USA August 2016

As if the P90D wasn't fast enough...

Record Edition

August accentuated the recent upward sales trend, with 14.482 units registered, a new record, with YoY sales up a very healthy 63%. With September known to be one of the hottest selling months of the year, expect sales to reach some 16.000 units, with YTD registrations headed to some 160.000 units.

The Star Of The Month was the Tesla Model S, winning for the Fourth time the Monthly Best Seller titls, delivering some 2.925 units, up 156% YoY, an impressive performance for a car that has been on the market for four years. 

Looking below, we assist to a stable ranking, with a best ever performance of the BMW X5 PHEV (Responsible for 21% of all X5 sales), with 876 units, while the VW e-Golf did a year best performance, with 454 units.

In the manufacturers ranking, Tesla (28%, up 1%) is comfortable in the leadership, while Chevrolet (18%) is doing a good job at keeping Ford (17%) at bay.

On a side note, 371 Toyota Mirai's and 2 Hyundai Tucson FCEV were registered, surprising numbers for the Toyota, that obliterated past performances and pushed the FCEV market share to a record 0.02% in August and 0.01% YTD..

Tesla Model S vs The Others

Pl	Model	Aug. 2016
1	Mercedes E-Class	4.623
2	Tesla Model S	2.925
3	BMW 5-Series	2.603
4	Audi A6	1.960
5	Cadillac CTS	1.426

  

The Model S has made it to the silver medal in August, surpassing the BMW 5-Series, with only the new Mercedes E-Class separating the Californian from the leadership, something that eventually might happen in September.

The Tesla Model S has probably peaked its sales by now, running tyre-to-tyre with the best sellers of its class and leaving its newest relatives (Model X and upcoming Model 3) an impressive model to follow. 

Tesla Model X vs The Others

Pl	Model	Aug. 2016
1	BMW X5	4.121
2	Mercedes GLE	3.756
3	Mercedes GLS	2.912
4	Volvo XC90	2.859
7	Tesla Model X	1.650

The Model X has a tougher job than the Model S, not only it has a larger (And more dynamic) number of competitors, but because of the SUV-Craze, they are selling faster than their sedan relatives, in August the Model X arrived in #7, waiting for a more streamlined production in order to reach a podium position.

V8 Release 5.4

Every six weeks, we create a new branch of V8 as part of our release process. Each version is branched from V8’s git master immediately before a Chrome Beta milestone. Today we’re pleased to announce our newest branch, V8 version 5.4, which will be in beta until it is released in coordination with Chrome 54 Stable in several weeks. V8 5.4 is filled will all sorts of developer-facing goodies, so we’d like to give you a preview of some of the highlights in anticipation of the release.

Performance Improvements

V8 5.4 delivers a number of key improvements in memory footprint and startup speed. These primarily help accelerate initial script execution and reduce page load in Chrome.

Memory

When measuring V8’s memory consumption, two metrics are very important to monitor and understand: Peak memory consumption and average memory consumption. Typically, reducing peak consumption is just as important as reducing average consumption since an executing script that exhausts available memory even for a brief moment can cause an Out of Memory crash, even if its average memory consumption is not very high. For optimization purposes, it’s useful to divide V8's memory into two categories: On-heap memory containing actual JavaScript objects and off-heap memory containing the rest, such as internal data structures allocated by the compiler, parser and garbage collector.

In 5.4 we tuned V8’s garbage collector for low-memory devices with 512 MB RAM or less. Depending on the website displayed this reduces peak memory consumption of on-heap memory up to 40%.

Memory management inside V8’s JavaScript parser was simplified to avoid unnecessary allocations, reducing off-heap peak memory usage by up to 20%. This memory savings is especially helpful in reducing memory usage of large script files, including asm.js applications.

Startup & speed

Our work to streamline V8's parser not only helped reduce memory consumption, it also improved the parser's runtime performance. This streamlining, combined with other optimizations of JavaScript builtins and how accesses of properties on JavaScript objects use global inline caches, resulted in notable startup performance gains.

Our internal startup test suite that measures real-world JavaScript performance improved by a median of 5%. The Speedometer benchmark also benefits from these optimizations, improving by ~ 10 to 13% compared to 5.2.

V8 API

Please check out our summary of API changes. This document is regularly updated a few weeks after each major release.


Developers with an active V8 checkout can use 'git checkout -b 5.4 -t branch-heads/5.4' to experiment with the new features in V8 5.4. Alternatively you can subscribe to Chrome's Beta channel and try the new features out yourself soon.
