ELR driving confidence is enhanced by advanced suspension and damping systems, including Continuous Damping Control – which adjusts damping every two milliseconds – to maintain optimal vehicle ride control over varying road surfaces and profiles. The ELR rolls on 20-inch wheels with specially engineered low-rolling-resistance tires designed to balance excellent control and cornering capability with efficiency.
A solid, stable foundation underpins the ELR, featuring a body-frame-integral structure with main underbody rails running continuously from front to rear. Advanced, high-strength steels add strength and conserve weight. Additional contributors to the ELR’s driving experience include:
◾Wide front and rear tracks – 62.1 inches (1,578 mm) in front and 62.4 inches (1,585 mm) in the rear – along with a long wheelbase (106.1 inches / 2,695 mm) and a low center of gravity
◾HiPer Strut front suspension featuring lightweight forged aluminum components for reduced weight and more nimble, responsive action
◾Dual-pinion, rack-mounted electric power steering system with premium ZF steering gear designed to provide excellent feedback while helping to save fuel
◾A semi-independent rear compound-crank suspension with Watts link that incorporates weight-optimized trailing arms to absorb lateral forces, allowing the suspension to be tuned to handle vertical, forward and rearward motions
◾Hydraulic ride bushings in the front and rear suspensions
◾An electro-hydraulic regenerative brake system that captures energy and sends it to the battery pack
◾Standard chassis control systems include anti-lock brakes, traction control and StabiliTrak electronic stability control.

Superior suspension components (vis a vis the Volt) are doubtless required to counteract those beautiful, but brick-like, 20 inch wheels. And the "long wheelbase" is barely longer than the Volt's (106.1 vs. 105.7). Some creative marketing at work in this press release, but I guess that is to be expected.
The front doesn't look much different: same components and same subframe. They put in higher-end shocks with electronic damping control and (possibly) a slightly upgraded power steering. On the back, its the same twist-beam, but with a Watt's link added. That comes over from the higher-end Opel Astra model.
The huge 20 inch rims are worse in every aspect except the looks department, so it remains to be seem whether the overall experience is much better.
Well perhaps to some people a strut is a strut, and a steering rack, just a rack.
But the reality is ALL of these major steering and suspension components are significantly upgraded to performance grade systems.
The 20 inch wheels support a wider tire with a performance rated aspect ratio- definitely an improvement in the handling department (not just looks) and Cadillac's electronic Real Time Damping (RTD) system is something not offered on anything other than a Cadi
No matter. When Consumer Reports does its review they won't notice how great the ride is, but will complain that if you drive in a blizzard with temps under 15F you don't get 35 miles of range.
It doesn't say hydraulic regen, it's electro-hydraulic, and there is a distinction
But essentially "brake by wire" EHCU braking systems as used in hybrids and EVs are all very similar (in this case the EHCU aspects are really near identical to the Volt)
The only thing really special about the ELR in this regard is the regen-on-demand system via the steering wheel paddles...
WOT
So lets see, as of now it will be available in black metallic, light black metallic, lighter black metallic and red. Lots of choice there. No blues, no greens, no whites.
A few years ago I somewhat seriously considered a used Ferrari 348. Because, after seeing all the me too red black and occasional yellow ones, I saw a metallic emerald green one that I thought was just awesome.
My question is how does GM expect to sell this car full of technological wonders at a supposed $70k+ when it is having issues meeting sales figures on the $45k Volt.
Many of these suspension components should have been offered in the Volt as an SS. Also the Acceleration needs to be increased for the Caddi for the $$.
