(from Cadillac Press
Release) Cadillac ELR Electrifies the Luxury Market
Luxury coupe blends dramatic
design, industry-leading extended range technology
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.
Manufacturing
The Cadillac ELR will be
manufactured at General Motors’ Detroit-Hamtramck Assembly Plant,
the world’s only automotive manufacturing facility that
mass-produces extended-range electric vehicles for global markets in
21 countries. It is also home to Southeast Michigan’s largest
photovoltaic solar array. The 264,000-square-foot feature generates
up to 516 kilowatts of electricity – enough to charge 150 ELRs per
day.
Cadillac has been a leading luxury auto brand since 1902. In recent
years, Cadillac has engineered a historic renaissance led by artful
engineering and advanced technology. More information on Cadillac
