 m), 435-pound (198 kg) pack supplies energy to an advanced electric drive unit capable of 295 lb.-ft. of instant torque (400 Nm) to propel the vehicle.

Using just the energy from this battery pack, the ELR will be able to travel about 35 miles or 56 km using just electricity. A driver-selectable Hold mode directs when the ELR uses its electric generator. Just like the Chevrolet Volt, the ELR can be recharged from a 120V electrical outlet or a dedicated 240V charging station.

Using the 240V outlet, the ELR can be completely recharged in almost 4.5 hours, depending on the outside temperature. Once the vehicle is plugged in, owners can schedule either immediate or delayed charges, even coordinating charging according to departure time or when electricity rates are lower.

Using the RemoteLink app, the ELR owners will be able to manage and monitor the ELR online. The ELR’s battery is covered by an eight-year/100,000-mile warranty. Industry-leading Extended Range Electric Vehicle (EREV) technology provides full driving range exceeding 300 miles (480 km), combining pure electric driving and an efficient, range-extending generator.

Cadillac ELR

DETROIT – Cadillac unveils the 2014 ELR today at the North American International Auto Show. The sleek luxury coupe features the first application of Extended Range Electric Vehicle technology by a full-line luxury automotive brand.

"ELR is an unprecedented combination of luxury, advanced engineering and progressive design in a coupe that is both sporty and environmentally friendly," said Bob Ferguson, Cadillac global vice president. "This is a pivotal moment in Cadillac's history, as we continue our product-driven expansion."

The ELR delivers on the promise of the Converj Concept on which it is based. The exterior establishes a new, progressive proportion for the brand while the interior introduces a new design theme that will define future Cadillac models, emphasizing modern elegance, technology and precisely crafted details.

Industry-leading Extended Range Electric Vehicle (EREV) technology provides full driving range exceeding 300 miles (480 km), combining pure electric driving and an efficient, range-extending generator.

"ELR marks a fresh, even surprising new dimension of Cadillac," Ferguson said. "An additional aspect of ELR's appeal to will be exclusivity. It will be a specialized offering produced in limited numbers."

ELR's confident and responsive EREV driving technology is enhanced with exclusive Regen on Demand and selectable drive modes that enhance driving and make the most of efficiency. Regen on Demand allows the driver to temporarily regenerate energy from the ELR's momentum into electricity that can be stored in the battery pack for later use. It is engaged via steering-wheel paddles adapted from traditional performance cars.

The industry-leading, proven EREV technology is uniquely tuned for Cadillac in the ELR. Most daily commutes will require zero gasoline with zero emissions. Longer trips are free from electric-vehicle range anxiety because EREV technology enables the same long-distance freedom as a conventional car.

Additional vehicle highlights include:

Enhanced AT-PZEV emissions meet California's criteria for single-occupancy access to high occupancy vehicle lanes
Light-emitting diode (LED) headlamps, daytime running lamps and taillamps, as well as signature front and rear lighting elements
Twenty-inch wheels paired with tires designed to balance responsive handling and a comfortable ride with efficiency
Interior design featuring cut-and-sew accented leather incorporating sueded microfiber, chrome, wood and available carbon fiber finishes throughout
Cadillac CUE with Navigation is standard. CUE is Cadillac's breakthrough system for connectivity and control, using Natural Voice Recognition, capacitive touch and hand gestures used on smart phones and tablets
Programmable charging schedules and downloadable energy efficiency reports available online and through smartphone notification charging alerts
Cadillac's advanced active safety features, including Safety Alert Seat, Forward Collision Alert and Lane Departure Warning, along with available Side Blind Zone Alert with Rear Cross-Traffic Alert and full-speed-range adaptive cruise control
Advanced chassis and suspension systems, including HiPer Strut front suspension, compound-crank with Watts link rear suspension and Continuous Damping Control, which adjusts damping every two milliseconds for optimal ride and handling in all conditions
Standard premium Bose 10-channel audio system with active noise cancellation.
ELR production begins in the United States in late 2013 with sales starting in early 2014 in North America and expanding to global markets including China and Europe.

Design
The Cadillac ELR has an aggressive, forward-leaning profile that introduces a new, progressive theme and proportion in Cadillac's design evolution. It carries over almost unchanged from the 2009 Converj concept that inspired it. The overall shape is reinforced by a prominent, sweeping body line accented by 20-inch wheels pushed to the edges of the body.

"The ELR represents a new dimension of Art & Science, the guiding philosophy of Cadillac," said Mark Adams, Cadillac design director. "Cadillac's DNA is innovation, with dramatic and provocative design. ELR delivers this in a luxury coupe that stands alone among major luxury brands globally."

Vertical headlamp and taillamp elements create Cadillac's signature for the ELR, day or night and from the front or rear – a brand tradition since 1948.

