The new mtu 16V 2000: A Power Class of its Own

• Unparalleled Power-to-Weight Ratio for Yachts from 60 to 120 feet
• Over 380 Engines of the new Series 2000 Common Rail already sold
• mtu: Market and Technology Leader around 2000 HP
• Considerable Enhancement of the mtu Product Range

mtu, the established leader in power for 80 foot plus yachts, further broadens its power offerings for the yachting industry. After the introduction of the 8 and 10 cylinder 2000 Common Rail engines in 2004, mtu launched its new 12 and 16-cylinder versions of that series at the Miami International Boat Show 2005. The engines have been received extremely well by the market. Over 380 units have been sold so far.

With a power of 2400 HP and a weight of under 3.4 tons, the 16V 2000 Common Rail, boasts a power-to-weight ratio of 0.71 HP per kilogram. This is unparalleled in the industry. Peter Grosch, Senior Vice President Sales of DaimlerChrysler Off-Highway said: “With this engine, we open up an entirely new power class. The 16V 2000 Common Rail comes in at a very attractive power of 2,400 HP, allowing yacht builders to enter new speed segments.” Because of its lightweight design, the 16V 2000 Common Rail aims at fast boats in the 80-120 foot range, allowing conventional 80 foot boats with twin engine installations to reach speeds of more than 50 knots. Conventional 100 foot boats with two of these engines are reckoned to still reach 40 + knots.

In the class of yacht engines over 2000 HP, there is a huge gap between the new mtu Common Rail engines and the best competitor’s engine which comes at a weight of over 6.5 tons for 2250 HP, equaling a power-to-weight ratio of 0.34 HP per kg. This is twice as much weight per HP as with the new mtu engine.

Equally new is the mtu 12V 2000 Common Rail, an engine with 1800 HP. Weighing only 2.8 tons, this engine, too, is the clear industry leader in terms of power-to-weight ratio. The 12V aims primarily at the 60 to 100 foot class of yachts, both in the cruising and sportsfishing market.

mtu: Market and Technology Leader around 2000 HP

When comparing different yacht engines with more than 2000 HP (see overview at the end of this press release) it becomes evident that mtu engines are ahead of the competition in a number of ways: The best positions in terms of power-to-weight and power-to-size ratio are occupied by the new 12V- and 16V 2000 Common Rail engines. In terms of size, they are equally in the lead. The 16V 2000 Common Rail needs not even half the space of the best competitor’s engine and has yet 150 HP more power, the 12V 2000 Common Rail still takes 10 per cent less space than the best competitor of the same power. The space and weight saved can now be used for additional room on board to receive more guests and accommodate more equipment. The weight savings can also be turned into more fuel capacity - and consequently into longer cruising ranges.

Fuel consumption of the 2000 Common Rail is equally good, compared to competing engines. With values of 210 and 211 g/kWh respectively, they allow for very long cruising distances. Indeed, comparing the new 2000 Common Rail to modern competitors’ engines under identical conditions, it became clear that a test boat using the new 10V 2000 Common Rail engines had an over 10 per cent longer range than before. The same is true for the 12V and the 16V engines. The 12V for example takes seven per cent less fuel than a competitive engine of the same power (1800 HP).

Considerable Enhancement of the mtu Product Range

Comparing the new 16V 2000 Common Rail to the previous 16V 2000 engines - which had set the standards in yachting for the past eight years -, the improvement becomes evident immediately: The new engines are 20 per cent more powerful than the previous ones and at the same time they are 15 per cent lighter and 20 per cent smaller. The fuel consumption has improved, too, and has gone down six per cent to 210 g/kWh.

The higher power output at lower fuel consumption as well as the small dimensions are mainly due to the improvements mtu was able to reach by using the advantages of its key technologies. The 2000 Common Rail engines employ a common rail system of the third generation, redesigned electronics and a new, efficient turbocharger system.

Peter Grosch said: “Technology is what sets us apart from the competition. But we don’t pursue this as a goal in itself. We push technology forward because we want our customers to benefit from it.”

The new 12V and 16V 2000 Common Rail engines are scheduled to start series production as of July 2005 and are expected to be available for customers as of September 2005.
