Default Renault-Nissan Alliance unveils brand-new V6 dCi Diesel engine

Quote:
This is the first V6 engine designed and created by the Renault-Nissan Alliance. It will be utilized by top ranged vehicles to address the increasing international demand for powerful engines but are also both economical and environmentally safe. The cooperation of the Renault-Nissan Alliance has made it feasible for Renault and Nissan to provide a high-tech, first-rate powertrain to their clients around the globe.

The latest V6 dCi (V9X) is a demonstration of what the Renault-Nissan Alliance is really about. The engine was designed by the two companies, has been put together in a Renault plant and will be installed in Renault, Nissan and Infiniti vehicles. This approach makes it possible to divide the costs, to profit from economies of scale, and to present more vehicle versions to buyers.

The specifications of the new engine were designed to address the demands of buyers of Renault, Nissan and Infiniti, which demonstrates that the engine can be utilized by different types of coupes, saloon, and SUVs and can also be advertized and sold in different parts of the planet, such as Europe and the US. This is the reason why it has been determined to utilize a ‘V’ configuration. Engines like this can be installed either longitudinally (as in Nissan/Infiniti vehicles) or transversally (like in a Laguna).



The latest V6 dCi motor originates from other Renault engines like the 2.0 dCi, and therefore, taking advantage of the accumulated knowledge during the development of this 4-cylinder engine. Since the upper portion of the V6 dCi are very much like to that of the 2.0 dCi, the design of the later engine was quicker, and more economical. Using the latest technologies also ensure superior quality, which is a main concern for Renault, as the firm’s dedication is to put the Renault Laguna as one of the top three vehicles in its segment with regards to product and service quality.



It is the first system in the planet to merge three different functions to improve fuel efficiency. These functions consists of an ECON Mode which controls engine, transmission and other powertrain parts to back more fuel-efficient driving; a guidance function that assists drivers in becoming more fuel efficient behind the wheel using the color of the speedometer display; and a scoring function that provides immediate and long term feedback on driving techniques, after each ride.

I wonder if Renault will dare running that engine in the new Laguna Coupé.

I found the projected power output of this engine in an older article (from September 2007): http://www.greencarcongress.com/2007...t-30l-v6-.html

Here is a quote from that older article:
Quote:
[...]The engine develops 195 kW (261 hp) of power and maximum torque of 550 Nm (406 lb ft) at 1,750 rpm with targeted CO2 emissions of less than 200g/km.[...]

I think Nissan is planning to use it in the Maxima first.
But, they could use it in a lot of cars in their line-up. It would be a good alternative to the 5.6L V8 in the Titan and Armada. It should return much better fuel mileage than the V8 while churning out more torque right off idle.

While I am no huge fan of diesels in the USDM (because of the price of the fuel), I would still be very curious what kind of mileage this engine could roughly offer (which obviously depends greatly on the size/type of vehicle).

I just want it in the Altima because it's sexy.

According to this article at http://indianautosblog.com/2008/11/r...-diesel-engine, this engine comes in 2 power levels depending if it's mounted transversely (235HP/330ft.lb) or longitudinally (265HP/400ft.lb).

It looks like the 235HP version which is currently in the new Renault Laguna Coupe (about as large as a Nissan Altima Coupe) is supposed to return 22MPG in the city, 41MPG on the highway and 33MPG combined.

Well, this engine redlines at 5K instead of the usual 4.5K. Anyone that has driven one of these modern diesel engines knows that it's sporty enough for most of us.

A valid argument (among others) against using a Diesel engine in a sport coupe would be weight. But, we do not need to worry about this. Nissan will probably not put this Diesel engine in the Z (it may find its way to the Nissan Altima coupe though).
