10th Generation, all change!
Toyota seem very keen to change the Corolla image with the 10th
generation sedan. And as you can see from the images on this site
the design for the new Corolla is a dramatic departure from the
succession of dull, anonymously styled models that we've come to
expect. Is it beautiful? No. But it is interesting, and we will
settle for that. Finally a Corolla with a personality of its own.
Previously Corollas always looked like Toyota had taken all the
most boring design elements from other manufacturers and dulled
them down even further to insure that there was nothing
particularly outstanding or different.
Bigger and better
At 4,540mm long, 1,760mm wide, and 1,470mm high, the 2008 Altis
will be 10mm longer, 60mm wider and 20mm lower than the current
model. The wheelbase will be unchanged at 2,600mm, but with the
wider track and lower center of gravity the handling should be
noticeably improved. The extra width should also improve cabin
space, and although slightly lower, the Altis is still 50mm taller
than the Civic.
Previously Toyota had been restricting the width of the Corolla to
1,700mm to avoid a higher tax in Japan, which had resulted in a
awkwardly tall and ungainly looking stance for the current
model.
Dual VVT-i Engine(s)
Toyota engines have been leading the way in terms of refinement and
efficiency of late, and this is set to continue with the use of new
dual VVT-i engines in the 2008 Altis. While I'm not certain at this
time, it would seem logical for Toyota to make use of the new dual
VVT-i technology in the Altis, with the 1.6 liter 1ZR-FE and 1.8
liter 2ZR-FE being the two likely options for the Thai
market.
The 1.6 liter should produce a healthy 124 hp, while we can expect
the 1.8 to be around 140hp, on par with the 1.8 liter Civic power
output. But the 1.6 will represent the bulk of the sales
here.
The dual VVT-i engines take Toyota's cam shaft variation one step
further, allowing independent cam shaft variation for both intake
and exhaust timing using one electro-hydraulic variation system for
each of the cam shafts.
In the case of the 1.6-liter the torque curve dual VVT-i system
enables a very flat torque curve, which stays above 140 Nm from
2,000 rpm right up to 6,000 rpm, with peak torque of 157 Nm at
5,200 rpm.
This characteristic of the engine will mean smooth and powerful
acceleration from low engine speeds and excellent top-end power.
The new European Corolla uses the 1.6 dual VVT-i engine to achieve
fuel economy figures of 15km/l in the European combined fuel
cycle.
Although the 1.8 liter will offer even more power, the 1.6 is
plenty capable, with 0-100km in just under 10.5 seconds, and a top
speed of 195 km/h.
F1 inspired gear changes
The European Corolla has some interesting features that might be
discarded for the Thai model. Among them is a Formula 1 style gear
change indication light which shows the driver the optimum moment
to change gears. This feature is only on the manual version
(obviously), and since manual transmission are reserved for the
budget trim levels in Thailand, it's safe to assume that we won't
see this sort of feature. According to Toyota, following the advise
of this system will result in around a 5% increase in fuel
economy.
High end models which are fitted out with cruise control will have
a "speed limiter" feature. The driver can set the maximum permitted
speed, for example 120 km/m for expressway driving, and will be
able to accelerate normally until the car reaches this speed. The
system can be over ridden in case of emergency by simply kicking
down on the gas.
Also on the high end models we can expect to see the MultiMode
transmission with automatic selection, or manual sequential
selection available through steering wheel mounted shift paddles.
This is akin to the system in the top-of-the-range Civic, and will
probably be a 5-speed box.
All-new suspension
The current Corolla Altis is excellent at smoothing out bumps in
Bangkok roads, but this ride quality comes at the expense of driver
involvement. The new 2008 Altis should change all that, thanks to
brand new suspension, and a new electric steering system.
A newly-developed L-arm MacPherson strut is a compact and rigid
solution, which brings the suspension strut in-board of the wheel
hub to improve noise and vibration suppression. This design should
also improve straight line stability, and steering
responsiveness.
Rear suspension is by way of a new torsion beam which is a popular
arrangement as it allows increased boot space. The suspension
layout separates the coil spring and damper while allowing a wider
track for the cargo area.
The new Electric Power Steering (EPS) should provide a high level
of control, and make for easy work around town. Additionally, the
EPS system contributes to fuel economy since it only uses power
when steering force assistance is needed, and since it doesn't
require hydraulic fluid, it is also more environmentally friendly
than conventional power steering systems.
Safety
The Corolla has achieved a 5-star rating on the Euro NCAP safety
test. However, it is unlikely that the Thai model will come with
all nine (9) airbags available in the European market, but it is
possible that they will be optional at the high end.
A standard feature that should carry over (as standard) is the
Anti-lock Braking System (ABS) with Electronic Brake force
Distribution (EBD) and Brake Assist. There is really no good reason
to skimp when it comes to safety equipment, and ABS makes a big
difference.
The Altis will also likely have Vehicle Stability Control (VSC)
with Traction Control (TRC) on the options list.
Interior
The interior should resemble these images quite closely, however
some details could be borrowed from the Japanese model, which is a
little more conservative than the European Corolla.
Personally I hope that we get the European interior, but both are
acceptable. The main difference is the steering wheel, and the
dials with central metering displays for the European market, with
a more traditional looking arrangement on the Japanese model.
Regardless, the quality of the interior and the styling looks like
a step in the right direction, but still a bit conservative when
compared to the Honda Civic.
