BMW AG:
3.0L DOHC I-6 Turbodiesel
Several Ward’s editors averaged about 30 mpg (7.8 L/100 km) driving the 335d, a car that sets the pace for a luxury clean diesel.
Audi AG:
2.0L TFSI Turbocharged DOHC I-4
Audi stands as one of of the few luxury brands confident enough to stake its reputation on a 4-cyl. engine in a fiercely competitive 6-cyl. market.
Toyota Motor Corp.:
1.8L DOHC I-4 Hybrid
It seems appropriate the first time the 10 Best Engines list has two hybrids on it, the Prius would be one of them. One Ward’s editor seeking maximum mileage averaged 56.5 mpg.
Fuji Heavy Industries Ltd.:
2.5L Turbocharged DOHC H-4 Boxer
Subaru’s excellent 2.5L turbocharged boxer engine provides the ideal mix of restrained power and frugal sensibility. It’s the cure for the boring family sedan.
Volkswagen AG:
2.0L Turbocharged DOHC I-4 Diesel
The case for the Jetta TDI is even more compelling this year than last, when diesel fuel was up to $1 more expensive per gallon than gasoline. That gap has closed considerably.
Hyundai Motor Co. Ltd.:
4.6L DOHC V-8
The intense engineering focus on noise, vibration and harshness, and reducing friction and mass, seems evident with every spin of the crankshaft.
Ford Motor Co.:
2.5L DOHC I-4 HEV
A winner in 2009 when we tested it in the Escape Hybrid, the system in the Fusion Hybrid boasts mechanical, engineering and software upgrades.
Audi AG:
3.0L TFSI Supercharged DOHC V-6
The new S4 sprints 0-60 mph in 4.9 seconds. The old V-8 did it in 5.3 seconds. With a towering specific output of 111 hp/L, the 3.0L TFSI strikes like an archer’s arrow.
Ford Motor Co.:
3.5L Twin-Turbocharged DOHC V-6
What ultimately convinced Ward’s jurors EcoBoost is the real deal is the stunning 350 lb.-ft. of torque the V-6 produces at just 1,500 rpm.
General Motors Co.:
2.4L DOHC I-4
There are lots of mainstream 4-cyl. engines in cars and CUVs, but none of them makes as much power as GM’s 2.4L direct-injection Ecotec in the Chevy Equinox.
