Are we about to get the new engines early?

This article suggests we could get them earlier than we thought.

Vauxhall boosts Adam with all-new 1.0-litre turbo

Vauxhall_AdamVauxhall will launch a new 1.0-litre turbo engine option for the Adam at the 2014 Geneva Motor Show.

The new three-cylinder engine will be offered in two guises, 90hp and 115hp, with the promise of 62mpg economy and CO2 emissions as low as 99g/km.

More importantly, the new all-aluminium direct injection engine is a brand new development that should vastly improve the Adam’s currently mediocre engine portfolio.

It’s also mated to a new six-speed gearbox, which Vauxhall says has a snappy short-shift lever and much lighter engagement effort. Fans of other Vauxhall models, also take note: this lightweight gearbox is coming to other models, too.

The key draw of the punchy new 1.0-litre engine appears to be its big engine pulling power. Vauxhall says it has greater low-end torque and pulling power than non-turbo 1.6-litre engines; 122lb ft comes in at just 1,800rpm – 30% more than a comparable 1.6.

The 115hp model has a torque plateau that’s flat right up to 4,700rpm.

It’s set to be a refined new motor. Vauxhall says it has specifically focused on minimising the off-beat throb of a three-cylinder (some enthusiasts may say ‘pity’…), and has fitted a chain-driven balancer shaft to smooth things out. Even the turbo is a ‘low-hiss’ design. This helps it, during bench testing, put out less noise than comparable 1.6-litre motors.

“We not only set out to minimise fuel consumption and CO2 emissions, we also wanted to demonstrate that three cylinders can be just as refined as four or more,” says Dr. Matthias Alt, Vauxhall/Opel’s chief engineer, small gasoline engines.

“We tackled at source the balance, noise and vibration issues typical of conventional three-cylinder engines, and we’re confident Adam customers will be enthusiastic about the results.”

The new 1.0-litre turbo engine option will be sold in the Adam from this spring. It is also, MR hears, coming to the MG3 in time too – thanks to a joint development project with parent firm SAIC. That’s another car that’ll be greatly improved simply by fitting a better engine…

Could indicate application in the MG3; but the car is quite hefty in reality and I wonder if a 1.0l engine is going to be suitable.

The current 1.5 produces a maximum of 101 lbft so 122 lbft will be better and presumably it produces that all the way from 1,800 to 4,700 which will be significantly better than the 1.5 so yes, the engine is going to be more than adequate for nearly everyone, apart from those that want the MG CS's 230 bhp 2.0T!

The problems of a 1L turbo are vibrations and turbo lag. Unlike Ford, they have sorted the vibrations by fitting a proper balance shaft so it ought to be quite refined, effectively a small V6 where half the cylinders don't produce power but the others are turbo charged to make up. We will have to wait and see if turbo lag is an issue, the last 1L turbo I drove needed your foot to the floor to pull out of a side road just to get moving and then the turbo rapidly got going resulting in screeching tyres before you had a chance to reduce the throttle! That can be sorted via the fly by wire throttle but MG need to put a bit of effort into the tuning to make it a nice sporty drive.

The Adam was always going to get it's new engine first, GM built their factory first, GM will effectively do 6 months public testing of the engine before the SAIC factory comes online so that MG gets well sorted ones!

Is this the new 2.0 engine? NLE?

I've not seen anyone call it that,  but it is SAIC's own 2.0L Turbo Gasoline Direct Injection engine so I assume that it must be the NLE and responsible for reports of "very powerful" sounding MG CS prototypes - it has a decent size air intake.




And a nice picture of the E50 engine:
