CANEPA — GM — SO-CAL
HHR 2008 Land Speed Record Program
We're going to Bonneville in 2008!
Canepa Design and So-Cal Speedshop in association with GM are taking the HHR back to Bonneville in August of 2008 in attempt to brake the G/Blown Fuel Competition Coupe class record. The G/Blown Fuel Competition Coupe record stands at 226.835 mph, a lofty mark established 15 years ago.
We are actively seeing partners on this program if you
are interested please email us.

The Car
Chevrolet HHR
Purpose-built for land speed racing at the Bonneville Salt Flats, and running
in the G/Blown Fuel Competition Coupe class, the HHR has been chopped seven
inches, stretched in the hood four inches and converted from transverse front-wheel
drive to longitudinal rear-wheel drive. The turbocharged and intercooled 2.0L
Ecotec engine, producing in excess of 1000 horsepower, was designed and assembled
by GM Performance. The powerplant drives an air-shifted five-speed transmission
and a quick-change rear end. On its second-ever shakedown run the HHR went
208.690 MPH
Making its debut in 2005, the Chevy So-Cal Bonneville HHR topped 208 mph on the Salt Flats, and attracted huge crowds in the pits and at the start line. Even though it didn’t get a chance to top the 16-year-old 226.835 mph record in G/BFCC class (G Class/Blown Fuel Competition Coupe), the HHR achieved its objective of creating a buzz around Chevy’s latest crossover vehicle. GM engineer and Bonneville record holder Jim Minneker drove the HHR in the G/BFCC class in 2005 and 2006.
In 2006 the HHR crashed at over 250 MPH when Minneker lost traction when the parachute deployed. Minneker was beating the previous record of 226.835 in the G/BFCC class (G Class/Blown Fuel Competition Coupe) with a qualifying run of 246.686 mph when the HHR lost traction at the five-mile mark of the long course. The vehicle’s terminal speed at the time was 249.793 MPH. Minneker was able to walk away from the incident with nothing more than a stiff neck.
“We take any kind of racing very seriously, and the safety of our race drivers is always of paramount importance,” said GM Performance Division Executive Director Bob Kruse. “GM’s technology, equipment and procedures for racing are world class and today’s incident is a prime example. The structure of the HHR was outstanding, and it performed exactly as it was intended for this ultra high speed type of incident.”
Why an HHR for the salt? Al Oppenheiser, director of Concept Vehicle Engineering, explained: “The message from GM’s leadership was clear - ‘Every employee needs to do what they can to communicate the energy and excitement of the great new products we’re launching, such as the HHR.’ At the GM Performance Division, we felt that there was no better way to contribute to the excitement of the HHR launch than to build an HHR racecar that could shatter the world speed record in the very competitive G/Blown Fuel Competition Coupe class.
“The grassroots nature of Bonneville reaches audiences far and wide, and the GM Performance Division continues to build momentum each year with our presence,” Oppenheiser added. “A new speed record for the HHR would be a great contribution from our team to support the GM leadership’s message.”
The New Car
Learning from the experiences of 2006, a completely new car has been designed
and constructed.
The Ecotec engine in a production HHR is mounted transversely and drives the front wheels; in the Bonneville version, the engine is mounted longitudinally and powers the rear wheels. Occupying the space once reserved for the front seats, the Bonneville HHR’s mid-mounted Ecotec delivers its prodigious torque via an air-shifted five-speed racing transmission and a quick-change rear end.
The HHR’s Ecotec is essentially identical to the engine we use in the Cobalt SS racecar at Bonneville. It’s turbocharged and intercooled, it burns methanol fuel, and it produces 1,000+ horsepower at full boost. With the HHR’s 5-speed gearbox and quick-change rear end we have the ability to optimize the gear ratios. The racing transmission allows us to change individual ratios to optimize the rpm drop during gear changes based on the engine’s power curve. We can also optimize top speed for the conditions at Bonneville by changing the rear end’s final drive ratio.
While the HHR’s styling has retro elements, its aerodynamic attributes are state-of-the-art. The team worked closely with the production HHR aerodynamicist and in-house aerodynamic experts at GM. All of the Bonneville HHR’s aero development was done at the GM Aerodynamic Laboratory in Warren, Mich.
So-Cal Speed Shop brought its own flair to this project. “It’s always a challenge chopping a modern vehicle,” said So-Cal Speed Shop President Pete Chapouris. “The HHR’s body panels are galvanized steel, and we had to chop four doors and fabricate a new tailgate to house twin parachutes. The roof incorporates NASCAR-style flaps and side rails to prevent the car from becoming airborne and to help slow it down should it spin. We installed a Funny Car-style escape hatch in the roof as an additional safety feature.”
So-Cal Speed Shop fabricators Robin “Silky” Silk and Paul Rivera constructed the Bonneville HHR’s tubular chassis. Inspired by the Pro Mod chassis used in drag racing, the HHR framework is a double-rail design. The engine can be easily removed for service by sliding it forward on the upper chassis rails. The front suspension incorporates lightweight MacPherson struts and the rear suspension is a four-link system with coil-over shock absorbers.