Aerodynamics play a crucial role in the design as airflow is managed to help the vehicle slip through the air with minimal drag. A flush front fascia and grille – with active shutters behind the grille opening – as well as tapered fascia corners, enable air to move easily around the car to reduce drag. In the rear, sharp edges and a carefully designed spoiler also manage airflow. An aggressive rake on the windshield and back glass help reduce turbulence and drag and contribute to ELR's 0.305 coefficient of drag.

Inside, the ELR's classic 2+2 layout is driver focused, emphasizing modern luxury, connectivity and precisely crafted details. The leather-trimmed interior blends authentic chrome and wood accents – and available carbon fiber trim – as well as a sueded microfiber headliner and steering wheel covered in leather and sueded microfiber. Additional features include:
• Eight-inch configurable instrument and driver information displays, offering four configurations ranging from elegantly simple to technologically enhanced information
• Auto-glide/power-assisted covered storage/cup holder in the center console
• Fold-down rear seat backs accommodate longer items, including multiple sets of golf clubs
• LED-powered accent lighting in the instrument panel and doors
• Available Opus semi-aniline leather seating.

Cadillac CUE with Navigation is standard and accessible through a large, eight-inch, full-color capacitive-touch screen in the center of the instrument panel. It supports the electrified driving experience with displays on driving efficiency, energy usage, charging options and more, in addition to a broad range of infotainment options.

Using Cadillac CUE via the touch screen features gesture recognition, proximity sensing (revealing information when needed) and a three-core microprocessor for faster response. Some features are accessible via steering-wheel controls and the motorized screen pivots up to reveal a hidden storage compartment with a USB port for phones and other personal items.

Driving Experience
The Cadillac ELR's dramatic design is matched with an engaging driving experience, supported by the EREV propulsion system calibrated for uncompromising performance. With 295 lb.-ft. of torque (400 Nm) – about 12 percent more than the 3.6L V-6 in the SRX – acceleration in the city and on the highway, including merging and passing, is achieved with reassuring power on demand.

Driving confidence is further enhanced by advanced suspension and damping systems, including Continuous Damping Control – which adjusts damping every two milliseconds – to maintain optimal vehicle ride control over varying road surfaces and profiles. The ELR rolls on 20-inch wheels with specially engineered low-rolling-resistance tires designed to balance excellent control and cornering capability with efficiency.

A solid, stable foundation underpins the ELR, featuring a body-frame-integral structure with main underbody rails running continuously from front to rear. Advanced, high-strength steels add strength and conserve weight. Additional contributors to the ELR's driving experience include:

Wide front and rear tracks – 62.1 inches (1,578 mm) in front and 62.4 inches (1,585 mm) in the rear – along with a long wheelbase (106.1 inches / 2,695 mm) and a low center of gravity
HiPer Strut front suspension featuring lightweight forged aluminum components for reduced weight and more nimble, responsive action
Dual-pinion, rack-mounted electric power steering system with premium ZF steering gear designed to provide excellent feedback while helping to save fuel
A semi-independent rear compound-crank suspension with Watts link that incorporates weight-optimized trailing arms to absorb lateral forces, allowing the suspension to be tuned to handle vertical, forward and rearward motions
Hydraulic ride bushings in the front and rear suspensions
An electro-hydraulic regenerative brake system that captures energy and sends it to the battery pack
Standard chassis control systems include antilock brakes, traction control and StabiliTrak electronic stability control.
Because the ELR operates so quietly in all-electric mode, a driver-activated feature sounds a noise to alert pedestrians, particularly those with visual impairments, in an intersection. The alert was developed in conjunction with the American Federation of the Blind.

Propulsion and Charging Technology
The ELR is powered by GM EREV technology, combining pure electric drive and an efficient, range-extending 1.4L gasoline-powered electric generator capable of 154 kW (207 hp) of total system power.

The ELR's battery is a T-shaped, 16.5 kWh lithium-ion battery pack, located along the centerline of the vehicle, between the front and rear wheels for optimal weight distribution. The 5.5-foot-long (1.6 m), 435-pound (198 kg) pack supplies energy to an advanced electric drive unit capable of 295 lb.-ft. of instant torque (400 Nm) to propel the vehicle. Using only the energy stored in the battery, the ELR will deliver a GM-estimated range of about 35 miles (56 km) of pure electric driving, depending on terrain, driving techniques and temperature.

A driver-selectable Hold mode directs when the ELR uses its electric generator. This feature helps optimize the electric-driving experience, allowing owners who mix city and highway driving to save the battery charge for city travel, where the ELR EV mode operates most efficiently.

Charging the ELR's battery can be done with a 120V electrical outlet or a dedicated 240V charging station. The vehicle can be completely recharged in about 4.5 hours using a 240V outlet, depending on the outside temperature.
Once the vehicle is plugged in, owners can schedule either immediate or delayed charges, even coordinating charging according to departure time or when electricity rates are lower. Owners also can manage and monitor the ELR online or with their smartphone and RemoteLink, a mobile app powered by OnStar.

The ELR's battery is covered by an eight-year/100,000-mile warranty.
