Designers conjured fresh ideas, tricks to meet challenges

INCHEON, South Korea — General Motors’ South Korean design studio is setting
a new course for the company’s small cars with this fall’s arrival of the
Chevrolet Bolt EV.

The center was tasked in 2012 with designing the Bolt, the automaker’s most
iconic technological showcase since the Volt hybrid, because of its
expertise in bundling big content into small packages. The Bolt proved to be
one of its biggest challenges yet.

The project forced designers to try new tricks that may debut in other cars,
all while on a supertight timeline toward the production version’s unveiling
last January.

“It reminds you of what GM can do when we’re given a deadline and set to
it,” the car’s lead designer, Stuart Norris, said in a July 7 interview
here. Norris arrived at the Korea studio as director of advanced and
architecture design in 2012 and was promoted to managing director of design
on July 1, 2015.

“We broke the mold on the Bolt EV,” the British designer said.

GM executives wanted an EV that could generate serious volume. The design
should be expressive and distinct without veering into “science project”
territory, Norris said.

“We need to sell more of these electric vehicles, so we need something that
has more broad mass appeal,” Norris said. “The Bolt was a very significant
program for us.”

Typically, GM vehicle design is handled by two teams, one responsible for
the exterior, the other for the interior. But the Bolt was such a
high-stakes project, the company created a special team in Korea that would
integrate all aspects of styling.


With some 190 workers, the Korea design center is now GM’s third-biggest
styling studio, after centers in the U.S. and Europe. It is also the Detroit
carmaker’s hub for global small-car design, springboarding off the
experience in compacts that came through GM’s tie-up with Daewoo before
fully subsuming the South Korean automaker.

GM Korea has led the design of such cars as the Chevrolet Sonic, Spark and
Cruze as well as the Trax and Captiva crossovers. It also designs small cars
for emerging markets such as India.

The studio sits on the grounds of the company’s Bupyeong assembly plant and
engineering center in Incheon, just outside Seoul. GM doubled the size of
the design center in 2014, after spending $40 million on sweeping upgrades.

Norris said the studio now has 10 vehicle projects underway.


'Disaster for aero'
Mini and B-segment vehicles are its mainstays. But the Bolt broke new
ground. “It’s a bit of a segment buster,” Norris said. “We call it a
C-segment interior on a B-segment platform.”

The challenges began with trying to maximize drivetrain efficiencies for a
compact electric vehicle with hatchback proportions, he said.

Another trial was eking out every last inch of interior space.

There were no silver-bullet solutions, just a relentless series of tweaks
and adjustments.

“There’s big-picture stuff, and then there’s just detail, detail, detail,”
Norris said.

The Bolt has a drag coefficient of 0.32, Norris said. That compares with a
superslippery 0.24 in the Toyota Prius hybrid. But the challenges were
steeper given the Bolt’s squat, wedge shape.

“It’s a disaster for aero,” said Norris, who worked for seven years on the
svelte silhouettes of sports car maker Jaguar before joining GM in 2004.

To improve air flow, Norris’ design team incorporated a spoiler and sharply
creased winglike canards along the tail edge of the car. Other tricks were
underbody paneling, air dams and active grille shutters that close at
certain speeds to streamline airflow. Designers even adjusted the radius of
the A-pillar, modified the mirrors and fine-tuned tire coverage.

No fewer than six full-sized iterations of the Bolt underwent wind-tunnel
testing.

Carving out room on the inside was another challenge.

“When we designed the Bolt EV, we kind of had this image of the vehicle as
the next-generation of family vehicle, a reinventing of what a family car
would be,” Norris said. “So it’s got this big spacious interior volume, a
ton of trunk space.”

'Unique execution'
Designers achieved an airy feel by bringing the windshield forward, lowering
the beltline to emphasize a glassy open canopy, flattening the floor and
pushing wheels to the corners.

A cantilevered center console hangs suspended from the dash, rather than
connected to the floor, enhancing the spacious atmosphere up front.

More compact packaging of the electric motor allowed the heating and air
conditioning unit to be pushed forward, creating even more cabin space. GM
also developed thinner seating that delivered 25 millimeters (1 inch) of
extra legroom.

Another fresh idea: front seats that are asymmetrical. The distance from the
center line of the seat to the armrest is shorter than the distance from the
center to the door.

The seat’s wide outer bolstering was needed to accommodate an airbag but
doesn’t provide much in the way of actual body support. Thus, designers
could do without the bolstering on the other side of the seat. The seats
look off-balance but allow for a wider armrest.

“How do we make this seat as narrow as we possibly can without making the
occupant uncomfortable? Well, we make the design asymmetrical,” Norris said.

Another big challenge was the liftgate. The taillamps are incorporated into
the lift door, rather than into the side body panels. That helped deliver
extra space in the trunk, but it complicated the work of delivering seamless
fit and finish, Norris said.

Finally, to squeeze every mile from the car’s battery-powered drivetrain,
lightweighting was a priority. Thus, the Bolt got an aluminum hood, liftgate
and doors to shed pounds.

“Small-car design has always been a challenging area because you’re trying
to deliver more for less,” Norris said. “This is a pretty unique execution.”

2017 CHEVROLET BOLT
]

General Motors was really excited about introducing the all-electric Chevy
Bolt earlier this year, being the only major automaker to bring a practical
200 mile range EV rival to Tesla’s Model 3 to market an entire year sooner.
The problem with the Bolt is that it wont be exciting to any American
buyers.

2017 Chevrolet Bolt: Meet America's $30,000 200-Mile Electric Car

In a recent profile of General Motors’ Korean design studio by Automotive
News, the new Chevy Bolt, which goes on sale later this year, was heralded
as a new standard for the automaker’s small vehicle design. The Bolt’s lead
designer Stuart Norris provided a detailed interview about the design
process, revealing an ultimately flawed approach to introducing an electric
car to the American consumers.

We can’t discuss the Chevy Bolt without bringing up Tesla’s success and its
approach to the “affordable” EV with the upcoming Model 3. The Chevy Bolt
will go on sale for right around $30,000 after incentives, offering an
electric range of 200 miles. The Tesla Model 3 is promised to start at a
similar price and offer a similar range. But that’s where the similarities
end.

As Tesla learned early on after introducing the Model S, which underwent a
minor face-lift to improve aerodynamics shortly after going on sale,
limiting drag on a design is the easiest route to improved fuel economy, or
in an electric car’s case, increasing range—which happens to be the biggest
concern over purchasing an electric car. That’s why aerodynamic efficiency
was the key focus behind the upcoming Model 3's design.

In the interview with Automotive News, Stuart Norris admitted that the goal
for the Chevy Bolt wasn’t aerodynamics, which, again, is the key factor in
extending the range of an electric vehicle, but instead the team obsessed
over maximizing interior space. From AutoNews:

The Bolt broke new ground. “It’s a bit of a segment buster,” Norris said.
“We call it a C-segment interior on a B-segment platform.” 

“When we designed the Bolt EV, we kind of had this image of the vehicle as
the next-generation of family vehicle, a reinventing of what a family car
would be,” Norris said. “So it’s got this big spacious interior volume, a
ton of trunk space.”
And it looks like a Honda Fit, but priced $10,000 higher.

Interior space on a compact car is an important factor in the design
process, for sure. GM’s goal to make what is ultimately just another
B-segment car severely compromised the Bolt’s aerodynamics, which Norris
blatantly states in the interview:

The Bolt has a drag coefficient of 0.32, Norris said. That compares with a
superslippery 0.24 in the Toyota Prius hybrid. But the challenges were
steeper given the Bolt’s squat, wedge shape.

“It’s a disaster for aero,” said Norris, who worked for seven years on the
svelte silhouettes of sports car maker Jaguar before joining GM in 2004.

To improve air flow, Norris’ design team incorporated a spoiler and sharply
creased winglike canards along the tail edge of the car. Other tricks were
underbody paneling, air dams and active grille shutters that close at
certain speeds to streamline airflow. Designers even adjusted the radius of
the A-pillar, modified the mirrors and fine-tuned tire coverage.

I understand the approach at attempting to normalize the electric car, but
this is where the team should have realized that the Chevy Bolt’s electric
drivetrain is a compromise to the practicality of the B-segment car they
were making.

Why not make a B-segment car with all of the “mold-breaking” innovations to
increase interior space, and pair that practicality with a small internal
combustion engine offering a much greater range and impressive fuel
efficiency over an electric car? Not to mention it would likely bring the
price of the car down without relying on incentives.

To the same note, why is GM trying to form an electric car, which relies on
aerodynamics and light weight for efficiency and practicality, into a
segment that is perfectly served by a more traditional design approach?

The main issue with the Bolt’s design is that it’s trying to be two things
at once, and fails at being a practical B-segment hatchback just as much as
it fails at being a practical electric car.

Why should I buy a Chevy Bolt, which has a limited range, impractical
refueling time compared to the competition, and a starting price almost
$10,000 more than something like a Honda Fit, which honestly looks almost
identical in design?

Tesla’s success at grabbing the attention and interest of American (and
global) buyers is that it makes electric cars attractive in both design,
practicality and performance.

The Chevy Bolt doesn’t look bad, but in the segment GM forced it into, it
doesn’t offer any more performance, practicality or style over the
competition while being sold for a much greater price.

Americans have already placed 370,000 orders for the Model 3, proving that
the market and interest for an affordable electric car exists. So why is the
Chevy Bolt trying so hard to pretend it isn’t an electric car?
