Land Rover announce new TD6 engines

**CSBrisie** · 20th April 2016, 08:41 PM

Everyone see this - end of the TDV6 and back to straight sixes!!

From car sales:

Jaguar Land Rover (JLR) will roll out all-new straight-six diesel and petrol engines next year and phase out all of its current ageing V6s.

Designed for all-wheel drive and rear-wheel drive applications, the new straight-six engines are part of the ?Ingenium? family of engines that already power -- in four-cylinder configuration -- the Discovery Sport and Jaguar XE.

Developed in-house at JLR, all engines will be direct-injection turbocharged 3.0-litres, says British mag Car, which broke the story, and will be offered in three states of power for both the petrol and diesel.

The petrol line-up will consist of 225/300/370kW outputs with the most powerful version of the 3.0-litre expected to come with twin turbos.

The diesel 3.0-litre, meanwhile, will be offered with 200kW in entry-level form, 250kW for the mid-spec diesel and a mighty 300kW for the range-topping straight-six that could replace the current 4.4-litre V8 in the Range Rover.

The advantage of the new Ingenium straight-six engines are their comparative light weight and low internal friction that's said to bring significant gains in fuel consumption.

The new engine is also said to tap into Jaguar's famous straight-six heritage.

Well - I guess D5 will get the low output diesels and RRS and Vogue will get the 300kw (what, 900nm torque?) engine.

Have always liked the straight 6 configuration for diesel engines large and small

It will be interesting to see if they have used the the M57 as a starting point; dual turbo's for sure. The little 4 cylinder Jag oiler is a pearler, but that doesn't say the 6 cylinder version will be the same. If they can match the longevity and low stress of the M57 they will have a BIG WINNER !!!

My main concern would be the choice of gearbox, given the long history of exceeding or nearly exceeding their selected gearboxs torque maximums by Land Rover. The 4.4 TdV8 8-speed box is on the maximum in standard form; and probably the cause for the lack of re-maps etc I would also like to see a tow function""with these new autos like Ford and GM have had since 03 in their bigger SUV's, it makes a big difference when engaged.

The 8HP95 allows 1000 Nm input so plenty of scope in the 8HP range.

The first ever RR model without a v8 at least being offered. It's probably not that surprising. The L405 td6 has been quite popular. LR will reduce the number of engine types for their large 4wd from 3 or 4 (tdv8, tdv6, 5.0v8 & SCv8 ) to basically 2.

Graeme that box would be the logical pick for this engine series from low output to the high output version. The spec of the box for these engines will be interesting. Given that L/R haven't upgraded their boxes in production models ! As far as I believe they still use the ZF8HP70 Series auto, whose maximum input torque is 700Nm the same as the output torque of the 4.4TdV8

And when they introduced the 6HP28 for the Supercharged version they still kept the 6HP26 for the other models. LR seem to stick with one box for the production run, regardless of upgrades.

The 6HP28 was fitted to the 3.0 D4 & 3.0 RRS but LR still used the 6HP26 for the other engines of the same year models.

The 8HP90 & 95 re bound to cost LR more money so providing the 8HP70 is doing the job then why not stick with it.
