Ford's project car that will be shown at the upcoming SEMA Show is a custom 1934 Ford Coupe. Instead of a traditional flathead V-8, it will have the new twin-turbocharged 3.5-liter EcoBoost V-6.
Ford is building this car along with Detroit Street Rods. Robert Smith, president of Detroit Street Rods, said that the decision to use the EcoBoost engine as the powertrain was easy to make.
He called the result as the perfect hot rod marriage of advanced technology for power and legendary automobile design. For now, the specific figures for the 3.5-liter in this particular application are not available. However, we do know that the engine is largely stock. The biggest change lies with the turbochargers.
They're actually stock parts, but engineers had to modify the engine's intake, exhaust, and intercooler in order to position them within the confines of the narrow engine bay.
The EcoBoost motor is attached to a Tremec five-speed manual transmission, which sends power to the rear wheels. It's rare that the motor is seen to be used in a longitudinal configuration. The only other time we´ve seen this is in the 2011 F-150.
The EcoBoost technology provides a solution that proves that displacement can have a feasible replacement for displacement, shared Dan Kapp. Kapp is a director at Ford Powertrain Research and Advanced Engineering and is expected to be a member of the briefing panel that will discuss the SEMA "Driving Green" technology during the auto show.
With the increasing demand from consumers for fuel efficient cars, the company remains committed to making new ones that have the best fuel economy, Kapp added. It is important though that performance should always be ensured, he continued. Meanwhile SEMA vice president of Vehicle Technology John Waraniak shared that SEMA is currently in a position to show that a car can have power and be environment-friendly but not at the expense of performance or the wow factor.
Waraniak added that hot rods offer a good blank canvas especially for SEMA-member companies and a good example of this is the '34 EcoBoost hot which has green technology utilized in a way that even performance buffs would appreciate it.
Compared to the larger displacement engines, engines that use EcoBoost have fuel economy that is better by 20% while CO2 emissions have dropped by as much as 15%. This is due to its use of direct injection technology and turbocharging technology.
Kapp said that the advantage of the EcoBoost is that it allows downsizing to get better fuel efficiency but at the same time it increases the power. The company can lower the size of the engine like putting a V-6 against a V-8, he added, but power is higher since the use of a turbocharger can provide power and torque similar to a larger engine.
