On one of his frequent visits to Australia, automotive mogul, Roger Penske launches the new 15 litre MAN D38 prime mover. Fresh from watching the DJR Team Penske V8 Supercar racing team compete at Bathurst over the weekend, Penske attended the launch in Brisbane this week.
“I try to mix my business with my golf game, and my golf game at the weekends is racing,” said Penske. “We had a great time at Bathurst, when you lead laps in a race and you are competitive, two cars in the shootout was a big day for us. That’s got to transfer across into our business. Three years ago we decided to invest in Penske Commercial Vehicles. We had some good people and a good customer base, but, obviously, the opportunities were many times greater than what we started with.”
The first major launch of an all-new vehicle since the takeover sees the MAN brand, finally, enter the Australian market with a 15 litre heavy duty prime mover engine. The MAN TGX D38 engine produces 560 hp (411 kW) and around 2,700 Nm of torque (2,000 ft-lb).
The 15.2 litre, six-cylinder, Single OverHead Cam common-rail injected, twin turbocharged power plant, designated D3876, has a ‘Top Down’ system, pumping coolant from the engine top to the bottom, minimising cylinder head stress while protecting the injectors and exhaust valves.
Domed valves are another innovation. According to MAN, the design will prevent deformity, additional convex shaping strengthens the valve disk and increases the service life of the valve seating ring. This is said to be critical in later technology engines whose task it is to attain and maintain stringent emission standards over a prolonged period.
A Turbo Exhaust Valve Brake (TEVB) gas flap has been used for the first time, delivering a braking capacity of 600 kW, which is continuously available in engine braking mode. Cable routing is encased in a foam-filled harnesses to reduce material fatiguing vibration, another first for MAN.
MAN reckon the Euro 6 compliant engine consumes up to three per cent less fuel than an equivalent 540 hp Euro 5 engine, due to its third-generation, high-pressure common rail fuel system, which injects fuel into the cylinders at up to 2,500 bar, resulting in finer atomisation and lower particulate levels.
The PCV organisation now has a credible cabover B-double prime mover to match the other heavies in the market, for the first time. The MAN brand has consistently under performed here in Australia, but this introduction is seen as an opportunity to rectify this situation.
“I think the metrics we’ve seen and some of the experience we have had on the MAN test vehicles has been quite positive,” said Penske. “Some of the feedback I have gotten is we have to be a better company here in Australia, from a service perspective. We look around the country and we see the service network able to grow over the next 18 months. Even though the market is down, we are continuing to invest.”
