Because a new engine designed to run on new systems would work
better than an old engine constantly upgraded to cope on new systems.
A new 1.4 - liter four - cylinder, paired to a five - speed manual or a CVT automatic, has 14 more
horsepower than the old engine, now at a semi-respectable 98 hp.
Engine outputs are increased, but not dramatically (up 10bhp to 271bhp in the downsized 2.7 - litre Cayman and 5bhp to 321bhp in the 3.4 - litre Cayman S) although both motors have more generous power curves, so they produce more
power than the old engines across the rev range.
The new aluminum - block 1.5 - liter four, which replaces the current Volt's iron - block 1.4 - liter four, has a compression ratio of 12.5:1 (versus 10.5:1 for the same engine used in conventional applications) and weighs about 100 pounds
less than the old engine.
The new 5 - litre V8 — purer
sounding than the old engine with less supercharger whine — delivers an astonishing hit from low revs, yet the rear tyres have little difficulty laying this on the road.
We will have a new engine family that is very highly modular and can be structured for four, six or eight cylinders, not only with performance in mind but it must perform better and be more
efficient than the old engines.
If this happened to your Camry, maybe the mechanic putting it in made an incorrect electrical connection, or the electrical circuit needs a higher rated
fuse than your old engine.
Plus, it generates peak power and torque lower in the rev
range than the old engine, so this larger 2.0 - liter is never working quite as hard to move the Elantra.
This system provides greater
output than the older engine, with 241 bhp (180 kW) and 600 N ⋅ m (440 lb ⋅ ft) whilst reducing CO2 emissions by 10 percent when first introduced and in 2014 increased to 188 kilowatts (252 hp).
The lower bumper features a skid plate and has LED lights at either side, while the long bonnet bulges upwards - hiding the brand's new variable - compression turbo engine, which aims to combine performance and efficiency much better
than older engine designs.
Although it produces noticeably more
power than the old engine, there is no real reduction in fuel economy, thanks equally to the new engine's improved design and the new transmission's seven speeds and sophisticated electronic controls.
Chrysler's 3.6 - liter Pentastar V - 6 replaces the Porkchop's old 3.8 - liter V - 6, and is both lighter and more
powerful than the old engine.
With 369 lb ft, the new forced - induction unit also offers 45 lb ft
more than the old engine, and it's developed 3900rpm earlier, at just 1700rpm.
More importantly, it produces 15bhp more
than the old engine, taking maximum power to 306bhp at 6400rpm (which, if you like those kind of details, is 6bhp up on the first - generation 996 Carrera).
More specifically, it provides 290 horsepower — 8 more
than the old engine — and 265 pound - feet of torque — 12 more than the old engine.
The 500SL, which is the same car as the 300, but with a bigger engine, has a 32 - valve 5.0 - liter V - 8 that develops 100 more horsepower
than the old engine.
