Volvo to Introduce New V70 with New Engines and E85 Option

| The new V70 wagon. |
Volvo will introduce the third generation of its V70 wagon at the upcoming Geneva auto show. The redesigned model will offer a new version of the five-cylinder D5 diesel, a four-cylinder flex-fuel option, and a new top-end six-cylinder twin-scroll turbo engine.
The second-generation D5 five-cylinder diesel option delivers 136 kW (185 hp) of power and 400 Nm of torque across a wide rev range. The new D5 features a new electronically controlled turbocharger, more advanced multi-point injection technology and new engine management system. A diesel particulate filter is standard. Estimated fuel consumption is 6.5 l/100km (36 mpg US), with CO2 emissions of 173 g/km.
The Volvo V70 will be available in an FlexiFuel E85 alternative during its first production year. The FlexiFuel model uses a four-cylinder naturally aspirated engine producing 108 kW (145 hp). Further figures on the E85 model will come closer to release.
The new six-cylinder gasoline engine is based on the compact 3.2-liter in-line aluminum engine introduced in the new S80 in spring 2006. While the naturally-aspirated 3.2-liter version is available in the V70, a new, slightly downsized 3.0-liter turbo version is available as the top performing unit.
The smaller displacement in the 3.0-liter engine—due to the slightly narrower cylinder bore and shorter stroke—is offset by the twin-scroll turbocharger, which divides the inflow into two lots of three cylinder each.
Twin-scroll technology permits use of a more compact and uncomplicated turbocharger and provides response on a par with that of conventional twin turbochargers. The 3.0-liter turbo produces 210 kW (285 hp) of power and 400 Nm (295 lb-ft) of torque. Volvo’s preliminary rating of fuel consumption (combined) is 11.2 l/100km (21 mpg US), with CO2 emissions of 267 g/km.
The 3.2-liter normally aspirated engine produces 175 kW (238 hp) of power and 320 Nm (236 lb-ft) of torque. Preliminary fuel consumption is 10.3 l/100km (22.8 mpg US), with CO2 emissions of 246 g/km.
The engine also has a valve system with dual cam profiles on the inlet side. With CPS (Cam Profile Switching) the inlet valves can be lifted to two different heights in response to variations in engine revs and load. The engine also features a variable intake system (VIS) consisting of two throttle valves that adjust the volume of the inlet manifold to suit the current driving conditions.

Shouldn't the flex-fuel engine have a turbo to increase the effective compression ratio and hence take advantage of E85's higher octane rating?

Unfortunately, if you raise the compression to fully utilize the octane rating of E85, you will no longer be able to use normal lower octane gasoline in the engine.
E85 is not sufficiently available to tune an engine for that fuel only. Besides, when you get past the feel good part of using E85, it is a very expensive fuel to use compared to gasoline (E85 is generally sold at a premium price and it gets poorer gas mileage.)

I can't understand why Volvo won't abandon the T6 concept. For a while it seemed like it would disappear, but now it reappears again in the V70. Why? Power output is only slightly higher than the naturally aspirated R6 (238 hp) or the turbocharged T5 (260 hp), and slightly lower(!) than the R engine (300 hp), but fuel consumption is enormous. Who would want that? It get's even more embarrassing when comparing with BMWs 3.0 L engines.

Bill said: if you raise the compression to fully utilize the octane rating of E85, you will no longer be able to use normal lower octane gasoline in the engine.
Understood. That's why I suggested using a turbo. Turbo engines are normally lower compression ratio than their non-turbo counterparts. You can bypass the turbo if you are using gasoline in an E85 optimized engine (see Saab BioPower).
PS it took approx 75 seconds to see this in preview - a real discouragement to posting!

I gave up consideration of buying another Volvo when Ford took 'em over, knowing their cars would be "fordalized" in time. Looks like it's happening. Many of the the true old Volvo engines, and their Lexus transmissions, easily go 200 to 250 thousand miles. That's why we affectionately called 'em "bricks." The Volvo straight six double cage engine was a sweet design, albeit expensive to manufacture. I suspect Ford has already decided how to make it cheaper, not inexpensive if you know what I mean

"fordalized" I like that. You are correct. I put a question to this community. Do you think Volvo will survive Ford's demise?
Did you check out Ford's superbowl commercial???? That's right!!! They didn't have one! Greed is killing Ford I don't see that changing before it's too late.
We could really use a good reliable volvo diesel here now, but due to Fords nearsightedness/profit preoccupation Volvo's ULEV diesel project was killed. So now what? We wait 5 years? Ford doesn't HAVE five years. Criminey sakes! They knew low sulfer diesel was coming, why didn't Ford get ready for that???? Did they bank upon getting the low sulfer requirements put off? Or maybe even canceled? Just like California's ZEV standard? Somebody help me to understand them cutting thier own throats here because I just don't understand why they committed suicide the way they did.

Please, I'm a business manager in Amsterdam, I'm currently working on energy projects. I have about 20,000 hectares of land in Ghana, which I would like to use for growing cassava for Ethanol projects.
For this project, I'm looking for interested partners to set up the Ethanol plant in Ghana.
The government of Ghana is working on Renewable energy legislation, so permits and environmental regulations won't be a problem.
Best,
Osafo.
