Default Developments in engine 'downsizing'

I was struck by an odd sense of deja-vu recently when reading about developments in engine design at Peugeot and Ford. Peugeot describe this as 'a gamechanger' and Ford as "the freshest powertrain lineup in the industry". These engines will be produced in large volumes, powering the Peugeot 208 and Ford Ka, Fiesta, Focus, C-Max etc.

Both claim that they are introducing many new technologies. So what makes these new engines so innovative?

The Ford 1.0 litre Ecoboost features:
- three cylinders 999cc
- direct injection
- offset crankshaft to reduce friction
- exhaust manifold integrated in the cylinder head
- no balancer shaft
- variable valve timing
- low friction coatings to reduce loses
- less than 120g/km CO2

The Peugeot engine family will include:
- three cylinders 1.0 and 1.2l
- exhaust manifold integrated in the cylinder head
- variable valve timing system
- 'innovative' micro-hybrid Stop & Start System
- 99g/km and 104g/km CO2

So how can smaller, less powerful (but more efficient) engines provide adequate performance in mass market cars, even when turbocharged?

Ford say that the next stage is downsizing of the cars themselves to reduce weight, and less drag. There is a tantalizing mention of adding mild hybrid systems recovering energy when the car decelerates too.

Peugeot's new 208 is claimed to be shorter and lower than the 207 it replaces, weighing "a commendable" 110kg less. Cd of 0.29, CdA of 0.61 are also claimed.

Have we just seen the corner being turned here? Given the massive investment needed in new engine production, there must be real commitment to a future that looks just a little like the one Honda's engineers saw at the turn of the last century...