So-Cal Speed Shop
Founded in 1946 by Alex Xydias the So-Cal Speed shop has been at the cutting
edge of the Hot Rod movement and Land Speed record racing ever since. In the
1950 the famous So-Cal designed and built “bellytankers” were
running at over 200MPH at Bonneville. They had also built the first hot rods
to go 160, 170, 180 and 190 mph. Alex Xydias and So-Cal Speed shop president
Pete Chapouris were selected as two of the Top 100 Most Influential People
in the high-performance industry and, as such, were inducted into the Hot
Rod magazine Hall of Fame in 1997.
So-Cal in partnership with GM Performance built three new cars for a 2006 land speed record attempt – the radically redesigned 2006 Chevy So-Cal HHR, the Chevy So-Cal Cobalt SS race car and the Ecotec Lakester, which set a 189.205 mph speed record in the G/BGL class and is a modern-day replica of the famous So-Cal belly tank Lakester.
So-Cal is responsible for the design and construction of the
HHR land speed record car.

The Event
Bonneville Land Speed Record
Our goal it to break the 16-year-old 226.835 mph record in G/BFCC class
(G Class/Blown Fuel Competition Coupe) at the Bonneville Speed Week
The Bonneville Salt Flats
There was a time, centuries ago, when the Great Salt Lake covered an area
of 5,000 square miles. Today, what remains of that massive lake is a very
unique and special place that is also the home of one of the world’s
most unique racetracks. There are lots of racetracks in the world. But this
is the one where they go the fastest.
The salt flats were first used for motor sports in 1912, but didn’t become truly popular until the 1930s when the Ab Jenkins and Sir Malcolm Campbell competed against each other to set the world land speed record.
For many of people, racing at Bonneville represents the last area of motorsports where people are encouraged to come up with their own ideas and try them out. The technical challenge of designing and building a vehicle to go faster than anyone has gone before is extremely difficult. Bonneville is the ultimate test bead for state of the art engineering and automotive technology.
To an outsider, it would appear that straightaway speed trials driving couldn’t be easier. No curves or turns to worry about, no flag waving starter to watch before you start down the drag strip, and no competitor beside you to watch. Just “stab it and steer it.”
Yet it’s quite the opposite. The salt surface tends to be slippery at best. With any significant amount of horsepower, even the best handling vehicle can be a handful. There is the vibration and the fighting to keep the rear end, connected to the salt by only two tiny patches of treadless rubber, from swapping places with the front end. It’s a thrill that few people will ever experience.SCTA — Southern California Timing Association, Inc.
Formed in 1938, the SCTA is the sanctioning body for land speed record runs at the Bonneville Salt Flats. Each year in August, the Southern California Timing Association and Bonneville Nationals Inc. organize a Speed Week, which attracts several hundred drivers who compete to set speed records in a range of categories.
