Made in honour of Volvo’s 80th birthday, the Jacob is a retro-penned hotrod inspired by the first series-produced Volvo car, the ÖV4 (the Swedish abbreviation for Open Car, 4 cylinders) that gained the nickname “Jacob”. The hand-built aluminium body hotrod is based on a carbon-fibre chassis and it’s equipped with Volvo’s Flexifuel, five-cylinder turbocharged petrol engine that generates 265 Hp. The Jacob hotrod will be unveiled at the

On April 14, 1927, the very first series-produced Volvo car leaves the factory that was built alongside the workshop. The model is called the ÖV4 (the Swedish abbreviation for Open Car, 4 cylinders), but it soon gains a new pet-name - Jakob.
2005-2006: In Leif Tufvesson's workshop in the rural south of
On December 18, 2007, in a perfect grand finale to Volvo's 80th jubilee celebrations, the car is first revealed to Volvo Personbilar Sverige's highly impressed top management.
"Volvo has always been a special make for me. These were the cars I learned my skills on in my youth, and I also worked for a while at Volvo's concept-car department. So instead of obtaining inspiration from an old Ford, as is usually the case in Hot Rod circles, I wanted to build something that meant more to me personally. That's why I chose to bring together the most classic attributes of Volvo, the Jakob, and my own modern Hot Rod style," explains Leif Tufvesson.
Parked side by side, the similarities between old and new are remarkable. The curvature of the bonnet has exactly the same radius. The characteristic windscreen attachment pillar that runs down the body side follows the original in detail as regards dimensions, materials and the number of screws used. Equally identical is the radiator grille with its characteristic mesh pattern and diagonal bar that incorporates the classic iron symbol. The body has been built by hand from raw aluminium panels that were bent into their final shape using a hammer and English wheel. Exactly as it was done in the prototype workshop back in the 1920s.
That said, however, the differences are naturally also obvious. Hot Rod Jakob is far smaller than the original. It is a two-seater instead of offering space for four. And it has those typical Hot Rod attributes: large wheels, no wings and a muscular rear axle. And if you get a bit closer it is possible to see differences in terms of materials and details. The chassis is built of lightweight carbon fibre, just like today's most advanced racing cars, not from heavy steel beams as in bygone times. The brake discs are remarkably slim, but their huge diameter (450 mm front, 515 mm rear) guarantee that the braking surface is still going to be more than sufficient. The wheel spokes are made of aluminium instead of wood, but they are exactly the same in number. The massive tyres with their specially milled tread in the form of Volvo's iron symbol give an assertive, modern aura, while the charming luggage compartment at the very front - in actual fact an elegant leather case - instead conjures up images of white suits, straw hats and wide skirts.
The entire build is typical of Leif Tufvesson's style. Lean. Aesthetically elegant. Stylishly minimalist. Largely because most of the components have been hidden away inside the body. For instance the springs and dampers, the electrical components and exhaust system. The result is that the body and axles look like they are floating in the air.
A closer look at the seating compartment reveals deeply rounded backrests instead of a single flat bench, creating a robust and sporty atmosphere. The seats are upholstered in light brown hide. The piping, the upright rifling on the backrest, resembles the original, while the perforated flat upper section behind the seat echoes more modern styling cues. A glance at the instrument panels reveals no conventional gauges. Instead, all the functions are gathered into a single, in-house-developed instrument to the right of the steering wheel. The dial face changes colour and function when pressed. Press once: the ignition comes on and the button glows red. Press the clutch and the button turns purple. Press once more and the engine fires up smoothly at the same time as the button's colour turns Volvo Blue.
"I really love combining old solutions with my very own ideas. Creating a fine balance between high-tech and tradition that works seamlessly. Dusting off old parts to renovate a car to original condition is not something that appeals to me," says Leif Tufvesson.
But there are autoofcars2011.blogspottheless a number of classic Volvo parts in the Hot Rod Jakob. The steering wheel comes from a 1962 P1800, as do the gear lever gaiter and steering column. The brake pedal and brake master cylinder are from the 140 Series. Supplied by Volvo Genuine Classic Parts (Volvo has one of the industry's widest ranges of genuine manufacturer's spare parts). The M90 gearbox is Volvo's last rear-wheel drive variant and comes from a Volvo 960. The engine, on the other hand, is brand new - a powerful Volvo T5 converted to run on eco-friendly ethanol, all so as to underline the lifecycle approach to this entire project.
The Hot Rod Jakob project has challenged not only Leif's skills as a car builder but also perceptions of the Volvo brand. Just how does this car fit in with the image of safe, secure Volvo?
"Absolutely perfectly, in fact. We have for some time now been moving Volvo towards a more daring design language. The Hot Rod Jakob does of course go its own way, but I regard it more as a work of art than as a Hot Rod. The car is built with the very same Scandinavian design tradition as our modern Volvo models. Lean elegance, yet in a way that sticks out," says Volvo Cars design director Steve Mattin.
"That was exactly what made it so exciting. The paradoxes in the project. Challenging the usual perceptions of Volvo. And showing that it is perfectly possible to balance modern design and technology with classic Volvo and Hot Rod traditions," answers Leif Tufvesson when asked the same question.
