Future of engines for large SUVs

With the recent bad press for diesel vehicles one wonders what developments the likes of JLR are thinking about for future Range Rovers.

My wife has changed her car and we have taken a Ford Fiesta Titanium with the three cylinder 900cc eco boost 125PS engine. To say we were impressed with the performance of the engine would be an understatement. 0-60 9.4 secs, 122 MPH Actually the acceleration seems faster than that. Free road tax. Compensates for my £490 road tax.

The point is what could be done with this technology on a RRS with a petrol engine? Take a 2 litre engine supercharged with 250-300PS or more. Yes I know torque will be an issue but that is what a bright young techie needs to crack. Current Merc GLE 3.5d 2016 model, 2011 RRS HSE standard
Previous 2012 FL2 liked but boot too small
Previous to LR's 3 x Merc E320 estates - fantastic load carriers and long distance cruisers, ultra reliable. Only changed as needed a 4x4 high tow vehicle. Did have a 1955 early LR drop down windscreen and fuel tank under the drivers seat; again very reliable and super rugged.

3.0 Supercharged V6 petrol, circa 300bhp currently used in the Jag, and overseas LR models Thumbs Up

The petrol Ingenium engine is still a good year away yet, but offers high output, small capacity engines, similar to the Ecoboost Thumbs Up

Power is basically torque x revs so if you develop 250PS at c.5000rpm then you'll be developing reasonable torque anyway. You'd need to choose gearing appropriate to the rev range and a low range box would help with that.

Ford have a 250bhp/275lbft 2L turbo petrol, for example. Stick that in front of an 8 or 9 speed auto 'box with a 2-speed transfer case and you'd be good enough for most, especially if you can get the weight of the vehicle down in the process. Additionally, if you use a hybrid system you could use electric power to supplement the engine - if you're really clever you use the electric in tricky situations where the extremely controllable output from the electric motor would give traction benefits. Hybrid keeps the green brigade happy too. I could imagine a petrol FWD LR with electric RWD when traction is required. No need for diff locks etc. as the rear wheels could be independently driven so only the wheel with traction is driven. The front end can use existing traction control strategies with a locking diff if considered necessary.

The future is not inefficient big engines with masses of excess torque, it's efficient small engines supplemented with electric motors. Add clever control electronics and intelligent drive trains and you get good on-road performance with good off road ability too. Cutting drive to everything behind the transfer case would help with mpg - essentially what happens now with the "small" LR stuff. 2012 SDV6 - it's missing a couple of cylinders

According to Auto-Express (I never believe a word they print!) claims that Disco5 will be launched with the 2.0l Igneium engine. With scepticism about diesel emissions figures by the general public I think Land Rover will have to think PDQ about putting the V6 S/C petrol engine already fitted to export models into UK and European cars, Auto-Express says it is going into Disco5 too! Maybe there will be some new engines for 2016.MY in March? 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Personally impressed with these new Eco boost engines. 2017/2018 I bet we see them in the RRS AS PART OF A HYBRID OPTION. Current Merc GLE 3.5d 2016 model, 2011 RRS HSE standard

The thing is you get these small engines working harder and harder putting out these great outputs, but how long will they last before they need a rebuild etc. 2008 G4 RRSport TDV8 current

One would assume it may be dependant on how often you use the extremes of its performance Thumbs Up

The current range of large engines aren't exactly paragons of reliability. The last bomb-proof engine LR used was probably the 2.25 petrol (and that was intended to be a diesel too I believe). It wasn't exactly "high performance" though.

A small high performance engine can be long lived if the accountants don't stick their oars in to it. 2012 SDV6 - it's missing a couple of cylinders

I guess I'll stick with my totally inefficient gas, guzzling 500bhp 5.0L S/C for the time being.

Also one could make an argument for not changing now staying with my TDV6 and waiting to see what comes along. The depreciation on a 2011 RRS will be far less than buying new now and in three years time with new petrol engine on line seeing a huge depreciation in a diesel RRS.

OK lots of suppositions made but perhaps worth considering. Current Merc GLE 3.5d 2016 model, 2011 RRS HSE standard

I realise the RRS2 has shed some weight and has a result also a couple of seconds off the 0-60 but the DS I'm driving round in at moment is as quick as MY13 Black Edition I had previously despite losing 2 cylinders and a 1000cc but feels just as big - so I'd say that's good progress Cool

Admittedly I'm not seeing anywhere nr the 53 combined mpg but around 40 is a big improvement on around 30 Very Happy Wanted a Series 2 LR since childhood but previously owned MY16 Disco Sport HSE TD4 Auto, MY13 RR Sport Black Edition TDV6 Auto, MY10 RR Sport HSE TDV6 Auto, 2007 Freelander 1 Freestyle TD4 Soft Top, 2009 Freelander 2 GS TD4 Auto, 2007 Freelander 2 GS TD4, 2004 Disco 2 Metropolis Auto, 2002 Disco 2 GS, 2000 Freelander 1 SE TD4 SW

Still hoping for a S2 one day!
